Filter Care
Normally, filter requires no maintenance and no calibration. It is recommended, though, to
periodically inspect filter for overheating and to clean its surface with dry cloth.
During its normal operation filter may have elevated temperature which would feel “warm” to
the touch, but not what is considered “hot.” If the filter does feels “hot” to the touch (more
than 700C or 1580F), turn off equipment that is powered via the filter immediately. First,
verify that the total current load does not exceed filter’s maximum rating. Keep in mind that
sometimes power rating of equipment is “typical” rather than “maximum” - it is prudent to
load filter to no more than 75% of its capacity to accommodate for such situations. Then, check
if the heat dissipation of the filter is obstructed by improper installations such as objects
placed on its top or lack of space around it for proper ventilation, or its placement in small
confined space. If such problem is identified, correct it, let the filter cool down and turn
equipment back on. Check within 30 minutes and then within an hour the temperature of the
filter. If the filter still feels “hot” to the touch, turn your equipment off, disconnect filter from
the circuit and discontinue using it. For warranty or other repair contact factory or its author-
ized distributors.
CleanSweep® power line filters do not contain any components that may deteriorate under
normal use. If you wish to verify the proper operation of the filter use power line EMI Adapters,
such as MSN01 or MSN12 (shown on page 6) and oscilloscope to measure high-frequency
noise before and after the filter.

Thank you for buying CleanSweep® filter!
Your new CleanSweep®power line filter will provide your sensitive equipment with AC power free
from electromagnetic interference (EMI) and power line transients. Such artifacts on power lines
and ground cause numerous equipment malfunctions, including lock-up, erratic response,
software errors, and other often “unexplained” behavior. Excessive noise can also cause
damage to sensitive components via induced electrical overstress (EOS). For more details on
this subject please visit Library section on our web site www.onfilter.com.
Safety First!
CleanSweep®filters operate with high voltage that may cause property damage, injury and
death. Always observe safety measures when using power line filters. Here are some of the key
safety precautions you should take:
WARNING
Do not exceed filter’s maximum rating - it may cause overheating
Do not place anything on top of filter during its operation to avoid overheating
Use filter after the fuse of no more than specified max. rating
Use only with the power cord supplied by manufacturer
This filter is not for household use
Filter must be plugged into a properly wired grounding type outlet
No serviceable parts inside - do not open. High voltage is present inside.
Brief Summary
CleanSweep® EMI filters reduce noise on power lines providing clean power to your equipment.
High levels of noise (also called conducted ElectroMagnetic Interference - EMI) interferes with
normal operation of electronic equipment and can cause physical component damage inside the
equipment. Noise on power lines is common in industrial and office environment and the only
practical way to deal with it is by using properly-designed filters. OnFILTER’ CleanSweep®EMI
filters are designed to effectively suppress noise and short surges on power lines and ground in
real-life environment.
Installation
Proper placement of the filter helps to assure its continuous operation for a long time. Please
follow these requirements for installation:
Place filter horizontally with its label facing up
Install filter in a dry location away from debris and from the possibility of spillage, including
from floor cleaning
Ambient temperature at the place of installation should not exceed the range of 50…400C
Install filter away from traffic where it does not interfere with movement of personnel and
machinery.
Install filter close to your equipment
Do not install filter in small confined spaces with restricted air circulation in order to avoid
overheating. Allow at least 15cm (6") on each side for proper ventilation

Achieving the Most Results from Your Filter
There are two basic ways to place EMI filters for the best results:
To isolate strongest noise sources
To protect EMI-sensitive equipment
Noise on power lines can be generated by equipment anywhere
in the facility, which makes it very difficult, if not practically im-
possible, to identify a specific source of noise. It is possible,
though, with proper instruments, such as OnFILTER’ EMI Adapter
MSN12 (pictured to the right) and an oscilloscope, to identify
the most likely noise polluters.
The most effect can be achieved by identifying the most sensitive
equipment in your facility and powering this equipment through
the CleanSweep® filters. It is also beneficial, once you know
which equipment generates the most noise, to place this equip-
ment behind its own filter as well since CleanSweep® filters sup-
press noise in both directions.
Try to place the filter as close to the equipment it will be protect-
ing as possible - this will reduce influence of radiated noise on
the cables after the filter.
Mulple Load and Filter
When using more than one equipment plugged into the filter’ output, keep in mind that:
Total current consumption shall never exceed maximum filter rating, and
There is no filtering between the loads at the output of the filter
The latter is illustrated in the figure to the right. As seen,
the noise from one equipment easily propagates between
equipment connected to the output of the filter. In short,
if you want to protect a particular piece of equipment
from noise, do not connect any other equipment to the
output of the same filter. For example, if you want to
protect your measurement instrument from transient
signals from commutation of a nearby tool, connect your
instrument after the filter while keeping other equipment
plugged in before the filter.

Do not put any objects on the top of the filter in order to allow for its normal cooling
Do not install filter in a cluttered situation where it is difficult to observe the filter and to
reach it for a periodic check
Preferably, install filter so that you are be able to see its power LED from a distance
Connecons
The OnFILTER’ CleanSweep®EMI filters come in three basic configurations: with detachable pow-
er cable; with attached power cable; and with terminal blocks.
WARNING
Before attempting any electrical connection, verify that your power source, such as
electrical outlet or junction box, is correctly wired and properly grounded.
Do not use the filter without proper grounding! Failure to properly ground the filter may
result in failure to ground your equipment, in unsafe situation that can cause property dam-
age and injury, as well as failure of the filter to perform.
Filters with Power Cable
WARNING
Use only the power cable supplied with the filter. Other cables that may look very similar to the
one supplied may not have the same voltage/current ratings.
The power cable supplied with the filter has the same type of plug as the outlet on the filter
itself. This simplifies connection of the filter in your facility.
Follow the steps below:
Power down and unplug your equipment
Place filter in the location where it will reside. See above section on location of the filter
If the filter comes with the detachable power cable, connect the cable to the inlet of the
filter
Plug the filter’s cable into the power outlet where your equipment was plugged before. The
green LED on the filter should light up indicating that it receives the power
Plug your equipment into the outlet of the filter and turn it on

Filters with Terminal Blocks
WARNING
This connection requires help of a qualified electrician –if you are not the one, do not attempt
this connection by yourself!
This section is for equipment that is hard-wired to your facility’ power lines. Extreme caution
must be exercised in installation. For connecting wires to the filter you will need wire
strippers and a slot (blade) screwdriver (size depends on
the type of the filter). Plus, you may need other tools
and supplies to connect wires from the filter to your
junction box.
Connecting filter would require additional wires –prepare
adequate lengths of wire of appropriate gauge and
rating. See table below for recommendations on minimum
wire gauge.
Hard-wired equipment may have all of its wires looking the same. Before proceeding any fur-
ther, properly identify every wire in your current connection. Wrong connection can provide live
voltage to ground, swap phase and neutral or reverse the phases –all of this can cause death,
injury and/or severe equipment damage. Prepare labels for every wire of your existing connec-
tion between your equipment and the junction box. Labels should indicate phase, neutral and
ground
Disable power to the junction box, typically by turning off the circuit breaker in your
facility. Verify with proper voltmeter that there is no voltage on the connections
Apply prepared labels to the appropriate wires
Take a photo of the junction box with connection before disconnecting the wires, or draw a
detailed sketch –you will thank yourself for this later
Disconnect wires between your equipment and the junction box
If your equipment is grounded separately from the junction box, disconnect equipment
ground from your facility ground
Place filter in the location where it will reside.
Connect ground wire from your equipment to the output ground terminal of the filter
Strip ~10mm (0.4") of insulation from the ends of the wires for connection to the filter.
Connect the rest of the wires from your equipment to the appropriate terminals at the
output of the filter.
Connect wires to the input terminals of the filter. Tighten connections using screwdriver.
Do not over-tighten the screws.
Label these wires according to the connection of the equipment
Connect other ends of the wires to the appropriate terminals/wires in your junction box.
Refer to your previously-made photo or sketch. Provide necessary insulation to the
newly-made contacts if necessary

Filters with Mounng Flanges
Some models of CleanSweep®filters are equipped with mounting
flanges. The metal enclosure of the filter is electrically connected
to the ground terminal of the filter’s output. In order to preserve
EMI filtering in ground do not place these filters on a metal sur-
face which is electrically connected to the ground of the input
power.
Filter and Circuit Breaker
CleanSweep®filters are equipped with built-in circuit breakers. It is prudent to have typical load
current of no more than 75% of the circuit breaker’ rating to avoid shutdown during occasional
current peaks. Should the current through the filter
exceed filter’s maximum rated current, this circuit
breaker will trigger and disconnect power to your
equipment plugged into the filter. In this case do not
reset the circuit breaker until you unplug equipment
that may contribute to excessive current consumption
and wait a few minutes to let circuit breaker “cool off.”
Circuit breaker can be reset by simply depressing its
actuator until it “clicks.”
