Matters That Require Attention

1. Elevated Operating Temperature:If installed in a closed or

m ulti-unit rack assembly, the operating ambient temperature of

the rack environment m ay be greater than room temperature.

Therefore, consideration should be given to installing the

equipment in an environment compatible with the maximum

am bient temperature (Tm a) specified by the manufacturer.

NOTE

In order to ensure reliable operations, please make sure the

operating temp

erature

of the environment does not exceed the

spec. When moun

ting a rack-mo unted s witch with other

operating units in a cabinet without forced ve ntilation, it is

recommended that 1U of space is reserved between each rack

m ounted switch and/or device.

2. Required Air Flow: Installation of the equipment in a rack should

be such that the amount of air flow required for safe operation of

the equipment is not compromised.

NOTE

The optimal keep-out zone is 50 mm for the top, bottom, left,

and right side of the device.

3. Mechanical Loading: Mounting of the equipment in the rack

should be such that a hazardous condition is not achieved due to

uneven mechanical loading.

4. Circuit Overloading: Consideration should be given to the

connection of the equipment to the supply circuit and the effect

that overloading of the circuits might have on overcurrent

protection and supply wiring. Appropriate consideration of

equipment nameplate ratings should be used when addressing this

concern.

5. Reliable Grounding: Reliable grounding of rack-mounted

equipment should be maintained. Particular atte ntion should be

given to supply connections other than direct connections to the

branch circuit (e.g. use of power strips).

ATTENTION

Safety First

Be sure to disconnect the power cord

before installing and/or

wiring your Ethernet Switch. Calculate the m aximum possible

current in each power wire and common wire. Observe all

electrical codes dictating the maximum current allowable for

each wire size. If the current goes above the maximum ratings,

the wiring could overheat,

which can cause serious damage to

your equipment.

Connecting the Power Inputs

The MDS-G4000 and MDS-G4000-L3 Series s upp ort 4 types of power

supply:

•PWR-HV-P48: one 110/220 VAC/VDC (90 to 264 VAC, 88 to 300

VDC), o ne 48 VDC PoE power input for PoE+ ports.

•PWR-LV-P48: one 24/48 VDC (18 to 72 VDC), one 48 VDC PoE

power input for PoE+ ports.

NOTE

The required power module depends on the choice of LM-7000H

m odule. Refe r to the following power/module combination

requirements.

•

LM-7000H non-PoE modules:

Any po we r m odule

•

LM-7000H PoE modules:

PWR-HV-P48, PWR-LV-P48 only

NOTE

The PWR

-LV-P48 power m odule is certified for Hazardous

Location use.

•PWR-HV-NP: one 110/220 VAC/VDC (90 to 264 VAC, 88 to 300

VDC) power input.

•PWR-LV-NP: one 24/48 VDC (18 to 72 VDC) power input.

For the PWR-HV-P48, the 110/220 VAC/VDC power supplies provide

power to the switch. Separate 48 VDC power supplies are required to

provide power to all PoE+ ports (50 to 57 VDC is recommended for

IEEE 802.3at devices. The max. PoE output from an external power

supply is 720 W when the operating temperature is under 60°C; 360 W

when the operating temperature is under 75°C.).

For the PWR-LV-P48 m odels, the 24/48 VDC power supplies provide

power to the switch. Separate 48 VDC power supplies are required to

provide power to all PoE+ ports (50 to 57 VDC is recommended for

IEEE 802.3at devices. The max. PoE output from an external power

supply is 720 W when the operating temperature is under 60°C; 360 W

when the operating temperature is under 75°C.).

ATTENTION

or Hazardous Location Use

The

PoE capacity of the PWR-LV-P48 is only certified for use in

azardous locations up to a maximum power budget of 369.6

W and a m axim um o utput o f up to 15.4 W per port.

For the PWR-HV-NP, the 110/220 VAC/VDC power supplies provide

power to the switch.

For the PWR-LV-NP, the 24/48 VDC power supplies provide power to

the switch.

Power Terminal Blocks

The connection for power input and PoE external power supply is on the

power modules.

PWR-HV-P48/PW R-HV-NP

1. Insert the neutral/line (L/N/Ground) AC wires into the terminals.

2. Insert the terminal block connector into the terminal block

receptor.

PWR-LV-P48/PWR-LV-NP

1. Rem ove 8 to 9 mm of the DC wires ’ protective cover.

2. Use a tool to push the spring mechanism inwards to open it.

3. Inse rt the negative/positive (-/+) DC wires into the terminals.

4. Release the spring mechanism.

5. Insert the terminal block connector prongs into the terminal block

receptor.

PoE Power Terminal Blocks

1. Rem ove 8 to 9 m m of the DC wire s’ protective cover.

2. Use a tool to push the spring mechanism inwards to open it.

3. Insert the negative/positive (-/+) DC wires into the terminals.

4. Release the spring mechanism.

5. Inse rt the terminal block connector prongs into the terminal block

receptor.

NOTE

In order to have higher levels of protection against surge, it is

suggested to install a

surge protector in front of the power

input

of the PoE powered device so that it is suitable for use in

IEC 61850 conditions.

NOTE

When wiring the power input, we suggest using the cable type -

AWG (Am erican Wire Gauge) 1

6-20 (1.31-0.519 mm2

) and the

corresponding pin type cable te rminals. The rated temperature

of wiring should be at least 105°C.

NOTE

When wiring the

PoE power input, we suggest using the cable

type

- AWG (Am erican Wire Gauge) 16 (1.31 mm2) and the

corresponding pin type cable te rminals. The rated temperature

of wiring should be at least 105°C.

NOTE

When two power units are installed on the switch, both power

units will be activated simultaneously, which will enable power

redundancy.

NOTE

The reve rse power input connection will not activate the device

or PoE input

. In addition, the PoE will only activate when the

external power supply is installed on the same power unit.

Wiring the Relay Contact

Each power module has one relay output that can provide two types of

relay output. Refer to the table below for detailed information.

The relay contact is used to detect user-configured events. Two wire s

are attached to the relay pins with normally close and normally o pen

options.

1. Rem ove 8 to 9 m m of the DC wires’ protective cover.

2. Use a tool to push the spring mechanism inwards to open it.

3. Inse rt the wires into the terminals.

4. Release the spring mechanism.

5. Inse rt the terminal block connector prongs into the terminal block

receptor.
