Important Safety Information 1

Section 1: Important Safety Information

This option is specifically designed to be used with the VFD variable speed drive product range and is

intended for professional incorporation into complete equipment or systems. If installed incorrectly, it

may present a safety hazard. The VFD uses high voltages and currents, carries a high level of stored

electrical energy, and is used to control mechanical plants, which may cause injury. Close attention to

system design and electrical installation is required to avoid hazards during normal operation or in the

event of an equipment malfunction. VFDs and its options should be installed only by qualified electrical

personnel and in accordance with local and national regulations and codes of practice.

WARNING

Electric shock hazard!

Disconnect and ISOLATE the VFD before attempting any work on it. High voltages are present at the

terminals and within the drive for up to 10 minutes after the disconnection of the electrical supply.

Wait until 10 minutes have elapsed after turning off the power supply before disconnecting the plug

that supplies power to the drive.

It is the responsibility of the installer to ensure that the equipment or system into which the product is

incorporated complies with the EMC legislation of the country of use. Within the European Union,

equipment into which this product is incorporated must comply with 2004/108/EC, Electromagnetic

Compatibility.

Within the European Union, all machinery in which this product is used must comply with the Directive

98/37/EC, Safety of Machinery. In particular, the equipment should comply with EN60204-1.

The manufacturer accepts no liability for any consequences resulting from inappropriate, negligent, or

incorrect installation.

The contents of this installation guide are believed to be correct at the time of printing. In the interests

of a commitment to a policy of continuous improvement, the manufacturer reserves the right to

change the specification of the product or its performance or the contents of this installation guide

without notice.

Input Line Chokes 2

Section 2: Input Line Chokes

2.1 Using Input Chokes

Input chokes help to protect the VFD from spikes on the incoming power supply, as well as reducing

input harmonic currents. It is recommended that an input choke is used under the following

circumstances:

•On all 600 Volt Size 2 and 3 VFDs

•On all applications where the incoming power supply uses a sliding busbar or brush-gear-type

arrangement (e.g. commonly used on overhead cranes)

•On all installations where the supply impedance is low or the fault current is very high

•On all installations where the incoming power supply is prone to spikes, dips notches, or other

disturbances

Typically, the input choke will provide a significant reduction in harmonic distortion on the incoming

power supply, and will reduce the overall current into the drive cover and back pages.

Output Line Chokes 5

Section 3: Output Line Chokes

3.1 Using Output Chokes

AC Inverters use a fast switching pulse width modulation (PWM) technique to create a variable

frequency AC Output to the connected motor. The fast switching of the output of the drive when

connected with long motor cables results in a reflected voltage at the motor which can be up to three

times the AC supply voltage, with a very fast rise time. Output chokes help to reduce this peak voltage,

and increase the rise time, to reduce the stress applied to the motor insulation and prevent damage.

Output chokes are recommended whenever any of the following conditions are met:

•The connected motor is not known to be suitable for use with a PWM output Inverter (as

confirmed with the motor manufacturer)

•The motor cable length exceeds the maximum permissible motor cable length stated for the

product in the relevant user manual

oSpecified cable lengths apply to standard type copper shielded cable only

oFor unshielded cables, the maximum length may increase by 50%

oUsing a choke allows the maximum cable length to increase by 100%

•High capacitance motor cable is used, e.g. typically fire-resistant cables
