Guidelines for planning the electrical installation 85

Residual current device compatibility
The drive is suitable to be used with residual current devices of Type B.
Note : The EMC filter of the drive includes capacitors connected between the main circuit
and the frame. These capacitors and long motor cables increase the ground leakage
current and may cause fault current circuit breakers to function.
Implementing the emergency stop function
The drive can be equipped with a category 0 and 1 emergency stop function (option
+Q951, +Q952, +Q963, +Q964, +Q978 or +Q979). For safety reasons, install the
emergency stop devices at each operator control station and at other operating stations
where emergency stop may be needed.
Note : Pressing the stop key on the control panel of the drive, or turning the operating
switch of the drive from position “1” to “0” does not generate an emergency stop of the
motor or separate the drive from dangerous potential.
See the appropriate user’s manual for the wiring, start-up and operation instructions.
Implementing the Safe torque off function
See chapter The Safe torque off function (page 223 ).
Implementing the Prevention of unexpected start-up
function
The drive can be equipped with a Prevention of unexpected start-up (POUS) function
either with an FSO-xx safety functions module (Q950) or with a safety relay
(Q957). The POUS function enables short-time maintenance work (like cleaning)
on the non-electrical parts of the machinery without switching off and disconnecting the
drive.
See the appropriate user’s manual for the wiring, start-up and operation instructions.
