Mounting steps
How to connect the filter:
1. De−energise the control cabinet and fuse it against re−energisation.
2. Wait for at least 3 minutes before checking the standard device for isolation from
supply.
3. Wire the filter input cables and the filter output cables according to the connection
plan.
– Observe tightening torque.
4. Wire the DC−bus cables (+UG/−UG) according to the connection plan.
– The terminals +UG und −UG must be connected using the same cable cross−section
as in the motor cable.
– Observe tightening torque.
Only for types with thermal contact:
5. Wire the terminals of the thermal contact 3.
– Integrate the thermal contact into the monitoring system so that the mains
supply is switched off when the filter is overheated.
– NC contact, switching capacity: 250 V AC / 1.6 A
– Connect the twisted cables.
– Observe tightening torque.
) Note!
When commissioning, please observe that operation is only permissible

ƒ at a switching frequency of 8 ... 16 kHz
Ensure that the automatic switching frequency reduction is deactivated (see
documentation of the standard device). The filter will overheat at a switching
frequency of <8 kHz.
