Safety

Before Commencing Repair Work

WARNING
Hazardous Voltage!
1. Disconnect the frequency converter from mains
2. Disconnect DC bus terminals 88 and 89
3. Wait at least the time mentioned in section General Warning above
4. Remove motor cable
Failure to follow recommendations could result in death or serious injury.

Special Conditions

Electrical ratings:
The rating indicated on the nameplate of the frequency converter is based on a typical 3-phase mains power
supply, within the specified voltage, current and temperature range, which is expected to be used in most ap-
plications.
The frequency converters also support other special applications, which affect the electrical ratings of the fre-
quency converter.
Special conditions which affect the electrical ratings might be:
• Single phase applications
• High temperature applications which require de-rating of the electrical ratings
• Marine applications with more severe environmental conditions.
Other applications might also affect the electrical ratings.
Consult the relevant sections in this manual and in the for information about the electrical ratings.
Installation requirements:
The overall electrical safety of the frequency converter requires special installation considerations regarding:
• Fuses and circuit breakers for over-current and short-circuit protection
• Selection of power cables (mains, motor, brake, loadsharing and relay)
• Grid configuration (grounded delta transformer leg, IT,TN, etc.)
• Safety of low-voltage ports (PELV conditions).
Consult the relevant clauses in these instructions and in the for information about the installation requirements.

IT Mains

WARNING
Do not connect frequency converters with RFI-filters to mains supplies with a voltage between phase and earth of
more than 440 V for 400 V converters and 760 V for 690 V converters.
For 400 V IT mains and delta earth (grounded leg), mains voltage may exceed 440 V between phase and earth.
For 690 V IT mains and delta earth (grounded leg), mains voltage may exceed 760 V between phase and earth.
Failure to follow recommendations could result in death or serious injury.
par.14-50 RFI Filter can be used to disconnect the internal RFI capacitors from the RFI filter to ground.
