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.

Before Commencing Repair Work
WARNING
Hazardous Voltage
Disconnect the frequency converter from mains
Disconnect DC bus terminals 88 and 89
Wait at least the time mentioned in section General Warning above
Remove motor cable
Failure to follow recommendations could result in death or serious injury.
Special Conditions
IT Mains
WARNING
400 V units with RFI filters may not be connected to mains supplies in which the voltage between phase and earth is
more than 300 V, Please note that for the IT mains and delta earth, mains voltage may exceed 300 V between phase
and earth. Units with type code R5 can be connected to mains supplies with up to 400 V between phase and earth.
Failure to follow recommendations could result in death or serious injury.
