2.1.5 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 applications.
The frequency converters also support other special applications, which affect the electrical ratings of the frequency 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.
2.1.6 Caution
The frequency converter's DC link capacitors remain charged after power has been disconnected. To avoid an electrical shock hazard,
disconnect the frequency converter from the mains before carrying out maintenance. Before doing service on the frequency converter,
wait at least the amount of time indicated below:
Voltage Power size Min. Waiting Time
380 - 480 V 110 - 250 kW 20 minutes
Be aware that there may be high voltage on the DC link even when the LEDs are turned off.
