Special Conditions
Electrical ratings:
The rating indicated on the nameplate of the adjustable frequency drive is based on a typical 3-phase line power
supply within the specified voltage, current and temperature ranges, which are expected to be used in most
applications.
The adjustable frequency drives also support other special applications, which affect the electrical ratings of the
adjustable frequency drive.
Special conditions that affect the electrical ratings might be:
• Single phase applications.
• High temperature applications that require derating 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 adjustable frequency drive requires special installation considerations re-
garding:
• Fuses and circuit breakers for overcurrent and short-circuit protection
• Selection of power cables (line power, motor, brake, load sharing 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.
