Trane TR200 Operating Instructions Manual page 6

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 TR200 Design Guide 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 TR200 Design Guide for information about the installation
requirements.
