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:
•
High temperature applications which require de-
rating of the electrical ratings
•
Marine applications with more severe environ-
mental conditions.
Other applications might also affect the electrical ratings.
Consult the relevant sections in this manual and in the
AF-600 FP 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
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 AF-600 FP Design Guide for information about the
installation requirements.
2.1.6 Installation at High Altitudes (PELV)
NOTE
Installation at high altitude:
380 - 480 V: At altitudes above 3 km, please contact GE
regarding PELV.
525 - 600 V: At altitudes above 2 km, please contact GE
regarding PELV.
2.1.7 Avoid Unintended Start
WARNING
While the frequency converter is connected to mains, the
motor can be started/stopped using digital commands, bus
commands, references or via the keypad.
•
Disconnect the frequency converter from mains
whenever personal safety considerations make it
necessary to avoid unintended start.
•
To avoid unintended start, always activate the
[OFF] key before changing parameters.
•
An electronic fault, temporary overload, a fault in
the mains supply, or lost motor connection may
cause a stopped motor to start.
2.1.8 IT Mains
WARNING
IT mains
Do not connect frequency converters with option factory
installed A1/B1 RFI filters to mains supplies with a voltage
between phase and earth of more than 440 V for 400 V.
For 400 V IT mains and delta earth (grounded leg), mains
voltage may exceed 440 V between phase and earth.
SP-50 RFI Filter
can be used to disconnect the internal RFI
capacitors from the RFI filter to ground.
