The unit also supports other special applications, which
affect the electrical ratings of the filter. Special conditions
which affect the electrical ratings might be:
•
High temperature applications which require
derating of the electrical ratings
•
High altitude installation which require derating
of the electrical ratings
•
Marine applications with more severe environ-
mental conditions
Consult the relevant clauses in these instructions for
information about the electrical ratings.
Installation requirements:
The overall electrical safety of the active filter requires
special installation considerations regarding:
•
Fuses and circuit breakers for over-current and
short-circuit protection
•
Selection of power cables (mains and relays)
•
Grid configuration (IT,TN, grounded leg, etc.)
•
Safety of low-voltage terminals (PELV conditions)
Consult the relevant clauses in these instructions for
information about the installation requirements.
2.1.5 Avoid Unintended Start
NOTE
While the Active Filter is connected to mains, the device
can be started/stopped using digital commands, bus
commands, references or via the Local Control Panel.
•
Disconnect the unit 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.
2.1.6 IT Mains
NOTE
IT mains
Do not connect the unit with RFI-filters to mains supplies
with a voltage between phase and earth of more than
440V for 400V.
For 400V IT mains and delta earth (grounded leg), mains
voltage may exceed 440V between phase and earth.
14-50 RFI Filter
can be used to disconnect the internal RFI
capacitors from the RFI filter to ground.
2.1.7 Disposal Instruction
Equipment containing electrical components
must not be disposed of together with domestic
waste.
It must be separately collected with electrical
and electronic waste according to local and
currently valid legislation.
