2.1.4 Special Conditions
Electrical ratings:
The rating indicated on the nameplate of the active filter is
based on a typical 3-phase line power supply, within the
specified voltage, current and temperature range, which is
expected to be used in most applications.
The unit also supports other special applications, which
affect the electrical ratings of the filter. Special conditions
that 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 overcurrent and
short-circuit protection
•
Selection of power cables (line power 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 line power, the
device can be started/stopped using digital commands,
bus commands, references or via the Local Control Panel.
•
Disconnect the unit from line power 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 Line Power
NOTE!
IT line power
Do not connect the unit with RFI filters to line power
supplies with a voltage between phase and ground of
more than 440V for 400V.
For 400V IT line power and delta ground (grounded leg),
AC line voltage may exceed 440V between phase and
ground.
14-50 RFI Filter
can be used to disconnect the internal RFI
capacitors from the RFI filter to ground.
2.1.7 Disposal Instructions
Equipment containing electrical components
may 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.
