2.1 Important installation notes
Safety
regulations
k
The choice of cable material, the installation, and the electrical connection
of the device must conform to the requirements of VDE 0100 "Regulations
on the Installation of Power Circuits with Nominal Voltages below AC
1000 V" or the appropriate local regulations.
k
The electrical connection must only be established by qualified personnel.
k
An isolating switch should be wired between the voltage supply and the de-
vice to be able to disconnect the device from the voltage supply on all
poles prior to accessing the inner parts of the device.
k
Inside the device, safety clearances meet the requirements for double insu-
lation.
When mounting the connection line, ensure that the lines are fitted accord-
ing to regulations and that the safety clearances are maintained.
Electrical sup-
ply types The IPC 300 is suitable for operation with TN and TT supply networks.
h
Carry out installation in accordance with EN 50178.
Fuse protection
k
Fuse protection in accordance with the VDE regulations must be installed
for the voltage supply to the power section. The supply can also be protect-
ed with a circuit breaker in the supply line. This must be dimensioned for
the power consumption of the IPC 300 and the nominal current of the
downstream EMI filter.
k
2 semiconductor fuses are incorporated to protect the IPC 300 in the event
of a ground fault.
(The I
2
t value (operating integral) of the semiconductor fuse must be smaller
than 20000 A
2
s!)
v
Chapter 3.4.3 "Replacing the two semiconductor fuses"
k
If there is a relay in the device (extra code 252), this must be fuse-protected
against the maximum relay current.
Caution!
When working on the device, the voltage supply of the power section must be
switched off on all poles.
Allow 1 minute to elapse after disconnecting, prior to starting work on the de-
vice, since potentially fatal voltages could be present in the device interior and
at the connection terminals.
