3.1 Important notes on installation
Safety
regulations
k The choice of cable, the installation and the electrical connection of the
instrument must conform to the requirements of VDE 0100 "Regulations on
the Installation of Power Circuits with Nominal Voltages below 1000 V AC"
or the appropriate local regulations.
k The electrical connection must only be carried out by qualified personnel.
k An isolation switch as per VDE0160/6.3.1 must be wired between the
supply and the converter to be able to disconnect the converter from the
voltage supply prior to starting internal work.
k Inside the converter, safety gaps meet the requirements for double
insulation.
When installing the connecting cable, ensure that the cables are fitted
according to regulations and that the safety gaps are maintained.
Electrical
supply types The IPC 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 protection can also
be achieved by a circuit-breaker in the supply lead. This must be
dimensioned for the power consumption of the power converter and the
rated current of the downstream EMC filter.
k To protect the IPC in the event of a short, additionally provide fuse
protection for the supply lead in the power section by a semiconductor
fuse.

semiconductor fuse for type 70.9050/X1-XX-XXX-XXX-070/XXX.
Provide an appropriate control circuit fuse for control section lead
protection. The control section consumes approx. 50 VA.
3.1.1 Correctly wire all components
EMC filter
V Caution!
The converter has 2 power supplies (to the control section and to the power
section). Disconnect both supplies (all poles) prior to starting work on the
converter.
Allow 1 minute to elapse after switching off prior to starting work on the
converter, since potentially fatal voltages could be present in the converter
interior and at the terminals.

A
The IPC may only be used in conjunction with a suitable filter
(accessories). If a different filter is used, it must be of equal or better
characteristics. Otherwise, inductive voltages may be introduced into
the supply network. We decline any liability for damage caused as a
result.
