6.2.5 Note on routing of wiring in housings
This figure shows the routing of wiring for the transmission system inside a panel housing:
To comply with the requirement of the Low-Voltage Directive, the supply line for
the 230 V supply voltage for the power unit
mustonly
be routed inside the cross-
hatched area. In addition, this line
must
be protected against cable breakage and
contact with other system components under mains voltage, e.g. using a cable tie.
The low-voltage wiring must be designed to prevent any contact with the supply
voltage under any circumstances in the event of line breakage or slippage (e.g.
using cable ties).
Provide the power supply for the 4G IP USB extension module via the U ext 1
connection (external consumer) of the power supply unit used.
