5.3. General notes on wiring
The selection of the correct cable types is important for the reliable power distribution, control and monitoring by
means of a
PowerPlex
®
system. Please ensure to use cables of superior quality with the suitable cross sections
to avoid voltage drops. Please also so the separate chapter 0 concerning the integration of the device into the
CAN bus network.
The cables should be laid very carefully to achieve the maximum performance of the
PowerPlex
®
installation.
Table 8 gives general hints which must be observed regarding wiring of a PowerPlex
®
system and the connected
loads.
Item Note
1 The cables should not be kinked or bent sharply. Please provide sufficient bending radii.
2
Cables must be protected against damages and heat. Avoid the proximity to moveable or hot parts and
to machines.
3
Cables should be secured by means of brackets or cable clips. Excessive cable lengths should be
disposed of appropriately.
4 Depending on the site of the cables, waterproof bushings might be useful.
5 Ensure a suitable strain relief.
6 Check cables about intact insulation, above all after cable laying.
Table 8: General notes on wiring
If AC and DC current is used for installation, an adequate insulation must be ensured.
Note
Please do not forget the 120 Ω terminating resistor when the
PowerPlex
®
Mini Module is connected
as first and/or last participant on the CAN bus.
