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 refer to the separate chapter on integrating the device into the CAN bus
network.
The cables should be laid very carefully to achieve the maximum performance of the PowerPlex
®
installation.
Table 7 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 7: General notes on wiring
If AC and DC current is used for installation, an adequate insulation must be ensured.
Information
Please do not forget the 120 Ω terminating resistor when the PowerPlex
®
Web Server is connected
as first and/or last participant on the CAN bus.
