7.2 Installation hints
The BUS-2 connection lead must be a shielded lead. The shielding should not be used as 0V
feed lines.
The installation site of the power supply should be as close as possible to the operating unit.
The following table contains the maximum conductor length:

Cable recommendation: JY(St) nx2x0.8Ø
In order to obtain optimum interference immunity, the connections should be as follows:
1.
Insulate lines, separate tracer wires.
2.
Shorten incoming and outgoing BUS lines, in so far as they exist and insert in the
terminals
3.
Use cable ties to fix the cables at the pull reliefs on the mounting plate.
4.
Shorten tracer wire(s) and solder to the shield terminal (soldering tab).
Keep the tracer wires of the shieldings as short as possible when screwing to the
shield terminal of the housing base (for VdS-kit only).
