♦ Connecting control lines of optional modules (in preparation)
NOTE
When installed, control lines must be shielded and isolated from the power cables, laying them at a minimum
distance of 20 cm. The shield must be connected on both sides. On the unit's housing, the shield is connected
with shield clamps. Handling of these clamps is shown in Figure 3.3.
When they intersect, control and power cables must be laid at an angle of 90°.
