Control cables
External volt free contacts must be suitable for switching < 10 VDC.
NOTICE:
• Install the control cables separate from the power supply cables and the fault signal
relay cable
• If the control cables are installed in parallel with the power supply cable or the fault
signal relay, the distance between the cables must exceed 200 mm
Do not intersect the power supply cables; should this be necessary, a 90° intersection
angle is permitted.
