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.

WARNING: Electrical hazard
Contact with electric components may cause death, even after the unit has been switched off.
Before any interventions on the unit, the network voltage and any other input voltages must be
disconnected for the minimum time indicated in Table 9.
WARNING:
Only connect the electronic drive to Safety Extra Low Voltage circuits (SELV = very low safety
voltage). Circuits intended for use with external communication and control equipment are
designed to ensure insulation from the dangerous adjoining circuits inside the unit. Communication
and control circuits inside the unit are floating in relation to the mass and are classed as SELV.
They must only be connected to other SELV circuits, in order to maintain all the circuits within the
SELV limits and avoid mass loops. The physical and electric separation of the communication and
control circuits from non-SELV electric circuits must be maintained both inside and outside the
inverters.
