Connecting the Supply Cables and Hoses
1568911, Edition 2019-04, Version 0
12.1 Safety Instructions
Qualification of installation personnel
The electrical connection of the pendant system and the Navigator M6
may only be performed by a qualified electrician:
• Observe the safety instructions set out in the Installation Instructions
Part 1 – Ceiling Mount, Chapter "Power Supply".
The gas supply connection of the Navigator M6 may only be performed by
the supplier of the central gas system:
• The supplier of the central gas supply system is responsible for carry-
ing out leak tightness, pressure, flow, contamination and gas type
tests.
Electric shock hazard
Contact with energised components presents a danger to life from electric
shock. Motor-driven, mobile device components can cause injury in the
case of being switched on unintentionally. Prior to any installation and set-
ting up work, the appliance must be disconnected from the mains:
• Disconnect all the poles of the power supply source at the installation
site / appliance and prevent the appliance from being inadvertently
switched back on again.
• Check whether the appliance is de-energised.
• Cover and shield any adjacent energised parts.
Electric shock hazard through defective insulation
The pendant system or the Navigator M6 can be energised if the insulation
is defective:
• Always earth the pendant system and the Navigator M6.
• The power supply and earthing cables must be connected to the strain
relieving mechanisms of the interface plate.
Damaged power cables, gas hoses and compressed air hoses
Damaged power cables can carry an electric voltage of 230V (120V)
which energises the pendant system, and supply gases can escape from
damaged supply hoses:
• Check all cables and hoses for damage. Make sure you carefully insert
them without cables/hoses crossing each other, without loops and
without twisting.
• Lay the cables and hoses in the extension arm and motor arm in such
a way that they are not exposed to tensile stress in any position.
• Cables and hoses must be routed straight upwards out of the flange in
order in order to prevent damage (e.g. rubbing of the sheathing) and
enable their free rotation.
• Protruding cables and hoses must not be placed in the Navigator M6 or
on the flanges, but must be placed on the interface plate and secured
against falling using cable retainers.
• Electric cables must be laid in accordance with regional regulations (in
a spiral coiled tube if required).
