5.3 Warning notices for electrical installation
CAUTION
Risk of injury when working on electrical equipment.
¾ Electrical installation work must only be carried out by a qualied electrician.
¾ Before installing, removing or connecting the MultiControl, switch o the power to the conveyor system and
ensure that it cannot be unintentionally switched on again.
¾ Set all the power supplies used to the same earth potential in order to avoid compensating currents via the
MultiControl or bus cable.
¾ Ensure all components are earthed correctly. Improper earthing can lead to a build-up of static charge,
which can result in a fault or premature failure of the MultiControl.
¾ Ensure that suitable switching devices and protective systems are in place that will allow the equipment to be
operated safely.
¾ Only switch on the operating voltages when all cables are connected.
NOTE
Improper electrical installation can result in damage to the MultiControl.
¾ Observe national regulations for electrical installation.
¾ Only operate the MultiControl with a protective extra-low voltage (PELV) of 24 V or 48 V.
¾ Never operate the MultiControl with an alternating voltage.
¾ Ensure that the polarity of the power supply is correct.
¾ Ensure that the existing electrical installation has no disruptive inuence on the MultiControl.
¾ Only use cables that are adequately dimensioned for the specic operating conditions.
¾ Ensure that the calculations for the drop in voltage in the cables are taken into account.
¾ Observe regulations for laying cables.
¾ Do not expose the connectors to excessively high tensile or pressure loads. If the connector cable is bent, this
can damage the cable insulation and cause the MultiControl to fail.
