Warning notices for electrical installation
Caution
Risk of injury when working on electrical equipment!
¾
Electrical work should only be performed by qualified and authorised persons.
¾
Before installing, removing or connecting the ZoneControl, switch off 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 ground potential in order to avoid compensating currents via
the ZoneControl.
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 ZoneControl.
¾
Ensure that current load at each terminal or terminal block does not exceed 10 A.
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 ZoneControl.
¾
Observe national regulations for electrical installation.
¾
Only operate the ZoneControl with a protective extra-low voltage (PELV) of 24 V or 48 V.
¾
Never operate the ZoneControl 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 influence on the ZoneControl.
¾
Only use cables that are adequately dimensioned for the specific 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 ZoneControl to fail.
¾
Only use the specified mating plug (see „Inputs and outputs”, page 30) and the spare tool supplied.
¾
Ensure that the ZoneControl is not reverse connected. The ZoneControl will be damaged beyond repair
when power is applied if the ZoneControl is reverse connected and there is a peer-to-peer connection.
