Warning notices concerning the electrical installation

Improper electrical installation can leads to damage of the MultiControl.
4 Only have an electrician undertake electrical installation work.
4 Observe national regulations for the electrical installation. Within the EU, IEC 60204-1 must
be adhered to at a minimum.
4 Before the installation, wiring or removal of the MultiControl, de-energize it and secure it
against inadvertent reactivation.
4 The MultiControl may be operated only with DC voltage with a rated voltage of 24 V and a
maximum permissible deviation of ±5 %.
4 The MultiControl may be operated only with a protected extra-low voltage (PELV according
to IEC 60204-1).
4 Never operate the MultiControl with AC voltage since this will lead to unrepairable damage
to the device.
4 When connecting the MultiControl, observe the correct polarity of the voltage supply.
Reversing the polarity leads to unrepairable damage to the device and the connected
motors.
4 Ensure that no hazardous voltage can come into contact with the connections or the housing,
not even in the event of a malfunction or fault.
4 Place all voltage supplies used on a common ground potential to avoid equalizing currents
via the MultiControl or the bus line.
4 Ensure that the RollerDrive, VDC motors and voltage sources connected with the
MultiControl, as well as the entire conveyor system, are correctly grounded. Incorrect
grounding can result in the build-up of static charge, causing the MultiControl to malfunction
or fail prematurely.
4 Ensure that the existing electrical installation has no interfering effect on the MultiControl.
4 Use only cables that are sufficiently dimensioned for the specific operating conditions.
4 Do not forget to observe the calculations for voltage drop on electrical lines.
4 Observe the regulations for routing cables.
4 Use suitable switching equipment and protective devices to ensure safe operation.
4 Only apply operating voltages when all of the cables have been connected.
4 Do not apply too much tension or load to the plug. When bending the cable at the plug, the
insulation of the cable could be damaged and the MultiControl could fail.
