Basics
CAUTION!
Risks of injury from improper fault clearances!
Improper fault clearances can cause serious personal or property damage.
Therefore:
If components have to be replaced:
To ensure a perfect operation of the controller the following (external) measures have to be taken
additionally:
Place of installation:
The controller should not be installed near to sources of interference generating strong inductive or
capacitive interferences or strong electrostatic fields. Install the external power supply directly beside the
controller to avoid long low voltage wires.
Power supply:
Connect the external power supply to a phase of 230 VAC or 115 VAC which is not used for engines. If not
possible use a galvanic separation over an additional transformer.
Wire installation:
Install all wires for low voltages and encoders always separately from power wires (230 VAC/400 VAC).
Avoid installing these wires close to any contactor or contactor wires.
Fault clearance may only be carried out by qualified and instructed personnel
Prior to the beginning of work provide sufficient room to assemble the
equipment
Please look for cleanliness at the place of installation; loosely around laying
parts and tools are sources of accidents
Look for correct installation of spare parts
All mounting elements have to be assembled correctly
Before resetting please ensure that all covers and protective devices are
installed correctly and function properly
