INFORMATION
For ensuring the isolation and the effectiveness of preventive measures, you have to
perform the checks of the valid and applicable standards (e.g. EN 60204-1 or
EN 61800-5) after any wiring work for installation, conversion, repair, etc.
In order to prevent injury to persons or damage to the plant, check the wiring as des-
cribed below before you connect the voltage supply for the first time:
•
Remove all fieldbus interfaces from the connection module.
•
Disconnect all MOVIMOT
®
inverters from the connection module (only with MFZ.7,
MFZ.8, MFZ.9).
•
Disconnect all plug connectors of the motor connection (hybrid cable) from the
field distributor.
•
Check the insulation of the wiring in accordance with applicable national stand-
ards.
•
Check the grounding.
•
Check the insulation between the supply system cable and the DC 24 V cable.
•
Check the insulation between supply system cable and communication cable.
•
Check the polarity of the DC 24 V cable.
•
Check the polarity of the communication line.
•
Check the mains phase sequence.
•
Ensure equipotential bonding between the fieldbus interfaces.
