Before switching on the inverter go through the following checklist.
Is the inverter firmly bolted in the control cabinet?
Is there enough space to ensure sufficient air circulation?
Are mains and motor cables as well as the control cables installed
separately from each other?
Are the inverters connected to the correct supply voltage?
Are all mass and earthing cables attached and well contacted?
Ensure that mains and motor cables are not interchanged as that
will lead to the destruction of the inverter!
Is the motor connected in-phase?
Check tacho, initiator and encoder for firm attachment and correct
connection!
Check, whether all power and control cables are firmly in place!
Remove any tools from the control cabinet!
Attach all covers and protective caps to ensure that all live parts
are secured against direct contact.
When using measuring instruments or computers an isolating
transformer should be used, if not, make sure that the equipotenial
bonding between the supply lines is guaranteed!
Open the control release of the inverter to avoid the unintended
starting of the machine.
