Checklist prior to
Start-up
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.
