7.1.3 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.
