WARNING
Power and motor connections
A fixed location, non varying connection is necessary because of a leakage current
> 3.5 mA.
The inverter must always be grounded. If it is not grounded correctly, extremely dangerous
conditions may arise which could prove potentially fatal.
Isolate the mains electrical supply before making or changing connections to the unit.
The terminals of the Inverter can carry dangerous voltages even if the inverter is
inoperative. Wait at least 5 minutes to allow the unit to discharge after switching off the line
supply before carrying out any installation work.
When connecting the line supply to the inverter, make sure that the terminal case of the
motor is closed.
When changing from the ON to OFF-state of an operation if an LED or other similar display
is not lit or active; this does not indicate that the unit is switched-off or powered-down.
Ensure that the inverter is configured for the correct supply voltage – it must not be
connected to a higher voltage supply.
WARNING
Filtered drives can only be used on power systems with grounded starpoint.
