Use the tightening torques specified in
Insert each inverter module into the cubicle as follows:
(1) Move the inverter module close to the ramp, then retract the support legs of the module.
(2) Push the module back into the cubicle – mind your fingers.
(3) Refasten the module fixing screws at the top, reconnect the DC busbars.
