Removing from transport pallet (only for frame sizes FX and GX)
During transport, the inverter is fastened on the transport pallet with the aid of two
iron brackets.
WARNING
Note that the center of gravity of the inverter is not in the middle of the unit. When
lifting the pallet, the unit can therefore suddenly change position and swing to the
side.
1. Fasten the hoisting crane cable to the hoisting eyes on the inverter (2 eyes,
see Fig. 2-9 and Fig. 2-10).
2. Remove the two retaining bolts at the top of the front cover.
3. Unscrew the bolts in the iron brackets on the transport pallet and lift the
inverter off the pallet.
4. Once installation has been completed and the inverter connected, fasten the
two retaining bolts for the front cover at the bottom side of the door.
