Application

3.15 Moving the cabinets

3.15.2 Lifting the SINVERT 350 and SINVERT 420 AC cabinet

If the AC cabinet is to be lifted with a crane, a special crane hook must be used, or the crane must be

mounted directly on the transformer.

The AC cabinet housing cannot support the weight of the transformer.

The special hook must be able to lift a weight of 1,800 kg. The fork of the hook must have the right length

(long enough to carry the transformer and short enough so that with the rear panel installed it does not

extend beyond the cabinet). In most cases, the lifting fork must be adjusted to the right length. Do not

remove the rear panel of the cabinet, because you cannot reattach the panel once the cabinet is installed

on-site (direct against the building wall).

Forks completely inserted

underneath

Standard fork is too long

To use the crane hook, proceed as follows:

• Remove the cabinet doors.

• Place rubber mats between hook and transformer so that the cabinet cannot slip from the hook

(metal on metal does not provide sufficient grip).

• Insert the hook directly beneath the transformer (to lift it).

• Attach the cabinet top side to the hook using straps (to prevent tipping).
