Depending on the number of fuse-links and their rated currents it may be necessary that a
contactor truck is equipped with a mechanical closing latch. Contactor trucks
with
mechanical closing latch have no corresponding label. Contactor trucks versions
without
mechanical closing latch are labelled accordingly on the front side:
Fig. 330: Instruction label on the front side of the truck
First, check if the panel requires a contactor truck with / without mechanical closing latch to
be inserted. Second, check the front side of the contactor truck for the according label.
Preparing the operating shaft for the feeder earthing switch
Make sure that the coupling pin of the operating shaft for the feeder earthing switch at the
contactor truck and the coupling in the switching-device compartment are in vertical position.
