5.3.1 Steps for Cable Connection

1. Ensure that the switch is in the earth position to allow the front cover to be
removed. Each cable box is separated from the others so that work can be carried
out within a single cable box if needed. When the extreme left and right switches
are earthed the outside cable box plates can be removed.
2. Where the centre switch and one of the outside switches are turned to the earth
position (for example during commissioning) the side plate between the two cable
boxes can be removed to give more working space.

5.4 Fuse Types and Replacement

The fuses used must comply with IEC 60282-1:1994 (High-voltage fuses - Part 1:
Current-limiting fuses) having a medium striker energy of 1J ± ½J. It is important that
care is taken with the fuse alignment when installing small diameter fuses (ie less than
87mm). The fuse canister is completely sealed to IP65.
To replace a fuse, undertake the steps outlined in Section 2.3 on page 8. This section
also details the switch-fuse reset procedure. Note that the switch will not remain in the
closed position if a blown fuse is present.
Auxiliary switches are available to give an additional indication of the fuse trip status.
Avoid dirt on the rubber plug; do not apply grease. The fuse canister and tripping
mechanism must be kept clean and dry.
Discard and replace all three fuses when any fuse has operated (refer to IEC 60282-1 &
IEC 60420).
