FUSE SUBSTITUTION PROCEDURE
- Undo the cover fastening screw (1)
- Remove the cover following the movement indicated by
the arrow (2)
- In this way the fuse is discovered (3)
- Slacken the two bolts fixing the fuse in place with a No.19
spanner (GFW 500/600A) or a No.17 spanner (GFW 400A).
There is no need to remove the bolts, as the fuse is pulled
out of its housing as shown by the arrows (5).
- Insert the new fuse as indicated by the arrows (6)
WARNING: the washer must be between the bolt and the
copper strap (NOT under the fuse).
- Tighten the two nuts with a No. 19 spanner (GFW 500/600A)
or a No. 17 spanner (GFW 400A), to a torque of 12 Nm.
- Put the cover back in place, pinning down the top part first
(be careful to hook it on the tooth as shown in the figure).
- Fasten the cover by the specific screw in side (1)
