Replace the ceramic protection insert
Depending on the contactor type, see Fig. 59 to Fig. 62.
The ceramic protection have to be replaced only in case
of apparent wear and tear or damage.
In some older contactor versions the ce-
ramic protection inserts could be xed
with glue. In this case:
X Cut the glue at the old ceramic pro-
tection insert (4) carefully with a
sharp knife and pry it open.
X Remove all residues of old glue.
X Remove the old ceramic protection inserts (4) one
by one.
X Place the new ceramic protection inserts (4) in the
correct position and push them against the plastic
guidance.
The ceramic protection inserts must be in-line
with the plastic surface without projecting length.
