If the current bars are rather inflexible it is recommended to use an addition-
al angled bar. This way it is possible to compensate mechanical tolerances
between the mounting platform for the lower module and the current bars in
all 3 axes.
Electrical installation of
the earth terminal
Connect the earthing cable to the earth terminal with the appropriate screw.
Schaltbau strongly recommends a Schnorr-Washer (or similar) to secure the
screw.
Commissioning
After installation the following checks are recommended:
a)
Check the protective earth
b)
Check the main connections
c)
Check the control connections
d)
Check the latching and locking between Upper and Lower Module
e)
Check that both protection covers are fitted
f)
Several activation and deactivation operations of the contactor with-
out the main circuit active
g)
Check the function of the auxiliary contacts
The use of press nuts in the current bars will simplify installa-
tion and maintenance.
