Mounting the 35 mm² ring terminals on the copper bar side
Fig. 4-19: HV BM 1.2, mounting the ring terminals on the copper bar side
"
Mount the ring terminals on the copper bar in the usual manner.
WARNING!
The nuts and the ring terminals may not extend over the threaded bolts,
otherwise the distance to the cover may be too small. There is then a risk
of short circuits and the hazard of life threatening electric shocks.
"
Only use the nuts and ring terminals supplied.
"
If other components are applied, only use combinations of nuts and
ring terminals that do not extend over the threaded bolt. Also, make
sure that only nuts with standard dimensions are used.
WARNING!
The ring terminals must not touch each other or the housing during ope-
ration, otherwise there is a risk of life-threatening electric shocks and
short circuits. Also, the contact resistance between the nuts and the ring
terminators needs to be minimized.
"
Tighten the nuts applying the above-mentioned torque so that
the terminals are securely fixed during operation and the contact
resistance between nuts and terminals is sufficiently low.
"
Make sure that there is sufficient clearance between the ring terminals
and the housing and between the ring terminals (at least 3 mm).
