8 Commissioning - Operation
8.1
Precautions to be taken before commissioning
The internal electrical connecĆ
tions as well as the adjustĆ
ments to the control mechanism
are carried out at the factory and
cannot be modified.
Ensure that the supply voltaĆ
ges for the motor and the
electromagnets truly correspond to
the normal voltages foreseen on
the terminals of these elements.
The characteristics are shown
on the rating plate for the
BLR control mechanism.
8.2
Electrical connection of the BLR control mechanism
For control mechanisms with a
longitudinal layout, drill the
sheet metal located in the lower
part of the mechanism to allow
for cable entry, and fit a wire
sleeve or a cable gland in the
opening.
Drill hole with
wire-sleeve
For front layout mechanisms
(front panel), this operation is
unnecessary.
Next, ensure the wiring passes
through the rough cut on the
protection cover.

front layout
Rough cut for
longitudinal
layout
Carry out the electrical
connections from the numbered
terminal plates whilst respecting
the diagram supplied with the
mechanism.
8.3
Testing the operation of the circuit breaker
Ensure that the filling presĆ
sure has been adjusted if the
circuit breaker was shipped by air.
Carry out several opening and cloĆ
sing operations on the circuit breaĆ
ker with the manual (and electrical)
controls in order to ensure it
functions correctly (see § 3).
In the case of a control
mechanism equipped with an
undervoltage coil (MIA), do not
forget to supply power to this coil
before any closing test.
8.4
Operation of the circuit breaker
See the instructions in the
AMTNoT017-02 manual.
