Mounting the Mechanism on Pole B
CAUTION
DANGER
36 / 146
The following operations must be repeated when mounting the
operating mechanisms on Pole A and Pole C.
Operating the mechanism when it is not connected to the pole
columns will destroy the operating mechanism.
Therefore:
- Never operate the mechanism without the pole columns.
Place the operating mechanism on a suitable surface in front of the
base frame.
• Check the serial number of the operating mechanism. The serial
number is located on the nameplate on the outside of the door.
• Check to make sure the serial number agrees with the breaker
serial number.
Sudden movements of mechanism elements may lead to serious
personal injury or property damage.
Therefore:
- The operating mechanism must be completely discharged
during installation.
The position indications must be as follows:
Closing spring indication: "Spring discharged"
Mechanism position:
If this is not the case, do not trigger or operate the mechanism
under any circumstance. GE Service must be notified.
The ingress of water (rain) must be prevented at all times. Therefo-
re always protect the operating mechanism from rain during in-
stallation.
Remove the two side panels of the operating mechanism:
a. Remove nuts (5) and tooth lock washers (4)
b. Pull out the bottom of the side panel (2)
c. Remove the side panel by pulling it downwards
Remove the roof (3) of the operating mechanism:
d. Loosen the four bolts (6) on the roof
e. Lift off the roof
Reverse the sequence to reinstall the roof and side panels after
work is completed. Tighten the bolts (6) and nuts (5) to a torque of
17 Nm.
One mounting point in the mechanism is hidden by the spring guard
plate. In order to mount the operating mechanism, proceed as
follows:
• Loosen the two bolts (7) and remove the spring guard plate (8).
The opening latch of the operating mechanism may be immobilized
by a transport lock. The transport lock consists of a cable tie with an
attached identification card.
• Cut through the cable tie and remove the transport lock.
The bolts, washers and nuts for mounting the operating mechanism
are preinstalled on the mechanism.
• Remove the mechanism fasteners - bolts, washers and nuts -
from the mechanism.
