and discharge the closing spings.
AVERTISSEMENT: Avant d’installer tout accessoire,
mettre le disjoncteur en position OFF, le déconnecter
de toute tension d’alimentation, et décharger les
resorts d’armement
Back Connected Terminations Assembly (3 Pole)
Procedure:
1. Turn the breaker off and discharge the closing
springs by depressing the OFF and ON buttons in
the sequence OFF-ON-OFF. Verify that the
breaker OFF-ON indicator shows OFF on a green
background and that the charge indicator shows
DISCHARGE on a white background.
2. First assemble & orient the middle terminations
assemblies on to the breaker rear terminals as
shown in Fig A.
3. Middle top & bottom terminal assemblies to be
tightened with M12 hardware’s as shown in Fig A,
to 80 Nm (59 ft-lbs) torque.
4. Assemble the heat sinks LH & RH with spacers
introduced in between the multiple pads of
terminal assemblies as shown in Fig B for bottom
& top sides. Tightened them with M8 mounting
hardware’s to 16 Nm (11.8 ft-lbs) torque.
5. Assemble the outer terminal assemblies on
bottom and top side with M12 hardware
tightened to 80 Nm (59 ft-lbs) torque as shown in
Fig C.
6. Assemble the heat sinks RH with clearance holes
& spacers introduced in between the multiple
pads of outer terminal assemblies as shown in fig
D, for bottom & top sides and tightened them
with M8 mounting hardware’s to 16 Nm (11.8 ftlbs) torque.

7. Assemble remaining terminal assemblies similarly
on all poles so as to populate as 3pole / 4 pole
breaker.

Procedure:
1. Similar Procedure to be followed for 4 pole
breaker with neutral on right or left.
2. For 4 Pole breaker, assemble the L2 pole with
two heat sinks first. Then assemble the
adjacent poles with only one outer heat sinks.
