(1195C-N4 -- (2) N.O. / N.C. 5 VDC 10mA)
(1195C-N5 -- (1) N.O. / N.C. and 1 N.O. / Late Break N.C.)
(For use on DC input coils only - 125 VDC maximum)

(For use on DC input coils only - 250 VDC maximum)
ATTENTION: To prevent electrical shock, disconnect from power source before installing or servicing.
Auxiliary Contact Replacement
1. Disconnect all power cables (or bus work) and all control wiring to the contactor.
2. Remove the contactor from its mounted location. The contactor is best serviced in the tabletop position.
3. Disconnect the coil wire leads from the Auxiliary (Figure 2B).
4. Remove the cover attachment hardware from the contactor and remove the cover (Figure 1).

5. Remove the Auxiliary from the contactor by first rotating the retainer to release the top of the Auxiliary. Then pull out
the top of the Auxiliary (the tab must clear the notch) and then push Auxiliary slightly downward to release lower tab
that holds the Auxiliary to the housing (Figures 2A & 2B).

Auxiliary Contact Installation (200A)
1. Insert the lower tab into the recess on the side of the contactor base. With proper installation, the Actuator will fit
into the hole in the slot in the side of the contactor housing (Figure 3A). Using a thin rod or flat blade, lift the Actuator
up as necessary to insert it into the slot mentioned (Figures 3A & 3B). Rotate the Retainer (if not attached to cover)
to its original position, which will slide over the upper tab.

2. Reinstall the cover and secure it with the original mounting hardware. NOTE: Cover must fit under metal bracket
on the Control-Pak. Tighten the four screws in a diagonal pattern to 5 lb-inches (Figure 1).
3. Reattach the coil wire leads and any auxiliary control wires to the Auxiliary (tighten to 7 - 9 lb-inches).
4. Reinstall the contactor. Torque mounting screws to 50 - 75 lb-inches.
5. Reconnect the line and load conductors and tighten the main terminal hardware and bolts to 125 - 145 lb-inches.
Auxiliary Contact Installation (400A and 600A)
1. Rotate the Retainer upwards.
2. Insert the lower tab into the recess on the side of the contactor base. With proper installation, the Actuator will fit
into the hole in the slot in the side of the contactor housing (Figure 4A). Using a thin rod or flat blade, lift the Actuator
up as necessary to insert it into the slot mentioned. Rotate the Retainer to its original position, which will slide over
the upper tab (Figures 4A & 4B).
