Module Replacement Instructions

Removing the Network Interlock Module

Use the following procedure, illustrated in Figure 5 and
Figure 6 to remove the Network Interlock module.


1. Disconnect the six wires from the Network Interlock

module. Label each wire as it is removed. Cut wire ties

as necessary.

2. Remove the push nut and washer from the top of the

manual reset rod and slide the rod out of the reset lever

as shown in Figure 6.

3. Remove the Network Interlock module from the

mounting plate by removing the three nuts and

washers, as shown in Figure 5.

Installing the Network Interlock Module

Use the following procedure to install the Network
Interlock module as a replacement, as illustrated in
Figure 5 and Figure 6.


1. Open the circuit breaker and remove it from the

cubicle or substructure. Check to ensure the breaker

closing springs are DISCHARGED. (See DEH202 or

DEH204 for detailed instructions.)

2. Carefully place the circuit breaker on a suitable

working surface, resting on the primary disconnects, so

that the bottom of the circuit breaker is accessible.

3. Fasten the Network Interlock module to the mounting

bracket using three sets of # 8-32 nuts, spring washers,

and flat washers as shown in Figure 5.

4. Ensure the Network Interlock is in the RESET state

(shown in Figure 7) by manually rotating the reset lever

counterclockwise. If the Network Interlock was SET,

this operation will cause the set lever to retract away

from the trip paddle.

5. With the breaker open, charge the breaker closing

springs. Do not close the breaker. Adjust the gap

between the Network Interlock set lever and paddle by

rotating the adjusting screw as shown in Figure 7. The

distance between the set lever and the trip paddle must

be between 0.06 and 0.09 inch.

6. Manually push the set lever toward paddle, locking the

Network Interlock into the SET position. Check to

ensure that this operation causes the trip paddle to

move.

7. Close the breaker by either depressing the close button

or activating the close coil circuit. The breaker should

not have closed since the Network Interlock was SET.

8. Fasten the top end of the vertical manual reset rod to

the reset lever with the push nut shown in Figure 6.

9. Pull the manual reset knob. Check that the Network

Interlock has returned to the RESET state, as shown in

Figure 7.

10. Charge and close the breaker. The breaker should

close properly since the Network Interlock is RESET.

11. Open the breaker. Connect six wires to the available

terminals on the Network Interlock device. Connect

two of the wires to the NC and COM terminals of the

microswitch as shown in Figure 9.

12. Reset the Network Interlock by pulling the manual

reset knob. The Network Interlock status circuit should

be open. Close the breaker manually or electrically.

The breaker should close properly.

13. Set the Network Interlock by applying 120 VAC across

terminals 15 and 21 on the secondary disconnect. The

breaker should trip open and the status circuit should

change from open to close.

14. Charge the breaker manually or electrically. Close the

breaker. The breaker should trip open, discharging

the closing springs.

15. Reset the Network Interlock by applying 120 VAC

across terminals 20 and 21 on the secondary

disconnect. The status circuit should change from

closed to open.

16. Charge and close the breaker. The breaker should

close properly.

17. Set the Network Interlock, and repeat Steps 12

through 16.
