Module Replacement
Removing the Network Interlock Module
Use the following procedure, illustrated in Figure 7, 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 manual reset assembly by removing the two
hex-head screws as shown in Figure 7.
3. Remove the accessory mounting plate as shown in
Figure 5.
4. Remove the Network Interlock module from the
mounting plate by removing the three sets of nuts and
washers, as shown in Figure 3.
Installing the Network Interlock Module
Use the following procedure to install the Network
Interlock module as a replacement, as illustrated in
Figure 5.
1. Open the circuit breaker and remove it from the cubicle
or substructure. Check to ensure the breaker closing
springs are DISCHARGED. (See DEH201 or DEH203 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 accessory
mounting plate using three sets of # 8-32 nuts, spring
washers, and flat washers as shown in Figure 3
4. Fasten the Shunt Trip accessory to the mounting plate
beside the Network Interlock. See DEH203 or DEH168
for detailed instructions.
5. Assemble the accessory mounting plate to the circuit
breaker frame using four sets of # 10-32 screws, spring
washers, and flat washers as shown in Figure 5.
6. Ensure the Network Interlock is in the RESET state
(shown in Figure 6) by manually rotating the reset lever
counterclockwise. If the Network Interlock was SET, this
operation will cause the set lever to retract
(counterclockwise) away from the trip paddle.
7. With the breaker open, charge the breaker closing
springs. Do not close the breaker. Adjust the gap
between the Network Interlock set lever and trip paddle
by rotating the socket-head adjusting screw as shown in
Figure 6. The distance between the set lever and the
trip paddle must be between 0.06 and 0.09 inch.
8. Connect the six wires to their corresponding
terminals on the Network Interlock device.
9. Reset the Network Interlock by pushing the manual
reset button. The Network Interlock status circuit
should be open. Close the breaker manually or
electrically. The breaker should close properly.
10. 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.
11. Charge the breaker manually or electrically. Close
the breaker. The breaker should trip open,
discharging the closing springs.
12. 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.
13. Charge and close the breaker. The breaker should
close properly.
14. Set the Network Interlock, and repeat Steps 9
through 13.
