Kit Installation Instructions
Use the following installation procedure for breakers
that were not equipped with a Network Interlock
accessory at the factory.
1. Open the circuit breaker and remove it from the
cubicle or substructure. Check to ensure the breaker
closing springs are DISCHARGED. (See User’s Guide
DEH201 or Maintenance Manual 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. Locate the close coil on the underside of the breaker.
Check for silicone insulation (RTV) on the two right-
most screw terminals. If there is no insulation, bend the
four wires and their terminals toward the close coil
body. Cover all exposed metal of the terminals with
silicone insulation (RTV).
4. 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
5. Assemble the trip paddle and paddle clamp over the
circuit breaker trip shaft as shown in Figure 4. Secure
the paddle clamp to the shaft using the #10-32 screw
and spring washer provided.
6. Fasten the Shunt Trip accessory to the mounting plate
beside the Network Interlock. See DEH203 or DEH168
for detailed instructions.
7. Assemble the accessory mounting plate to the circuit
breaker bottom frame using four sets of #10-32 screws,
spring washers, and flat washers as shown in Figure 5.
8. 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.
9. 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 assembly must be between 0.06 and 0.09
inch.
10. Manually push the set lever toward the trip paddle,
locking the Network Interlock into the SET position.
Check to ensure that this operation causes the trip
paddle to move.
11. 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.
12. Assemble the manual reset using two sets of ¼ inch hex-
head bolts, spring washers, and flat washers as shown in
Figure 7.
13. Push the manual reset button. Check that the
Network Interlock has returned to the RESET state, as
shown in Figure 6.
14. Charge and close the breaker. The breaker should
close properly since the Network Interlock is RESET.
15. Open the breaker. Connect six wires to the available
terminals on the Network Interlock device using the
crimp-on terminals provided. Connect two of the wires
to the NC and COM terminals of the microswitch as
shown in Figure 9.
16. Route the wires from the Network Interlock to the
secondary disconnect as shown in Figure 8 and secure
them with cable ties.
17. Using the spade terminals provided, connect a wire
from the trip and reset solenoids to terminals 15 and 20
of the secondary disconnect, respectively. Connect the
other two solenoid wires to terminal 21. Connect the
two microswitch wires to terminals 16 and 19. Figure 10
shows the secondary disconnect terminal numbering.
18. Reset the Network Interlock by pushing the manual
reset lever. The Network Interlock status circuit should
be open. Close the breaker manually or electrically.
The breaker should close properly.
19. 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 closed.
20. Charge the breaker manually or electrically. Close the
breaker. The breaker should trip open, discharging the
closing springs.
21. 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.
22. Charge and close the breaker. The breaker should close
properly.
23. Set the Network Interlock, and repeat Steps 18 through
22.
