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
DEH202 or Maintenance Manual 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. Assemble the trip paddle over the circuit breaker trip
shaft as shown in Figure 3. Secure the trip paddle to
the trip shaft using the # 10-32 screw and spring
washer provided. Install the # 8-32 adjusting screw and
nut as shown in Figure 3.
4. Assemble the Network Interlock mounting bracket to
the circuit breaker frame using two sets of 3/8-inch
countersunk bolts and washers as shown in Figure 4.
5. 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.
6. 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
(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 set lever and the trip 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.
8. Manually push the set lever toward paddle, locking the
Network Interlock into the SET position (shown in
Figure 6). Check to ensure that this operation causes
the trip paddle to move.
9. 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.
10. Fasten the manual reset assembly bracket to the
breaker frame using two sets of 1/4-inch hex-head
bolts and lock washers as shown in Figure 5.
11. Assemble the two reset rods as shown in Figure 5 and
Figure 6. Fasten the top end of the vertical rod to the
reset lever with two flat washers and one push nut as
shown Figure 6.
12. Pull the manual reset knob shown in Figure 5. Check
that the Network Interlock has returned to the RESET
state, as shown in Figure 7.
13. Charge and close the breaker. The breaker should
close properly since the Network Interlock is RESET.
14. 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.
15. Route the wires from the Network Interlock to the
secondary disconnect as shown in Figure 8 and secure
them with cable ties.
16. 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 numbering
scheme.
17. 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.
18. 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.
19. Charge the breaker manually or electrically. Close the
breaker. The breaker should trip open, discharging
the closing springs.
20. 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.
21. Charge and close the breaker. The breaker should
close properly.
22. Set the Network Interlock, and repeat Steps 17 through
21 five times.
