5. Insert the ground and test device into the
correct compartment. The ground and test
device is rolled into the compartment, in
the same manner as the circuit breaker it
temporarily replaces, until the ground and
test device encounters a positive “stop”.
6. Transfer key KC to key lock K3 and rotate
the key (Figure 3, m) . The KC key is now
captive. The ground and test device
racking shaft is now accessible.
7. Insert the racking handle and rotate the
handle clockwise to move the ground and
test device into the “Connected” position.
The racking handle is also equipped with an
input torque limiter that will indicate limit
to the operator by a mechanical ratcheting
mechanism for positive operator feedback.
Remove the racking handle.
8. Rotate key KC to lock the ground and test
device in the connected position. The KC
key is now released.
9. Transfer key KC to key lock K2
(Figure 3, k) and rotate key KC. The key KC is
now captive and the KB key is released
(Figure 3, i) .
10. Transfer key KB to key lock K1 (Figure 3, r) .
Rotate key KB. The ground and test device
control circuit is now enabled. The KB key
is now captive and the KCF key is released
(Figure 3, q) .
11. Verify that the control selector switch on
the front of the ground and test device is in
the “OFF” (center) position (Figure 3, c) .
12. Connect the power cord of the remote
control box to the ground and test device
(Figure 3, n) . Ensure the cord is locked into
the connected position by turning the plug
clockwise.
13. Connect the secondary disconnect plug
to the receptacle on the ground and test
device (Figure 3, d) .
14. Move to control selector switch from “OFF”
position to “CLOSE” position (Figure 3, c) .
15. Turn the remote control box "ON"
(Figure 1, a) and depress the "CLOSE"
pushbutton (Figure 1, b) to close the ground
and test device.
16. Move the control selector switch from the
“CLOSE” position to the “OFF” position
(Figure 3, c) .
17. Turn the remote control box "OFF" and
disconnect the power cord of the remote
control box from the ground and test
device (Figure 3, n) .
18. Rotate key KCF in key lock K1 to electrically
lock the ground and test device in the
“CLOSED” position. Remove key KB from
key lock K1 (Figure 3, r) .
19. Secure key KB in lock box on premises.

The CON ED and CUSTOMER ground and test
devices are supplied with similar interlock
functions. However, the CON ED device uses
Key KU for Key Lock K1 and the CUSTOMER
device uses Key KCF for Key Lock K1. Key KU
and Key KCF are NOT INTERCHANGEABLE.
Although these operating procedures contain
illustrations of the CUSTOMER device, these
procedures also apply to the CON ED device.
For procedures that refer to Key KCF for the
CUSTOMER device, the same procedures apply
to Key KU for the CON ED device.
NOTICE
1. Obtain the KB key through proper control
procedures.
2. Transfer key KB to key lock K1 (Figure 3, r)
and rotate key. Key KB is now captive and
key KCF is released (Figure 3, q) . The control
circuit for the ground and test device is now
enabled.
3. Verify that the control selector switch on
the front of the ground and test device is in
the “OFF” (center) position (Figure 3, c) .
