NOTICE

SecoVac Lift Truck – Operation Manual 4 of 12
The SecoVac Vacuum Circuit Breaker (VCB), Voltage
Transformer (VT) tray, Control Power Transformer (CPT) tray,
and Ground and Test (G&T) device should only be handled
with Lift Truck during installation and removal. The lift truck
allows the before mentioned parts to be elevated to the top or
bottom compartment in the SecoGear switchgear or SecoBloc
OEM Modules, Figure 1.
Floor Lock
For additional safety during the handling of the SecoVac VCB
or the other components, the lift truck is equipped with a floor
lock, Figure 2.
Compartment Interlock
The compartment interlock will lock the lift truck to the
SecoGear switchgear or SecoBloc OEM Module compartment
for a safe transfer to and from the equipment during
installation or removal, Figure 3.
Hand Winch
The hand winch is connected to a system of pulleys on both
sides of the lift truck to facilitate the lifting or lowering the
SecoVac VCB, VT & CPT trays, and G&T device. The system is
designed for a 700lbs lifting capacity, Figure 4.

1. General Description

SecoVac Lift Truck – Operation Manual 5 of 12
A. Place the VCB onto the Lift Truck
Maximum recommended lifting capacity for the lift truck
is 700 lbs.
NOTICE
1. Check the lifting and interlocking mechanisms of the lift
truck for smooth operation, and inspect the cables in the
hand winch system for any signs of damage, fatigue, or
wear before operation.
2. To pick up a VCB from the floor level, first lower the lifting
platform to the lowest position, Figure 5.
Before loading the SecoVac VCB onto the lift truck, assure that
it is in the open position and with the springs discharged by
checking the status of the indicators on the front cover.
Figure 5. Lowered Lifting Platform
4. Move the lift truck in front of the VCB and lock truck in
place using the floor lock shown in Figure 7. Now roll the
VCB onto the rails of the lift truck. The wheels on the VCB
should follow the rail guides.
Figure 7. Press the Front Pedal to Lock Lift Truck
Figure 9. SecoVac VCB Properly Mounted on Lift Truck
5. The VCB should be pushed onto the rails until the locking
tabs on the side lock into the slots on the hoist rails. Check
that the locking tabs on both sides are engaged and locked
into position on the lift truck rails, Figure 8. Once both tabs
are locked into the slots, the VCB is ready to be lifted to the
correct position for installation. Figure 9 shows properly
loaded VCB locked in position, and compartment interlock
in the retracted position.

2. Installing the SecoVac VCB
3. Adjust the rails on the hoist before loading the VCB. The
rails are adjustable and have 3 sets of slots on each side
of the hoist platform. These rails must be latched into the
center most slots of the platform for proper operation to
pick up the VCB, Figure 6.

1. Check the lifting and interlocking mechanisms of the lift
truck for smooth operation, and inspect the cables in the
hand winch system for any signs of damage, fatigue, or wear
before proceeding.
2. Open the SecoGear compartment door, and position the lift
truck in front of the switchgear compartment.
3. Turn the hand winch clockwise to raise, or counterclockwise
to lower, the VCB into position, Figure 11. Adjust the height
of the VCB to align with the guide slots located in the
switchgear compartment, Figure 14.
6. Release the floor lock by depressing the lever on the right or
left-hand side of the floor lock and move the lift truck away,
Figure 10.

8. Lock the VCB in the DISCONNECTED/TEST position
using the spring-loaded locking handles, Figure 21.
The tabs on the VCB will engage slots in the switchgear
compartment rails
6. Engage the compartment interlock onto the switchgear
compartment. This operation requires a combination of
steps shown on Figures 17 through Figure 19.
a. Push the operation handle until it is fully engaged in the
switchgear compartment slot.

b. Lock the operation handle into place by pressing
down and rotating the interlock pin clockwise until it
is fully engaged.

the Latch Handle
7. To insert the VCB into the switchgear compartment,
push the two locking handles on the front of the VCB
inward (toward the center) to release from the lift truck
and push the VCB onto the rails and into the switchgear
compartment, Figure 20.

Verify that the VCB safety stop in the switchgear
compartment has returned to the normal
extended position.
CAUTION
10. Verify that the VCB safety stop has returned to the
extended position, Figure 24. If necessary, release by
inserting a screw driver into the slot to dislodge, Figure 25.
Figure 22. Rotate Interlock Pin Counterclockwise to Unlock the Latch Handle
9. Once the VCB is in the switchgear compartment,
disengage the lift truck compartment interlock by rotating
the interlock pin counterclockwise, Figure 22, then move
the handle to the left and pull the latch handle toward
you and from the switchgear compartment until it is
fully retracted, Figure 23.

engage in the switchgear rail guide slots and the rail stops
engage the switchgear. Lock the lift truck in position by
pressing down on the truck locking pedal, Figure 16.
6. Engage the lift truck compartment interlock to secure
the truck to the switchgear compartment.
7. Push the two locking handles on the front of the
VCB inward to unlock the VCB from the switchgear
compartment, Figure 20.
8. Pull the VCB forward onto the lift truck rails and lock
in position on the lift truck using the locking tabs on
both sides of the VCB. Ensure they engage and lock into
position, Figure 8.

the lift truck away from the switchgear.
11. Lower the VCB to the ground.
3. Removing the SecoVac VCB

SecoVac Lift Truck – Operation Manual 10 of 12
Do not over torque the racking handle, applied force
should not exceed 22.12 ft lb (30 N/m)
CAUTION
When it makes a clicking sound, the VCB is now in the
Connected position. The VCB position indicator will change
the status from “TEST” to “CONNECTED”, Figure 32 through
Figure 34.
1. Connect the secondary plug of the VCB into the socket
at the top of the switchgear compartment and lock it,
Figure 27 and Figure 28.
When racking the VCB from CONNECT to DISCONNECT,
or DISCONNECT to CONNECT, do not stop or pause at
any intermediate position. Failure to engage in either
CONNECT or DISCONNECT position will render the
VCB inoperable.
CAUTION

it cannot be rotated any further.
4. Racking the SecoVac VCB to Connected Position

SecoVac Lift Truck – Operation Manual 11 of 12
When racking the VCB from CONNECT to DISCONNECT,
or DISCONNECT to CONNECT, do not stop or pause at
any intermediate position. Failure to engage in either
CONNECT or DISCONNECT position will render the
VCB inoperable.
1. With the VCB in the CONNECTED position and open,
close the door and insert the racking handle, Figure 29,
into the racking access hole located at the bottom of
the door, Figure 30, until the racking socket is engaged
with the racking drive screw.
