REPLACEMENT OUTLET/CONVERSION KIT
TO PLUG-IN TRANSFORMER
MODEL K76-36296-1
OVERVIEW
The Replacement Outlet/Conversion Kit is ONLY compatible with 120 Vac LA500 gate
operators with a standard control box. The Replacement Outlet/Conversion Kit can
replace the current accessory outlet and/or convert to a plug-in transformer system.
The kit comes with a replacement accessory outlet and a junction box cover. A
plug-in transformer (not provided, Model APOW3) is necessary for the conversion.
To reduce the risk of SEVERE INJURY or DEATH:
• ANY maintenance to the operator or in the area near the operator MUST NOT
be performed until disconnecting the electrical power (AC or solar and
battery) and locking-out the power via the operator power switch. Upon
completion of maintenance the area MUST be cleared and secured, at that
time the unit may be returned to service.
• Disconnect power at the fuse box BEFORE proceeding. Operator MUST be
properly grounded and connected in accordance with national and local
electrical codes. NOTE: The operator should be on a separate fused line of
adequate capacity.
• ALL electrical connections MUST be made by a qualified individual.
• DO NOT install ANY wiring or attempt to run the operator without consulting
the wiring diagram. We recommend that you install an edge sensor BEFORE
proceeding with the control station installation.
• ALL power wiring should be on a dedicated circuit and well protected. The
location of the power disconnect should be visible and clearly labeled.
• ALL power and control wiring MUST be run in separate conduit.
NOTE: The replacement accessory outlet may not be used.
REMOVE THE TOROID ASSEMBLY
1 Disconnect ALL POWER.
2
Open the control box cover and unplug the battery connector from the J15 plug
on the control board (Figure 1-A).
3
Cut the red and black wires going from the battery connector to the bridge
rectifier on the toroid assembly (Figure 1-B). Cap the wires with wire nuts since
they will no longer be used.
4
Remove the toroid assembly from the control box by loosening the four screws
and lifting the assembly up and out (Figure 1-C).
5
Disconnect the incoming power wires from the toroid assembly (Figure 1-D).
6
Disconnect the wires from the accessory outlet to the toroid assembly
(Figure 1-E).
7
Discard the toroid assembly.

INSTALL THE TRANSFORMER
The transformer can be installed inside the control box or it can be connected to an
external receptacle. Follow the instructions according to your application.
CONTROL BOX INSTALLATION
1
Run the AC power wires to the control box (if applicable).
2
Connect the green wire from the accessory outlet to the incoming earth ground
rod wire using a wire nut (Figure 2-A).
3
Connect the white wire from the accessory outlet to the incoming NEUTRAL
(white) power wire using a wire nut (Figure 2-A).
4
Connect the black wire from the accessory outlet to the incoming HOT (black)
power wire using a wire nut (Figure 2-A).
5
Install the junction box cover (Figure 2-B). Ensure the wires are not pinched.
6
Wire the transformer (not provided) to the CHARGER input on the control board
(positive to positive and negative to negative) (Figure 2-C).
7
Plug the transformer into one of the accessory outlets.
8
Plug the battery connector to the J15 plug labeled BATT(-)(+) DC(-)(+) on the
control board (Figure 2-D). The control board will power up. NOTE: You may
see a small spark when plugging the J15 plug into the board.
9
Turn ON AC power to the operator.

Longer wire runs are susceptible to surges and lightning strikes.
EXTERNAL RECEPTACLE INSTALLATION
1
Run low voltage wire between the control box and the external receptacle
(Figure 3-A). The transformer must be located in a dry location that is protected
from weather conditions, such as inside the house or garage.
2
Install the junction box cover (Figure 3-B). Ensure the wires are not pinched.
3
Wire the transformer (not provided) to the CHARGER input on the control board
(positive to positive and negative to negative) (Figure 3-C).
4
Plug the transformer into the external receptacle (Figure 3-D).
5
Plug the battery connector to the J15 plug labeled BATT(-)(+) DC(-)(+) on the
control board (Figure 2-E). The control board will power up. NOTE: You may
see a small spark when plugging the J15 plug into the board.
