LRA Linear Residential Actuator Installation Guide - 5 - 228158 Revision X13 2-3-2009
Operator Setup
Operator Mounting
The operator mounts on the post bracket pin and into the
gate bracket bushing. Refer to Figure 5.
With the gate closed, carefully position the operator over the mounting 1.
brackets.
Lower the operator onto the post bracket pin while guiding the 2.
operator’s worm drive traveler shaft into the gate bracket bushing.
Install the washer and clip-ring on the post bracket pin.3.
Install the washer and clip-ring on the traveler shaft.4.
Controller Connection
The Controller is mounted in a locked enclosure. Open the
cover for installation access. The operator’s interface cable
plugs into the Controller and connects to the operator’s
5-position terminal block.
Remove the operator’s wiring access plate (see Figure 6).1.
Connect the interface cable to Terminals 1-5 on the Controller (see 2.
wire colors and terminal numbers in Figure 6).
Route the interface cable through a wiring knockout in the control 3.
box and towards the operator. Be sure to leave enough slack in the
interface cable to allow for the gate swing.
Slide the O-ring over the end of the interface cable.4.
Connect the interface cable to the operator’s terminal block matching 5.
the same colors and terminal numbers used in Step 2 (see Figure 6).
Replace the operator’s wiring access plate being careful to align the 6.
O-ring below the cable clamp. The O-ring helps keep out moisture.
AC Power Connection
The control box contains a power disconnect switch to turn
on and off the power available to the operator. Following
wiring specifications on Page 2, incoming power should be
brought into the control box and connected to the labeled
pigtails from the disconnect box. A wiring connections print
can be found on the label inside the cover of the operator.
See Figure 7 for power option examples.
Earth Ground
Install a ground rod and connect it to the control box in every
installation. A good earth ground is necessary to allow the
Controller’s built-in surge and lightning protection circuitry
to work effectively.
✓ NOTE: Do not splice the ground wire. Use a single piece of solid
copper 12 AWG wire between the ground rod and the control box.
Install an 8-foot long copper ground rod within three feet of the control 1.
box.
Use a clamp to connect a solid copper 12 AWG ground wire to the 2.
ground rod.
Route the ground wire to the control box through a wiring knockout.3.
Connect the ground wire to the control box.4.
