ATTACHING THE CHAIN BRACKETS and
PLACING THE LPX1000 OPERATOR
The chain brackets provided with the LPX1000 operator are mounted
on each end the gate with the centerline of the slot 8" above the top of
the operator pad. You will normally require a welder, or an electric
drill with a 3/8" bit, for attaching the chain brackets to the gate. See
Figures 9 and 10.
From the center of the slot in the bracket, run a string line taught from
one chain mounting bracket to the other. Place the operator on the new
pad or existing concrete base and position the unit so that the string is
centered on the primary drive sprocket, centered on the pad from left to
right, and parallel with the gate frame as shown in Figure 10a. Using
the operator as a template, mark and drill the appropriate holes for the
required anchor bolts (four [4] ½” anchor bolts are required). Install the
anchor bolts per the bolt manufacturers instructions.
Re-sit the operator over the anchor
bolts, making sure the operator is
sitting level. If any corners
of the operator are
resting above the
pad, place
flat
washers as shims between the operator and concrete pad (around the
anchor bolts). Place the flat washers, lock washers and nuts on the
anchor bolts and tighten down the operator securely.
Attach one end of the chain to the gate and thread the other end through
the idler pulleys and drive sprocket. Attach the free end to the bracket
on the opposite end of the gate and tension the chain. See Figures 9 and
10.
Do not over-tension the chain.
ELECTRICAL HOOKUP
The operator requires a 3-wire, 115 VAC electrical hook-up for proper
operation. Ideally, the conduit containing the hook-up wires should exit
the concrete pad under the operator. There is a 3" gap in the front of
the bottom plate of the operator provided for this purpose. Run flexible
conduit from the point where the conduit exits the pad and attach it to
the bottom of the right junction box at the front of the frame. Review
Figure 5, Page 6. If the hook-up exits the pad external to the operator,
there's a 7/8" diameter hole in each side of the frame near the front of
the operator. Connect the conduit to either hole and cut a small slot in
the 1-1/2" high skirt around the base of the cover. This will allow the
cover to fit down flush with the conduit in place. Review Figure 7,
Page 7. Remove the right junction box face plate. Using the wire nuts
provided, attach the three lead wires to the electrical hook-up wires in
the following manner:
1. The BLACK wire attaches to the 115 VAC HOT wire.
2. The WHITE wire to the 115 VAC NEUTRAL wire.
3. The GREEN wire to the GROUND wire.
NOTE: The LPX1000 control board comes equipped with a built-in
surge protection which MAY prevent damage to the controller board in
the event of a nearby lightning strike or a surge in the power lines. For
the surge protector to function, and as a general precaution, the operator
must be properly grounded. The third wire for the ground must be
installed .
ADDITIONAL LIGHTNING PROTECTION
For those areas where a high probability of ground lightning strikes
exists (Florida, Georgia, etc.), additional lightning protection should be
installed in the LPX1000. Although it may not be possible to protect
against all strikes, additional protection will substantially reduce the
occurrence of lightning damage. Industry lightning data indicates that
the most strikes enter an appliance through the power lines. Effective
protection requires that the surge current from the lightning strike be
RISK OF ELECTROCUTION
Do not begin the electrical connection procedures until the
power is turned off at the circuit breaker.
