ATTACHING THE CHAIN BRACKETS and
PLACING THE LPX1700 OPERATOR
The chain brackets provided with the LPX1700 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 Figs. 9 & 10.
Do not over-tension the chain.
ELECTRICAL POWER CONNECTIONS
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 High
Voltage AC Line Connection box under the operator’s control box.
Review Figures 5 and 7, pages 6 and 7. 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 High Voltage AC Line
Connection box face plate. Using the wire nuts provided, attach the
electrical service lead wires to the electrical hook-up wires in the
connection box per the wiring diagram on page 23.
NOTE: The LPX1700 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.
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 LPX1700. 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
shunted to ground. This must be done without raising the potential of
the circuitry in the LPX1700, with respect to ground, to the levels that
will damage the solid state circuitry. Lightning strikes generate
enormous currents for very short periods of time. Unfortunately, the
period of time is long enough to damage solid state components and
many times, other components. The key to success is a very low
resistance path from the surge protector to ground for these currents in
addition to a surge protector that will act fast enough to protect the solid
state circuitry. Several manufacturers offer suitable surge protectors.
RISK OF ELECTROCUTION
Do not begin the electrical connection procedures until the
power is turned off at the circuit breaker.

TO REDUCE THE RISK OF DAMAGE DUE TO LIGHTNING,
ENSURE A SOLID GROUND FROM THE LPX1700 GROUND
WIRE IN THE SERVICE ENTRANCE 4 x 4 HANDY BOX TO
THE ELECTRICAL SERVICE GROUND OR TO A EARTH
GROUND STAKE NEAR THE LPX1700.
