Earth Ground Rod
Check national and local
codes for proper depth
High and Low Voltage UL approved conduit. Power and
control wiring MUST be run in separate conduits
Warning Placard on both sides of gate.
Gate MUST be level. Gate and gate post MUST be plumb.
DO NOT weld the crossbar on just a few pickets, or
they could bend.
There should only be a
maximum of 4" (10.2 cm)
from the center of the hinge
to the edge of the post or
column. If the distance is
greater than 4" (10.2 cm)
entrapment protection for this
area is required.
Gate MUST have a
smooth bottom edge, no
protrusions should exist.
Remove ANY/ALL wheels
from the bottom of gate.
Gate MUST NOT
hit or drag across
ground.
Gate MUST swing freely and be
supported entirely by its hinges.
DO NOT install next to sprinklers or any area that
may expose the bottom of operator to water.
DO NOT install on uphill or downhill gates.
DO NOT install on ANY pedestrian passageways,
doorways, or gates.

Wired connection in a dual gate setup is optional. Operators
can be setup for wireless dual gate communication if a second
control box is purchased.
This operator contains an inherent (internal) entrapment protection system and REQUIRES
the addition of a LiftMaster external monitored entrapment protection system (non-contact
photoelectric sensor or contact edge sensor) for EACH entrapment zone prior to gate movement.
An entrapment zone is every location or point of contact where a person can become entrapped
between a moving gate and a stationary object. Your application may contain one or many
entrapment zones. System includes three monitored entrapment protection inputs capable of
covering all entrapment zones (and a total of six inputs with the optional expansion board). Use
only LiftMaster approved entrapment protection devices.

For a gate operator utilizing a contact sensor, if the bottom
edge of a swing gate is greater than 6 inches (15.2 cm) above
the ground at any point in its arc of travel, one or more contact
sensors shall be located on the bottom edge.
If utilizing a contact sensor as entrapment protection, one
or more contact sensors shall be located on the inside and
outside leading edge of a swing gate.

If the distance between the open gate and the wall is less than 16"
(40.6 cm) entrapment protection for this area is required. Entrapment
protection is required for the area between the gate and the curb.
