LiftMaster K71-D1PH Guia De Inicio Rapido

APPLICATION
This wiring modifi cation is available for models T, J and H (for
1 Phase, 3 Phase and 575V Logic 5.0 operators).
This brake kit will either replace an existing brake or add a brake to an
operator that does not have a brake (1/3 or 1/2 HP). This design may
differ from a caliper style brake being replaced.
If a brake is being replaced, many of the kit components and wiring may
be reused from the existing operator (wiring harness, conduit, etc.).
INSTALLATION
1. Disconnect power to operator.
2. Remove the belt and motor pulley from the motor shaft.
3. If Brake Kit is being used to replace an existing brake, the original
brake assembly must be removed, including the square brake hub. A
small gear puller makes removal of the hub easier. Smooth any burrs
on the shaft with a fi le.
4. Refer to brake plate spacing guidelines on page 2 to assure belt/pulley
alignment. Spacing is important to ensure the brake drum can be
installed fl ush to the brake shoes.
5. Install brake assembly onto motor and hand tighten with the 4 nuts
provided.
6. Install brake drum on the motor shaft. Activate brake plunger if
necessary for easier install. Insert key stock and set screw to lock
brake drum in place. Once the brake drum is installed and centered,
tighten the 4 brake assembly nuts. Ensure the drum is not installed
too far into the assembly making contact with the assembly plate; this
will cause the drum to rub while it spins, creating noise and possible
premature wear/failure.
7. Install motor pulley on motor shaft. The clutch pulley and motor pulley
must be aligned in the same plane. If necessary, loosen the motor
mounting bolts to assist with alignment and re-tighten.
8. Install the belt and secure the set screws into the motor pulley.
