Control - Chamberlain Merlin MJ3800R Installation And Operating Instructions Manual

INSTALLATION STEP 3
ATTACH THE EMERGENCY RELEASE ROPE
AND HANDLE
• Thread one end of the rope through the hole in the top
of the red handle so "NOTICE" reads right side up as
shown. Secure with an overhand knot at least 25mm
(1") from the end of the rope to prevent slipping.
• Thread the other end of the rope through the loop in the
emergency release cable.
• Adjust rope length so the handle is no higher than 1.8m
(6') above the floor. Secure with an overhand knot.
NOTE: If it is necessary to cut the rope, heat seal the
cut end to prevent unraveling.
INSTALLATION STEP 4
ELECTRICAL REQUIREMENTS
To avoid installation difficulties, do not run the opener
at this time.
To reduce the risk of electric shock, your door opener has
a grounding type plug with a third grounding pin. This plug
will only fit into a grounding type outlet. If the plug doesn't
fit into the outlet you have, contact a qualified electrician to
install the proper outlet.

INSTALLATION STEP 5
INSTALLING THE MULTI-FUNCTION WALL

CONTROL

Note: any connection to your MJ3800R should be
voltage free and Normally open.
There are 2 screw terminals on the back of the multi-function
door control. Strip about 6mm of insulation from bell wire.
Separate wires enough to connect the white/red wire to R
terminal screw 1 and the white wire to W terminal screw 2.
Fasten the multi-function door control to an inside garage
wall with sheet metal screws provided. Drill 4mm holes and
use anchors if installing into plasterboard wall. A convenient
place is beside the service door and out of reach of children.
Run the bell wire up the wall and across the ceiling to the
garage door opener. Use insulated staples to secure wire.
The receiver quick connect terminals are located on the
control board. Connect the bell wire to the terminals as
follows: white/red to red and white to white.

To prevent possible SERIOUS INJURY or DEATH from
electrocution or fire:
• Be sure power is not connected to the opener, and
disconnect power to circuit BEFORE removing cover.
• Door installation and wiring MUST be in
compliance with ALL electrical and building
codes.
• NEVER use an extension cord, 2-wire adaptor or
change plug in any way to make it fit outlet. Be sure
the opener is grounded.
• If the supply cord is damaged, it must be replaced by
the manufacturer or it's service agent or similarly
qualified person in order to avoid hazard.
To prevent possible SERIOUS INJURY or DEATH from
a falling door:
• If possible, use emergency release handle to
disengage door ONLY when door is CLOSED. Weak
or broken springs or unbalanced door could result in
an open door falling rapidly and/or unexpectedly.
• NEVER use emergency release handle unless the
doorway is clear of persons and obstructions.
