990LM Garage Surge Protector
Owner’s Instructions:
The Garage Door Opener Surge Protector is designed to protect LiftMaster®
garage door openers against damage from lightning and power surges. The Surge
Protector will stop radiated surge currents from coming through wall control
and safety sensors, as well as surge currents from coming through AC power
line according to the rating chart shown below.
Plug the Surge Protector into grounded (3-wire) 120V AC outlet within four (4)
feet of the garage door opener. Plugging Surge Protector into a GFCI (Ground
Fault Circuit Interrupter) is acceptable, but not recommended as power surges
may cause the GFCI to trip and you will need to reset the outlet in order to
operate the garage door opener.
WARNING
To prevent possible SERIOUS INJURY or DEATH from electrocution:
- Unplug garage door opener from AC outlet and be sure power is disconnected BEFORE installing the Surge Protector.
- Connect terminals ONLY to 24 VOLT low voltage wires.
- The Surge Protector is ONLY for indoor Use.
- DO NOT perform installation during a lightning storm (visible lightning)
Installing the wall control wires:
- At the garage door opener, remove the white-white/red wires (for wall control) from Quick-Connect terminals.
- Using a 5′ piece of white-white/red 22 AWG bell wire (not included), strip 7/16″ of insulation from both ends.
- With existing wall control wire and new wire, use pliers to twist same colored wires together.
- Referring to wiring diagram, insert wall control wires into red and white connectors on Surge Protector.
- Insert opposite ends of new wire into Quick-Connect terminals located on garage door opener as follows: white to white and white/red to red.
Installing the safety sensor wires:
- At the garage door opener, remove the white-white/black wires (for safety sensors) from Quick-Connect terminals.
- Using a 5′ piece of white-white/black 22 AWG bell wire (not included), strip 7/16″ of insulation from both ends.
- With existing safety sensor wires and new wire, use pliers to twist same colored wires together.
- Referring to wiring diagram, insert safety sensor wires into white and gray connectors on Surge Protector.
- Insert opposite ends of new wire into Quick-Connect terminals located on garage door opener as follows: white to white and white/black to gray.
Installing the Surge Protector:
- Plug Surge Protector into AC outlet
- Plug garage door opener into outlet on front of Surge Protector
- Test garage door opener for proper operation. Be sure to test all functions including wall control, keypad, safety sensors (Door Reversal Test – See garage door opener manual for instructions) and any other accessories.
LED Indicator: The indicator light should be illuminated when the surge protector is plugged into AC power and is protecting your garage door opener system. If the indicator light goes out, the surge protector has sacrificed (depleted) itself to protect the garage door opener system and should be replaced immediately.

Chamberlain Connected Equipment Limited Warranty
Chamberlain warrants to the original purchaser of any Chamberlain Surge
Protector that the surge protector shall be free of defects in material and
workmanship for a period of five (5) years from the date of original purchase,
and will repair or replace, at its option, any defective surge protector free
of charge. The proper operation of the Chamberlain Surge Protector may destroy
the protector itself. Such an event is not a defect and is not covered by this
limited warranty.
For a period of five (5) years from the date of original purchase of any
Chamberlain Surge Protector, Chamberlain will repair or replace, at its
option, any LiftMaster garage door opener (“Connected Equipment”) which is
damaged by a transient voltage surge (an “Occurrence”), while properly
connected through a Chamberlain Surge Protector to a properly wired AC power
line with protective ground. This limited warranty is null and void unless all
wires leading into the equipment pass through an appropriate Chamberlain Surge
Protector as further described herein. Chamberlain reserves the right to
review the damaged Chamberlain Surge Protector, the damaged Connected
Equipment and the site where the damaged occurred. All costs of shipping the
Chamberlain Surge Protector and the damaged equipment to Chamberlain for
inspection shall be borne solely by the purchaser. Damaged equipment must
remain available for inspection until the claim is finalized.
All above warranties are null and void if the Chamberlain Surge Protector in
use during the occurrence is not provided to Chamberlain for inspection upon
Chamberlain’s request at the sole expense of the purchaser, Chamberlain
determines that the Chamberlain Surge Protector has been improperly installed,
altered in any way or tampered with, Chamberlain determines that the damage
did not result from the occurrence or that no occurrence in fact took place,
or Chamberlain determines that the Connected Equipment was not used under
normal operating conditions or in accordance with all labels and instructions.
All Chamberlain Surge Protectors must be plugged directly into the power
source and must not be “daisychained” together in serial fashion with other
power strips, UPS, other surge protectors or extension cords. Any such
installation voids the limited warranty. This limited warranty only protects
against damage to properly connected equipment where Chamberlain has
determined, in its sole discretion, that the damage resulted from an
Occurrence, and does not protect against acts of God such as flood,
earthquake, direct lightning strike, war, vandalism, theft, normaluse wear and
tear, erosion, depletion, obsolescence, abuse, damage due to low voltage
disturbances (i. e. brownouts or sags), nonauthorized program or system
equipment modification or alteration. This warranty is secondary to any
existing coverage of any Connected Equipment, including, but not limited to,
any manufacturer’s warranty, extended warranties or insurance coverage.
THIS LIMITED WARRANTY IS IN LIEU OF ANY OTHER WARRANTIES, EXPRESS OR IMPLIED,
INCLUDING ANY IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR
PURPOSE, OR OTHERWISE, AND OF ANY OTHER OBLIGATIONS OR LIABILITY ON SELLER’S
PART. THIS LIMITED WARRANTY DOES NOT COVER NON-DEFECT DAMAGE, DAMAGE CAUSED BY
IMPROPER INSTALLATION, OPERATION OR CARE (INCLUDING, BUT NOT LIMITED TO ABUSE,
MISUSE, FAILURE TO PROVIDE REASONABLE AND NECESSARY MAINTENANCE, UNAUTHORIZED
REPAIRS OR ANY ALTERATIONS TO THIS PRODUCT), REPLACEMENT OF BATTERIES AND
LIGHT BULBS OR UNITS INSTALLED FOR NON-RESIDENTIAL USE.
UNDER NO CIRCUMSTANCES SHALL SELLER BE LIABLE FOR CONSEQUENTIAL, INCIDENTAL OR
SPECIAL DAMAGES ARISING IN CONNECTION WITH USE, OR INABILITY TO USE, THIS
PRODUCT. IN NO EVENT SHALL SELLER’S LIABILITY FOR BREACH OF WARRANTY, BREACH
OF CONTRACT, NEGLIGENCE OR STRICT LIABILITY EXCEED THE COST OF THE PRODUCT
COVERED HEREBY. NO PERSON IS AUTHORIZED TO ASSUME FOR US ANY OTHER LIABILITY
IN CONNECTION WITH THE SALE OF THIS PRODUCT.
