QUESTION: WITH THIS SURGE PROTECTOR MOD.# 990LM CAN I JUST PLUG THE POWER CORD INTO IT THE SIMPLE WAY. OUR DO IHAVE TO HARD WIRE IT LIKE OTHER CUSTOMERS HAVE DONE. WHAT IS THE DIFFERENCE? by RONALD B 11/15/2014

ANSWER: Well, the power cord does plug into it directly. But if the S.P. isn't "fed" power from house's power supply, the electric motor and the door's closing safety sensors cannot function. The S.P. is the intermediate safety device between the garage's ceiling mounted electric wires and the little wires that connect into the door's safety sensors located on the lower two sides of the garage entry threshold. by Richard B a

ANSWER: This 990LM works like any other one-outlet surge protector. Just plug it into the wall or ceiling outlet and then plug the opener into it. Since surges can come from other connected wires, you also get protection for the wires from the door sensor detectors. Just follow the instructions -- it's a DIY install. by Jack G a
QUESTION: how is it installed? by Mike L 10/1/2013
ANSWER: I had the opener plugged into the surge protector but still lost the circuit board yesterday from another lightning strike. I did not have the additional wiring plugged in. Am going to wire the additional wiring now. Not sure if I still would have lost the circuit board again if the additional wiring was plugged into surge protector. Frustrating that I have to buy another board when I did the preventative surge protection. by David D a
ANSWER: I simply plugged the surge protector in to the electric outlet in the ceiling above the garage door opener and then I plugged the garage door opener into the surge protector. There are instructions that come with the surge protector that provide for alternate wiring. by Kevin E a

ANSWER: We ran the wires that normally feed into back of opener into the surge protector 4 inputs on side of protector. We then ran additional wire from surge protector tied into original wires in the 4 inputs back to the opener. You need extra wire to do this. Then plug opener into surge protector then plug it in to outlet. by Stephanie B a
