WARNING
Electrical Shock Hazard
De-energize the bypass and wait 5 minutes minimum until the Charge LED turns off. Remove the
front cover and terminal cover to do work on wiring, circuit boards, and other parts. Use terminals
for their correct function only.
Incorrect wiring, incorrect ground connections, and incorrect repair of protective covers can cause death or serious
injury.
Only let approved personnel install, wire, maintain, examine, replace parts, and repair the bypass.
If personnel are not approved, it can cause serious injury or death.
Do not wear loose clothing or jewelry when you do work on the bypass. Tighten loose clothing and
remove all metal objects, for example watches or rings.
Loose clothing can catch on the bypass and jewelry can conduct electricity and cause serious injury or death.

Handle keypad batteries properly. Do not charge the battery or disassemble the keypad.
If the battery explodes, it can cause a fire.
Do not disassemble batteries. Do not expose batteries to heat or fire.
If the battery explodes, it can cause a fire.
Crush Hazard
Wear eye protection when you do work on the bypass.
If you do not use correct safety equipment, it can cause serious injury or death.
Only approved personnel can operate a crane or hoist to move the bypass.
If unapproved personnel operate a crane or hoist, it can cause serious injury or death from falling equipment.
Use a crane or hoist to move large bypasses when necessary.
If you try to move a large bypass without a crane or hoist, it can cause serious injury or death.
CAUTION
Crush Hazard
Tighten terminal cover screws and hold the case safely when you move the bypass.
If the bypass or covers fall, it can cause moderate injury.
NOTICE
Damage to Equipment
The keypad battery stays in use after you de-energize the bypass. When you will keep the bypass

of the battery is complete, replace the battery immediately.
A dead battery in the keypad can leak and cause damage to the keypad and bypass.
