• A back-up wrench MUST be used to hold the bottom nut stationary during installation.
• Solenoids applied in battery charging circuits should be protected from higher than rated voltage during charging. The
service life may be affected by this condition and the solenoid may or may not operate the circuit as intended.
• Circuits should be designed to provide safe operation should the solenoid fail in either the open or closed position.
• Special construction options, including a curved bracket, may be available under other part numbers, including111-
xxxD (short can), 111-xxxE (long can), 5608-x and 878x-x.
