APPLICATION NOTES
• Not all part number combinations are available. Please contact your Sales Representative for available part numbers.
• 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.
• A back-up wrench must be used to hold the bottom nut stationary during installation.
