WARNING: To prevent electrostatic discharge (ESD) damage when handling electronic equipment, always wear an
antistatic wrist strap attached to an unpainted, grounded metal object. Ensure the wrist strap has maximum contact
with bare skin. If wires are to be buried or covered, conduit must be used to protect the wires.

IMPORTANT: After installing the AC solid state relay, you may see a decrease in rectifier output due to a slight voltage (up to 1.7V)
drop across the relay. The decrease will be based on the current across the relay.
NOTE: These procedures are general steps for a typical installation. If your installation requires additional technical assistance, please
call the Technical Services group at 1-800-229-3404.
