INSTALLATION INSTRUCTIONS

Caution: Measure all voltages to verify applied voltage does not exceed the voltage rating of the unit. Reference the Expected System Voltages chart below. Improper installation voids the warranty.
NOTE: Suitable for use on a circuit capable of delivering not more than 100,000 rms symmetrical Amperes. Recommended circuit breaker size is 20 Amps. This SPD contains no serviceable parts.

  1. Turn off the power at the main breaker or service disconnect before beginning installation.
  2. Remove front cover from the electrical panel.
  3. Determine the ideal mounting position of the SPD by orienting the unit as close as possible to the position of the circuit breaker selected for the SPD connection.
  4. Remove a 3/4” knockout in the electrical panel or drill a 3/4” NPT hole in the electrical panel.
  5. Feed all wires through the knockout hole in the panel and tighten the included 3/4” locknut to the SPD fitting.
  6. Connect the Ground wire (Green) to the Ground bus inside of the panel.
  7. Connect the Neutral wire (White) to the Neutral bus inside of the panel.
  8. Connect the (1) High Leg Phase wire (Red) to the load side of the 1-pole High Leg circuit breaker.
  9. Connect the (2) Phase wires (Black) to the load side of the 2-pole circuit breaker.
  10. If desired, secure the enclosure with appropriate anchors by using the mounting feet on the SPD enclosure.
  11. After all connections have been made and no hazards exist, replace panel cover and restore power.
