NOTICE: This SPD should be installed by a licensed contractor in accordance with the National
and Local Electrical Codes and the following instructions.

APPLICATION

Type 1 SPD, Type 2 SPD for hardwired parallel installations on 277/480 VAC three phase circuits.

INSTRUCTIONS:

Caution: Measure all voltages to insure applied voltage does not exceed the voltage rating of
the unit. Improper installation voids the warranty.
NOTE: Suitable for use on a circuit capable of delivering not more than 100,000 rms symmetrical
Amperes.
This SPD Contains no serviceable parts.
1. Turn off the power at the circuit breaker or main disconnect before beginning installation.
2. Remove front cover from the panel.
3. Remove 3/4" knockout on side of panel box.
4. Make sure the leads are as short as possible with the ground wire being the shortest of all.
5. Unscrew locknut "A" from the Push-On Connector. The flexible conduit between the connectors can be cut
down to size as necessary. See the Illustrations Page on the back side of this document for more information.
6. Feed all wires and the connector through knockout hole then through nut, tighten nut securing the unit.
7. Connect the Ground wire (Green) to the ground bus making sure the ground wire is as short as
possible.
Ground Resistance Rule: Max ground resistance is 25 ohms, 5 ohms or less is optimum.
This cannot be an assumed value and must be measured to assure proper grounding.
8. Connect the Neutral wire (White) to the Neutral bus of the panel.
9. Connect the Phase wires (Black) to the line side or load side of the Phase A, Phase B and
Phase C, 3 pole breaker.
10. Securely mount the enclosure using the mounting feet located at each corner.
11. After all connections have been made and no hazards exist, replace panel cover and restore power.
12. This device features an internal protection that will disconnect the surge proctective component but will
maintain power to the load - now unprotected. If this situation is undesirable for the application, follow the
manufacturer's instructions for replacing the device.
Dry Contact Connection: This is a Form C Dry Contact Circuit, 0.9A, 240VAC maximum input.
Normally Open (NO)=Black Wire, Common (COM)= Red Wire, Normally Closed (NC)=White Wire.
Note: Remote Alarm Wires To Be Connected To Class 1 Circuits Only.
