is properly installed.
Please read and follow the installation instructions carefully.
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 120/240 VAC split phase circuits.

INSTRUCTIONS:

Caution: Measure all voltages to insure applied voltage does not exceed the voltage rating of
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 nipple through knockout hole then through nut, tighten nut securing the unit.
7. Connect the Ground wire (Green) to the Ground bus of the panel, 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 2 pole circuit 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 protective 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.
