Installation Instructions
1. Insure that all power is removed before beginning installation. A qualified licensed electrician shall install all electrical
connections.
2. The SPD is provided in the enclosure type listed below. NEMA 12 enclosures are suitable for use in indoor installations. NEMA
3R, NEMA 4 or NEMA 4X enclosures are suitable for use in indoor or outdoor installations.
4. The SPD has obtained the short circuit current rating shown below.
Circuit Ampacity Limitations. Representative samples of these products have been investigated by Underwriters Laboratories,
Incorporated to withstand, without exposing live circuits or components at system voltages and fault currents of up to the rating
shown above, as described in the Standard for Safety, Surge Protective Devices (SPDs), Standard 1449, Third Edition, released (2009).

3. Determine where the SPD is to be mounted, allowing for minimum length of wire between itself and the input power terminals
of the service panel. Punch or cut the proper hole size in the side of the SPD closest to the knockout to be utilized in the service
panel. Drill mounting holes in wall at location picked for SPD next to service panel using mounting dimensions shown in the
tables on the “Dimensional Information” pages in this manual. Mount surge suppressor using the hardware listed.
