Installation and Operation Manual 5

Proper installation is imperative to maximize the effectiveness and

performance of the Surge Protective Device (SPD). The installer should

follow the steps outlined in this instruction bulletin to ensure proper

installation. Read the entire instruction bulletin before beginning the

installation. These instructions are not intended to replace national or local

electrical codes. Check all applicable electrical codes to verify compliance.

Installation of surge suppressors should only be performed by qualified

electrical personnel.

CAUTION

LOSS OF SURGE SUPPRESSION

• During installation into an electrical system, SPDs must not be ener-

gized until the electrical system is completely installed, inspected, and

tested. All conductors must be connected and functional, including the

neutral. The voltage rating of the device and system must always be

verified before energizing the surge protective device.

• Any factory or on-site testing of power distribution equipment that ex-

ceeds the normal operating voltage, such as high potential insulation

testing, or any other tests where the suppression components will be

subjected to voltages higher than their rated turn-on voltage must be

performed with the suppressor disconnected from the power source.

The neutral connection at the SPD device must also be disconnected

prior to performing high-potential testing and then reconnected upon

completion of the test.

Failure to follow these instructions can result in injury or equipment

damage.

NOTE: Type 2 SPDs are designed for use on

the load side of the service entrance Overcur-

rent Protection Device (OCPD) only.
