[. . . ] INSTALLATION INSTRUCTIONS and OPERATIONS MANUAL PanelGuard® PG60 - PG80 - PG100 Series Electrical Panel Extension Hardwired Surge INTRODUCTION The PG60-80-100 Series is designed to be installed in very close proximity to the power bus of an electric distribution panel or electric panelboard. The PG60-80-100 Series offers peak surge amperage protection levels of 60 kA to 100 kA per mode. Provisions have been made with a reversible cover plate to keep the instructions and indicators in a user friendly position. Standard features include all mode protection, multimode LED indicators that show full protection, diminished protection and lost protection for all phases. [. . . ] Note that wiring for the remote monitoring relay enters separate from the AC power leads. Remove the SPD unit and drill a hole of sufficient size to accept the collar or conduit connector. Attach the collar or connector to the SPD outer cabinet and mount the unit with the collar or connector inserted into the knockout in the panelboard. Use the proper gauge wire to connect each of the lugs on the SPD to the appropriate points on the electric panel. Use of a dedicated circuit breaker is optional since the SPD has integral overcurrent fusing. The SPD can be connected through a breaker or direct tapped for Switchboard installations. Select a position for the connection that results in the shortest lead lengths between the SPD and the power bus. Leads should be kept as short as possible to insure optimum operation. Strip the ends of each lead 9/16" for the SPD terminal lugs and to proper length for the breaker used. Torque the lugs 35 to 50 inch pounds per UL 486 torque tightening requirements. NOTE: For safety, observe proper wire marking conventions; BLACK for HOT, RED for HOT HIGH LEG, WHITE for NEUTRAL, GREEN for GROUND. Route the wire lead bundle through the collar or connecter into the electric panel. the tral the If used, connect the NEUTRAL (white) to the neutral bus in electric panel. If installing at a main electrical panel, the neuand ground leads could terminate at a common bus bar in panel. Line to Line: 240v. ; Line to Neutral: 120v. ; Line to Ground: 120v.

NOTE: For HIGH LEG DELTA, make certain that the high leg is connected to the center bus bar position in the SPD. Alarm wires should be routed through a hole in the outer housing that is separate from the power leads. If the alarm relay is not used, leave the wires in the low voltage section, they will have no power and do not need to be capped. Refer to the alarm wiring drawings on page 3 or on the wiring label on the inner housing for wire designation. CHECK all connections for correct torque. G Line to Line: 480v. ; Line to Ground: 480v. INSTALLATION INSTRUCTIONS and OPERATIONS MANUAL 3 PG60-80-100 SERIES - V. 10-03 SUGGESTED WIRE and BREAKER SIZES Use the following table as a guideline for the PG60, PG80 and PG100 Surge Protection Devices. All models have integral overcurrent fusing and the use of a dedicated circuit breaker is optional. [. . . ] The COVER PLATE must be in position with all bolts secured to prevent access by unauthorized personnel. Periodic functional checks of the system as required by local codes or procedures are conducted by performing steps 9 and 10 of the FINAL CHECKOUT PROCEDURE. COVER PLATE INSTALLATION The cover plate has labels on the front and back. One side has the labels positioned for use when the SPD is located at the top of the electrical panel. The second side of the cover plate is used when the SPD is positioned at the bottom of the electric panel. [. . . ]
