User manual INTERMATIC 158PG11842-1

[. . . ] 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. A form C relay for remote alarm indication, audible trouble alarm with test and silence switch are also standard equipment. The system is comprised of three sections; outer housing, cover plate and inner module. [. . . ] Refer to INVERTED INSTALLATION section below for information regarding the inverted installation. Align the SPD to allow 1/16" between the SPD cover plate and the cover of the panelboard. The SPD should be secured to a flat vertical surface that can support the weight of the device. Temporarily fasten the SPD to the vertical surface and mark the location where a hole for the collar or conduit will enter. Refer to Table 1 for acceptable locations on the bottom of the Outer Housing that can be drilled for wire entry. 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. See Table 2 for recommended wire and breaker sizes. Use of a dedicated circuit breaker is optional since the SPD has integral overcurrent fusing. Lugs accept wire sizes from 10 AWG to 2 AWG. Keep all leads as short and straight as possible, avoiding sharp 90 degree bends. Increase wire size when lead length is extended. 10 AWG 30 AMP 8 AWG 40 AMP 6 AWG 50 AMP 4 AWG 60 AMP 2 AWG 80 AMP Table 2 INVERTED INSTALLATION (under panelboard) 1. Turn OFF and LOCK the electric power supply to the panelboard. SELECT the location where the Surge Protection Device (SPD) will be mounted below the electric panel. Position the SPD adjacent to the electric panel with the bus bars pointed toward the panel. NOTE: The labels on the inner housing will be inverted. Align the SPD to allow 1/16" between the SPD cover Plate and the cover of the panelboard. The SPD should be secured to a flat vertical surface that can support the weight of the device. ALARM RELAY CONNECTIONS Violet - n/c Brown - c Orange - n/o Normal operating condition - relay energized Violet - n/c Brown - c 3. Temporarily fasten the SPD to the vertical surface and mark the Orange - n/o location where a hole for the collar or conduit will enter. [. . . ] Return the switch to the NORMAL position. The ALARM SWITCH should be in the NORMAL position for standard operating conditions. The COVER PLATE must be in position with all bolts secured to prevent access by unauthorized personnel. The PROTECTION MODE indicator lights should be ON. [. . . ]
