User manual INTERMATIC PG3000-3500

[. . . ] All wire leads should be kept as short as possible to insure optimum operation. The internal Ferraz Shawmut VSP fuses are the prime current protection devices for this SPD; but safety and good wiring practice suggests that lead wires be connected to a multi-pole breaker. Use a 60 to 100 amp breaker with the appropriate number of poles. Panel breakers will not trip from surge activity due to their inherent slow response. [. . . ] The contact will open during an alarm condition. Two Wire Opened Loop: Connect the feed wire to the Common ( C ) wire and return wire to the Normally Closed (N/C) wire. During normal operation, the contact will be opened between C and N/C. The contact will close during an alarm condition. Three Wire Supervised Loop: Connect feed wire to the Common (C) wire, one return wire to the Normally Opened (N/O) wire and the second return wire to the Normally Closed (N/C) wire. During normal operation, the contact will be closed between C and N/O and opened between C and N/C. An alarm condition will reverse the condition. Consult the instructions for your specific monitoring system for additional information.

While these units have internal fusing, it is recommended that a 60 to 100 amp breaker be used as a disconnect. Refer to installation instruction number 4 on page 1. 2 Orange - n/o Alarm condition - relay not energized FINAL CHECKOUT PROCEDURE 1. Make sure that the Dead-front panel has been replaced and properly secured by replacing all bolts. Make sure that the cover is closed and secured by all bolts. Place alarm Alarm Switch in the NORMAL position. RESTORE electric power to the PG Series circuit or equipment circuit. Check all PROTECTION STATUS Line indicator lights for proper illumination. Confirm that the PROTECTION STATUS Alarm indicator if OFF. Check output continuity for the alarm relay. (a) Common to Normally Open = 0 ohms; (b) Common to Normally Closed = greater than 10 M ohms. Place Alarm Switch in SILENCE position: Audible alarm should sound. Place and hold Alarm Switch in TEST position. Audible alarm should sound and the alarm relay outputs should reverse state. [. . . ] Upon a determination by Intermatic that the Product is defective, Intermatic shall correct any defect in material or workmanship by, at Intermatic's option, either repairing or replacing the Defective Product. Any repair, including both parts and labor, shall be at Intermatic's expense. The foregoing remedies are the purchaser's exclusive remedies for a breach of warranty.
