User manual INTERMATIC UG40 MODULAR

[. . . ] All wire leads should be kept as short as possible to insure optimum operation. The internal disconnect switch and associated 100 KAIC fuses are the prime current protection devices for the UG40; therefore, lead wires may be connected to either a bus bar or a multi-pole breaker. If connected to a breaker, use a 30 to 100 amp breaker with the appropriate number of poles. Panel breakers will not trip from surge activity due to their inherent slow response. 4. NOTE: For installations connecting directly to bus bar, the UG40 must be less than ten feet (10') wire distance from the bus bar to qualify the internal disconnect switch and fuses as the primary overcurrent device in accordance with the NEC 10 foot rule 240-21(b). MOUNTING 1. [. . . ] Two Wire Opened Loop: Connect the feed wire to the Common ( C ) terminal and return wire to the Normally Closed (N/C) terminal. 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 ) terminal, one return wire to the Normally Opened (N/O) terminal and the second return wire to the Normally Closed (N/C) terminal. 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. N/O C N/C N/O C N/C Figure 8 N/O C N/C Figure 9 2 Figure 7 FINAL CHECKOUT PROCEDURE 1. CHECK each module for correct installation. They should sit flat against the back-plate with the locking clips firmly engaged in the T-slots on each side of the module. Make sure that the Disconnect Switch cover and the Dead-front panel have been replaced and properly secured. Turn the UG40 disconnect switch to the OFF position. Place alarm mode selector switch in the NORMAL position. RESTORE electric power to the UG40 circuit or equipment circuit. Turn UG40 disconnect switch to ON position. Check all indicator lights for proper illumination. 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 mode selector switch in SILENCE position: Audible alarm should sound. Return mode selector switch to normal position. Place and hold mode selector switch in TEST position. Audible alarm should sound and the alarm relay outputs should reverse state. Release the switch and allow it to return to the NORMAL position. OPERATION 1.
