  A PWR LED on the front of panel turns green 

  A ALM LED turns off 

  B PWR LED remains off 

  B ALM LED remains off 

 

20. With A PWR LED green (normal operation) and A ALM LED off (normal state) 

—but with B PWR LED and 

B ALM LED off 

— test A ALM relay and contact terminals:  

 

Expect continuity (0Ω) between terminals C and NC 

 

Expect an open circuit (∞Ω) between terminals C and NO 
 

21. Repeat steps 17-20 to power up side B. A PWR and B PWR LEDs must both be green.  

NOTE: 

Dip switches on alarm card are not used and should remain in the off (up) position to prevent false 

alarming. 

22. Reinstall the cover to the front of the panel using a Phillips screwdriver. 

 

2.2.8 Installing fuses 

23. Install GMT fuse into panel in appropriate positions.  

24. For any positions without a GMT fuse, a dummy fuse must be inserted in its place. If a fuse is installed 

at a later time, remove the dummy fuse and retain for future use.  

25. To remove a dummy fuse, use a small pair of needle nose pliers or equivalent to pull it out of position.  

  

2.2.9 Alarm Terminals  

26. The alarm terminals are located in the rear center of the panel. Refer to Fig. 2-8. 

 

a.  It is possible to use a short, manual wire-wrap tool to install alarm wiring after securing the panel to 

the rack. As an alternate to wire wrap, TE Connectivity insulation displacement connector, part 
number 3-640428-3, can be used to connect to the alarm terminals.
