2.2.10 Installing GMT Fuses 

 

ALERT! GMT fuses have a small inherent electrical resistance resulting in a small inherent power loss. 
For this reason, the GMT fuse manufacturer recommends that the load for GMT fuses up to and 
including 7.5A not exceed 80% of the fuse rating and that the load for GMT fuse sizes between 10A and 
20A not exceed 70% of the fuse rating. For example, the load for a 15A GMT fuse should not exceed 
10.5A (15A x.70 = 10.5A). 

31. Install GMT fuse into panel in appropriate positions.  

32. 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.  

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

  

2.2.11 Alarm Terminals  

34. The alarm terminals, nrgTEMP connectors, and nrgNET connectors are located in the rear center of the 

panel. Refer to Fig. 2-13. 
 
 
 

 

 

 

35. For the alarm terminals, 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. 

36. Two nrgTEMP connectors are available on the panel and accept the optional nrgTEMP probes.  

37. The Amphenol Network Solutions proprietary communication link, nrgNET, connects nrgSMART controller 

panels and nrgSMART panels. Legacy nrgSMART panels used a single cable with four conductors to 
provide power and data communication. CTRL and SENS panels use the same four conductor cable to 
provide data communication, with two of the conductors being unused.  

38. For nrgNET wiring used to daisy chain the controller panel to the attached nrgSMART panels do the 

following:  

a. 

Strip ⅜-in. of insulation away from the four conductor wires in the nrgNET cable  

b.  Insert the wires into the connector and tighten the screws to hold the wires in place making sure to 

connect the proper wire to the pins as illustrated in nrgNET Pin Outs Table 2.9.1 and in Fig. 2-34.  

c.  Insert the connector into the open end of the controller panel.
