 Conversion Process

Use the following process to retrofit a 2350 GC 

Controller to a 2350A GC Controller.

1. At the GC Controller site, remove the 

Controller enclosure's front panel. 

(a) For the explosion-proof Controller, the 

front panel is secured by 16 screws. 

Remove those screws first. 

(b) Then carefully lower the front panel on 

its bottom hinges. The front panel is 

heavy, so make sure it does not drop and 

cause damage. 

(c) For the rack mount Controller, the rear 

of the enclosure is open; it allows access 

for most field wiring procedures without 

removing the enclosure. 

2. Locate the GC Controller's Terminal Board 

for Field Wiring (TB). The TB is attached to 

the GC Controller's card cage assembly, 

facing the enclosure's front panel. (In the 

rack mount Controller, the TB faces 

outward toward the rear of the enclosure.) 

3. Loosen the six screws that secure the TB. 

Then unplug the TB from its connections at 

the back, top of the board. 

when you are working in a hazardous environment. 
Failure to observe all safety precautions could result in serious injury or death.
