2.15 2350A OPTIONS
The following board configurations are optional
for the Model 500 GC with 2350A Controller.
2.15.1 The COM4A Board
1. To add four additional communications
ports 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 ma ke 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.
SERIOUS PERSONAL INJURY OR DEATH POSSIBLE
Before removing the unit cover from the GC Controller, make certain the power
supply switch is OFF and the AC power cord is disconnected. Observe all safety
precautions when you are working in a hazardous environment.
Failure to observe all safety precautions could result in serious injury or death.
