The flow computer includes two threaded end caps (covers). The front end cap includes a window
for viewing the HMI module, while the rear end cap provides access to the terminal plate for power

DANGER
EXPLOSION HAZARD: Never remove end cap(s) in a hazardous location. Removing end cap(s) in
a hazardous location could result in an explosion.
1. Remove the retaining clamp (if present). Grasp the end cap (front or rear).
Note
If you need more leverage to open or close an end cap than you can get with your hand,
you can place a long screwdriver or other appropriate tool across the two notches in the
end cap to act as a pry bar:
2. Unscrew the end cap turning it counter-clockwise until the end cap comes off. Set it aside in
a safe location.
