Removing/Replacing the Coin Cell Battery

Insert the new coin cell battery in the slot. The positive side (+) must be on top.

CAUTION

When inserting the SRAM coin cell battery push the battery gently into its slot until it

stops. The battery should slide in easily. Do not use excessive force.

To replace the HMI module, line up the printed circuit board (PCB) with the slot on the back

and gently press it back on. Tighten the four captive fastening screws with a torque of 4 to 6

in-lbs (0.5 to 0.7 N-m).

Carefully align the end cap threads with the threads of the enclosure and replace the front

end cap. Screw the end cap clockwise (eight full turns) until it is tightly sealed to the

enclosure. End caps must have at least 8 full threads engaged upon reassembly.

Note

If you need more leverage, place a long screwdriver or other appropriate tool across the two

notches in the end cap to act as a pry bar.

If applicable, tighten the retaining clamp onto the end cap using a 3mm hexagonal wrench.

When tightening, torque to 10 to 12 in-lbs (1.1 to 1.4 N-m).
