case by firmly squeezing and pulling back on the side rear finger tabs. This
should lower the latch below the case slot (which is located just in front of the
finger tabs). It is recommended to release the latch on one side, then start the
other side latch.

unit is intended to be mounted into an enclosed panel. Prepare the panel cutout
to the dimensions shown. Remove the panel latch from the unit. Slide the panel
gasket over the rear of the unit to the back of the bezel. The unit should be
installed fully assembled. Insert the unit into the panel cutout.
To access the jumper and switches, remove the meter base from the meter
