ETER
While holding the meter in place, push the panel latch over the rear of the
meter so that the tabs of the panel latch engage in the slots on the case. The
panel latch should be engaged in the farthest forward slot possible. To achieve
a proper seal, tighten the latch screws evenly until the meter is snug in the panel
(Torque to approximately 7 in-lbs [79N-cm]). Do not over-tighten the screws.

Installation Environment

The meter should be installed in a location that does not exceed the operating
temperature and provides good air circulation. Placing the meter near devices
that generate excessive heat should be avoided.
The bezel should only be cleaned with a soft cloth and neutral soap product.
Do NOT use solvents. Continuous exposure to direct sunlight may accelerate
the aging process of the bezel.
Do not use tools of any kind (screwdrivers, pens, pencils, etc.) to operate the
keypad of the meter.

Timer Input Logic Jumper

One jumper is used for the logic state of both timer inputs. Select the proper
position to match the input being used.
User Input Logic Jumper
One jumper is used for the logic state of all user inputs. If the user inputs are
not used, it is not necessary to check or move this jumper.
