Note
To prevent damage to the panel and screws, do not overtighten
the screws.
The recommended torque for this product is 0.3 N·m to 0.5 N·m
(about half the normal torque).
Tighten the two screws evenly.
Installation position
Protective sheet
If installing the unit at the panel edge, choose an installation position where there is sufficient space for wiring work.
Optional unit
There is a protective sheet covering the LCD screen to prevent scratching during panel installation. Please remove the sheet
before using the meter. When removing the sheet, the LCD may turn on due to the static electricity generated. This is not
abnormal; the LCD will turn off after a short time.
Turn the auxiliary power supply off before attaching the optional unit. If attached with the power on, the main unit will not
recognize the optional unit. To remedy this, turn off/restart the auxiliary power supply or execute the “instrument restart” operation.
