The contrast of the display changes at view angle. Mount it at the position that is
easy to see.
Panel hole dimensions are as shown in the following figure.
It can be attached to a panel with thickness of 1.6 to 4.0mm.
For attachment of the basic device into the panel hole, attach according to the following procedure.
q
The attachment lug is installed in two holes of the top and bottom of the basic device. w Tighten the screws of the lug, and fix onto the panel.
When installing the optional plug-in module onto the basic device, install accoroding to the following procedure.

Three phase 4-wire system: Direct input
qAuxiliary power supply:
100-240VAC or VDC
wFuse: 0.5A
*1 For low-voltage circuits,
secondary-side grounding of
instrument-use voltage/current
transformers is not required.
*2 Connection to NC terminal is
prohibited.

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.
Note
qRemove the wire casing at the end of the
wire and solder to the rod terminal.
wWith the lever pushed in, insert the wire and
then release the lever to connect.
