Troubleshooting

Mounting with the panel mount adapter

•Install the product as shown below.

•Insert panel mount adapter B into section A of panel mount adapter A.
Push panel mount adapter B from behind until the display is fixed onto the panel.
The pin of panel mount adapter B engages the notched part of panel adapter
section A to fix the display.

Wiring

•Connections should only be made with the power supply turned off.

•Use separate routes for the product wiring and any power or high voltage
wiring. Otherwise, malfunction may result due to noise.

•Ensure that the FG terminal is connected to ground when using a commercially
available switch-mode power supply. When a switch-mode power supply is
connected to the product, switching noise will be superimposed and the
product specification can no longer be met. This can be prevented by inserting
a noise filter, such as a line noise filter and ferrite core, between the switch­mode power supply and the product, or by using a series power supply instead
of a switch-mode power supply.

Connecting the wiring

•Use suitable crimp terminals for connection to the terminal block.

•Attention should be paid to the terminals to avoid short circuits.
