Note: 1. Terminals 2 and 3 and 10 are not internally insulated. Connect a relay with high contact reliability and insulation (with a minimum
load current of 0.3 mA) or a photocoupler with high insulation (with a residual voltage of 1 V max. and a current leakage of 0.1 mA
max.) to these terminals for external control. The use of an independent power supply is recommended for the Digital Panel Meter.
2. Terminal 8 is not used. Do not use this terminal for transmission of signals.

Safety Precautions
■ Precautions for Correct Use
Accessories (Order Separately)
Refer to Safety Precautions for All Digital Panel Meters.
Water-resistive Soft Front Cover
Mounting
Before mounting the Digital Panel Meter to a panel, attach the waterresistive soft front cover and mounting bracket to the Digital Panel
Meter properly so that the Digital Panel Meter will maintain IP51
water-resistive standards.
Recommended panel thickness is 1 to 3.2 mm.
Mount the Digital Panel Meter by attaching the mounting bracket supplied as an accessory from the rear of the Digital Panel Meter and
hooking the mounting bracket to the Digital Panel Meter securely.
Tighten the mounting screws by turning them clockwise with a tightening torque of 4 kgf·cm (0.39 N·m).
To dismount the Digital Panel Meter, loosen the screws and widen
the hooks.
Mounting
Adapter
Mount the Digital Panel Meter as horizontally as possible.
Soft Cover
Calibration
Calibrate the Digital Panel Meter regularly so that the Digital Panel
Meter can maintain processing accuracy.
Note: Be sure to use the Water-resistive Soft Front Cover and
mounting bracket together.
Use a standard signal generator with an accuracy of 99.99% min. for
calibration.
For the precise calibration methods, refer to the Instruction Sheet for
the Digital Panel Meter.
Control Power Supply
Use a control power supply with a ripple rate of 10% max.
ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
To convert millimeters into inches, multiply by 0.03937. To convert grams into ounces, multiply by 0.03527.
