• When installing this unit within a control panel, please note that ambient temperature ofthis unit – not the ambient temperature of the control panel – must not exceed 55(131 ). Otherwise the life of electronic components (especially electrolytic capacitor)
may be shortened.
Note: Avoid setting this instrument directly on or near flammable material even though
the case of this instrument is made of flame-resistant resin.

Wiring Precautions

Caution• Do not leave bits of wire in the instrument, because they could cause a fire andmalfunction.
• When wiring, use a crimping pliers and a solderless terminal with an insulation sleevein which an M3 screw fits.
• Tighten the terminal screw using the specified torque. If excessive force is applied tothe screw when tightening, the screw or case may be damaged.
• This instrument does not have a built-in power switch, circuit breaker and fuse. It isnecessary to install a power switch, circuit breaker and fuse near the instrument.
(Recommended fuse: Time-lag fuse, rated voltage 250 V AC, rated current 2 A)
• For wiring of the AC power source, be sure to use terminals as described in thismanual.
If the AC power source is connected to incorrect terminals, the unit will be burnt out.
• Do not apply a commercial power source to the sensor which is connected to the
input terminal nor allow the power source to come into contact with the sensor.
• When using DC voltage and current input, do not confuse polarity when wiring.
• Keep the input/output wires and power lines separate.

Operation and Maintenance Precautions

Caution• Do not touch live terminals. This may cause an electrical shock or problems in operation.
• Turn the power supply to the instrument OFF when retightening the terminal orcleaning. Working on or touching the terminal with the power switched ON may result
in severe injury or death due to electrical shock.
• Use a soft, dry cloth when cleaning the instrument.
