Caution with respect to Export Trade Control Ordinance

To avoid this instrument from being used as a component in, or as being utilized in the manufacture

of weapons of mass destruction (i.e. military applications, military equipment, etc.), please

investigate the end users and the final use of this instrument.

In the case of resale, ensure that this instrument is not illegally exported.

Caution

Procedures which may lead to dangerous conditions and

cause death or serious injury, if not carried out properly.

Procedures which may lead to dangerous conditions and cause

superficial to medium injury or physical damage or may

degrade or damage the product, if not carried out properly.

Caution

This instrument is intended to be used under the following environmental conditions

(IEC61010-1): Overvoltage category , Pollution degree 2

Ensure the mounting location corresponds to the following conditions:

• A minimum of dust, and an absence of corrosive gases

• No flammable, explosive gases

• No mechanical vibrations or shocks

• No exposure to direct sunlight, an ambient temperature of -5 to 55 (23 to 131 )

that does not change rapidly, and no icing

• An ambient non-condensing humidity of 35 to 85%RH

• No large capacity electromagnetic switches or cables through which large current is flowing

• No water, oil or chemicals or where the vapors of these substances can come into

direct contact with the unit

• When installing this unit within a control panel, take note that ambient temperature of

this unit 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.

Caution

• Do not leave wire remnants in the instrument, because they could cause a fire or a malfunction.

• When wiring terminals, use ferrules with an insulation sleeve and crimping pliers made

by Phoenix Contact GMBH & CO. applicable to terminals.

• Tighten the terminal screw using the specified torque. If excessive force is applied to

the screw when tightening, the screw or case may be damaged.

• This instrument has no built-in power switch, circuit breaker or fuse. It is necessary to

install them near the instrument.

(Recommended fuse: Time-lag fuse, rated voltage 250V AC, rated current 2A)

• For wiring of AC power source, be sure to use exclusive terminals as described in this

manual. If AC power source is connected to incorrect terminals, the unit will burn out.

• For a 24V DC power source, do not confuse polarity when wiring.

• For DC voltage and current inputs, do not confuse polarity when wiring.

• 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.

• Keep the input/output wires and power line separate.

Caution

• Do not touch live terminals. This may cause electric shock or problems in operation.

• Turn the power supply to the instrument OFF when retightening the terminal and

cleaning. Working or touching the terminal with the power switched ON may result in

severe injury or death due to Electric Shock.

• Use a soft, dry cloth when cleaning the instrument.

(Alcohol based substances may tarnish or deface the unit.)

• As the display section is vulnerable, do not strike or scratch it with a hard object or

press hard on it.
