1.3 POINTS OF CAUTION
■ CONFORMITY WITH EU DIRECTIVES
• This equipment is suitable for Pollution Degree 2, Measurement Category I (input, transient voltage 1500 V) and Installa-
tion Category II (transient voltage 2500 V). Reinforced insulation (input to power: 300 V) is maintained. Prior to installa-
tion, check that the insulation class of this unit satises the system requirements.
• The equipment must be installed such that appropriate clearance and creepage distances are maintained to conform to
CE requirements. Failure to observe these requirements may invalidate the CE conformance.
• Our products conforming to the EU Directives conforms to the standards required based on the premise that they are built
into various equipment, apparatus or control panels to use. Because the EMC performance depends on the congura-
tion, wiring or arrangement of the equipment, apparatus and control panels you build, it is necessary for you to make
such equipment, apparatus or control panels to conform nally to the CE Marking by yourselves.
This product conforms to the EMC Directive for electrical and electronic apparatus intended for use in industrial environ-
ments. If it is used in the residential environments, it may cause radio interference, and the user is requested to take
appropriate measures.
■ ENVIRONMENT
Install the unit within the installation specications.
• Indoors use.
• Environmental temperature must be within -10 to +55°C (14 to 131°F) with relative humidity within 30 to 90% RH without
condensing.
• Altitude up to 2000 meters.
• Provide sufficient space around the unit for heat dissipation.
• Mount the unit to a panel between 1.6 and 8 mm thick.
• Install the unit in a well-ventilated place in order to prevent internal temperature rise.
• Refer to “PANEL CUTOUT” to install several units. In mounting the unit with other equipment side by side, provide suf-
cient space between them, according to the dimensions in the panel cutout.
• Do not use the unit under the following environments:
– Where the unit is exposed to direct sunlight, rain or wind. (The unit is not designed for outdoor use.)
– Where condensation may occur due to extreme temperature changes.
– Where corrosive or ammable gas is present.
– Where heavy dust, iron powder or salt is present in the air.
– Where organic solvent such like benzine, thinner, and alcohol, or strong alkaline materials such like ammonia and
caustic soda may attach to the unit, or where such materials are present in the air.
– Where the unit is subject to continuous vibration or physical impact.
– Where there are high-voltage lines, high-voltage equipment, power lines, power equipment, equipment with transmis-
sion unit such like a ham radio equipment, or equipment generating large switching surges around the unit.
■ WIRING
• In order to prevent potential electric shock, wire the unit after turning off the power supply and making sure that the power
is not supplied to the cable.
• In order to enable the operator to turn off the power input immediately, install a switch or a circuit breaker according to the
relevant requirements in IEC 60947-2 and properly indicate it.
• Be sure to conrm the name and polarity of each terminal before wiring to the terminal block.
• Do not connect anything to unused terminals.
• Be sure to attach the terminal cover to prevent electric shock.
■ HANDLING CAUTIONS
• The unit is designed to function as soon as power is supplied, however, a warm up for 10 minutes is required for satisfy-
ing complete performance described in the data sheet.
• Use the unit within the noted supply power voltage and rated load.
• Clean the surface of the unit with wet soft cloth. Do not use organic solvent such like benzine, thinner and alcohol. Doing
so may result in deformation or discoloration of the unit.
• When abnormality is found such like smokes, unusual smell and abnormal noises coming from the unit, immediately cut
the power supply and stop using it.
