authority having jurisdiction for use in these hazardous
locations.

■ CONFORMITY WITH EU DIRECTIVES OR UL

•This equipment is suitable for Pollution Degree 2 and
Installation Category II (transient voltage 2500 V). Re­inforced insulation (signal input or output 1 or output 2
to power input: 300V) and basic insulation (signal input
to output 1 or output 2: 300V) are maintained. Prior to
installation, check that the insulation class of this unit
satisfies the system requirements.

•Altitude up to 2000 meters.

•The equipment must be mounted inside a panel.

•Insert noise filters for the power source, input and output

connected to the unit. COSEL Model NAC-04-472, TDK
Model ZCAT 3035-1330 or equivalent is recommended.

•The equipment must be installed such that appropriate
clearance and creepage distances are maintained to con­form to CE/UL requirements. Failure to observe these
requirements may invalidate the CE/UL conformance.

•The actual installation environments such as panel con­figurations, connected devices, connected wires, may af­fect the protection level of this unit when it is integrated
in a panel system. The user may have to review the CE
requirements in regard to the whole system and employ
additional protective measures to ensure the CE conform­ity.

•Install lightning surge protectors for those wires connect­ed to remote locations.

■ POWER INPUT RATING & OPERATIONAL RANGE

•Locate the power input rating marked on the product and
confirm its operational range as indicated below:

100 – 240V AC rating: 85 – 264V (90 – 264V for UL),
47 – 66 Hz, approx. 4 – 6VA
24V DC rating: 24V ±10%, approx. 3W
11 – 27V DC rating: 11 – 27V, approx. 3W

110V DC rating: 85 – 150V (110V ±10% for UL), approx. 3W

■ GENERAL PRECAUTIONS

•Before you remove the unit from its base socket or mount
it, turn off the power supply and input signal for safety.

■ ENVIRONMENT

•Indoor use.

•When heavy dust or metal particles are present in the

air, install the unit inside proper housing with sufficient
ventilation.

•Do not install the unit where it is subjected to continuous
vibration. Do not subject the unit to physical impact.

•Environmental temperature must be within -5 to +55°C
(23 to 131°F) with relative humidity within 30 to 90% RH
in order to ensure adequate life span and operation.

•Be sure that the ventilation slits are not covered with ca­bles, etc.

■ WIRING

•Do not install cables close to noise sources (relay drive
cable, high frequency line, etc.).

•Do not bind these cables together with those in which
noises are present. Do not install them in the same duct.

■ AND ....

•The unit is designed to function as soon as power is sup­plied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data
sheet.

•With voltage output, do not leave the output terminals
shortcircuited for a long time. The unit is designed to
endure it without breakdown, however, it may shorten ap­propriate life duration.
