Switched Off or The Area is Known To Be Non-Hazardous.
• The equipment was evaluated for use in the ambient tem-
perature and relative humidity as mentioned in ‘ENVI-
RONMENT’ section.
• The input and output wiring must be in accordance with
Class I, Div. 2 wiring methods and in accordance with the
authority having jurisdiction for use in these hazardous
locations.
■CONFORMITY WITH EU DIRECTIVES, UK LEGISLATION OR UL
• This equipment is suitable for Pollution Degree 2 and In-
stallation Category II (transient voltage 2500V). Rein-
forced insulation (signal input or output to power input:
300V) and basic insulation (signal input to output: 300V)
are maintained. Prior to installation, check that the insu-
lation class of this unit satisfies the system requirements.
• Altitude up to 2000 meters.
• The equipment must be mounted inside a panel.
• The equipment must be installed such that appropriate
clearance and creepage distances are maintained to con-
form to CE/UKCA/UL requirements. Failure to observe
these requirements may invalidate the CE/UKCA/UL
conformance.
• The actual installation environments such as panel con-
figurations, 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/UKCA
requirements in regard to the whole system and employ
additional protective measures to ensure the
CE/UKCA
conformity.
• Install lightning surge protectors for those wires connect-
ed to remote locations.

• Locate the power input rating marked on the product and
confirm its operational range as indicated below:
100 – 240V and 85 – 264V AC rating: 85 – 264V
(90 – 264V for UL), 47 – 66 Hz, approx. 3 – 5VA
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

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 ca-
bles, 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.
