INSTRUCTION MANUAL
This manual describes necessary points of caution when
you use this product, including installation, connection and
basic maintenance procedures.
POINTS OF CAUTION
■
CONFORMITY WITH EU DIRECTIVES
• This equipment is suitable for Pollution Degree 2, Meas-
urement Category II (input, transient voltage 2500V) and
Installation Category II (transient voltage 2500V). Prior
to installation, check that the insulation class of this unit
satisfies the system requirements. Insulation class of this
unit is as follows.
Input to power
Reinforced insulation (300V)
Output 1 or output 2 to power Basic insulation (300V)
Input to output 1 to output 2 Basic insulation (300V)
• 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 requirements. Failure to observe these re-
quirements may invalidate the CE conformance.
• The actual installation environments such as panel con-
figurations, connected devices, connected wires, may af-
fect 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 conform-
ity.
• Install lightning surge protectors for those wires connect-
ed 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, 47 – 66 Hz,
≤ 3VA at 100V AC
≤ 4VA at 200V AC
≤ 5VA at 264V AC
24V DC rating: 24V ±10%, ≤ 3W
11 – 27V DC rating: 11 – 27V, ≤ 3W
110V DC rating: 85 – 150V, ≤ 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 10 to 85% 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.
■
AND ....
• The unit is designed to function as soon as power is sup-
plied, 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 ap-
propriate life duration.
