■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 use in a Pollution Degree
2 environment and in Installation Category II, with the
maximum operating voltage 300V. Basic insulation is
maintained between the input and output. Prior to in-
stallation, check that the insulation class of this unit sat-
isfies the system requirements.
• The equipment must be mounted inside a panel.
• Altitude up to 2000 meters.
• 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 conformity.
■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 – 63 Hz, ≥ 130VA
24V DC rating: 24V ±10%, ≥ 2.5A
■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 installation base inside proper housing and
ventilate it.
• Do not install the base where it is subjected to continuous
vibration. Do not subject the unit to physical impact.
• Environmental temperature must be within 0 to 55°C or
32 to 131°F (0 to 50°C or 32 to 122°F for AC power) with
relative humidity within 30 to 90% RH (30 to 85% RH
for AC Power) 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.
• When using M2 power, use a ferrite core close to the unit
for power line. Using ferrite core is enough to eliminate
noises, but turning the cable twice (1 round) as figure be-
low is recommended.
• Be sure to close the terminal cover for safety.
■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.
