OPERATING MANUAL
This manual describes necessary points of caution when
you use this product, including installation, connection, ba-
sic maintenance procedures and detailed operations.
POINTS OF CAUTION
■
POWER INPUT
• Locate the power input rating marked on the product and
confirm its operational range as indicated below:
Rating 100 – 240V AC: 85 – 264V, 50/60 Hz,
approx. 9VA at 100V
approx. 12VA at 200V
approx. 13VA at 264V
Rating 24V DC: 24V ±10%, approx. 4W
• Supplying any level of power other than specified above
can damage the unit or the power source.
• Power supply start-up characteristics must reach within 5
seconds to the operational voltage range of the unit.
• Power cables and signal I/O cables for the unit must be
located separately.
• Power cables and signal I/O cables for the unit should not
be bundled together.
• To increase noise resistance of the power input wires,
twist the strands before connecting.
■
GENERAL PRECAUTIONS
• Before you remove the unit, turn off the power supply and
I/O signal for safety.
• Do not disassemble or modify the unit in any way. Doing
so may result in a fire or an electrical shock.
• Do not block the unit’s ventilation openings or use it in
areas where heat accumulates.
Additionally, do not store or use it under high-tempera-
ture conditions.
• Do not use this unit in an environment where flammable/
corrosive gases are present.
• Do not store or use this unit in locations subject to direct
sunlight, or where excessive dust, dirt or metal particles
are present.
• This unit is a precision instrument. Do not store or use it
where large shocks or excessive vibration can occur.
• Do not store or use this unit in environments subject to
chemical evaporation (such as that of organic solvents),
or where there are chemicals and/or acids present in the
environment.
• Do not use paint thinner or organic solvents to clean this unit.
• Observe the environmental conditions when using this unit.
• Wait at least 30 seconds before turning on the power sup
-
ply after it was tuned off.
■
ENVIRONMENT
• Indoor use
• This unit is designed to be mounted on a vertical panel. It
is not suitable for a slanted or a horizontal panel surface.
• Environmental temperature must be within -5 to +55°C
(23 to 131°F) with relative humidity within 5 to 90% RH
in order to ensure adequate life span and operation.
■
GROUNDING
• Be sure to determine in advance the most stable ground
-
ing point in the environment and earth the unit’s FG ter
-
minal and that of connected devices to it in order to pro-
tect the devices from dielectric breakdown.
• Grounding is also effective to eliminate noise that could
cause errors in the unit’s operation.
■
MINIMIZING NOISE INTERFERENCE TO ANALOG
SIGNAL CABLES
• Noise entering through the analog signal cables may
cause irregular measurement values, degradation of over-
all accuracy, and malfunction of the product. We recom-
mend that you would conduct wiring to the unit with the
following points of caution.
• Do not install cables (power supply, input and output)
close to noise sources (high frequency line, etc.).
• Do not bind the analog I/O cables together with those in
which noises are present. Do not install them in the same
duct.
■
DO NOT APPLY OVERRANGE INPUT
• Do not apply voltages exceeding ±15V across the voltage
input terminals to prevent damage.
• Do not apply currents exceeding ±100mA to the current
input terminals to prevent damage.
■
AND ....
• We recommend use of an UPS to supply power backups.
• 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 en-
dure it without breakdown, however, it may shorten ap-
propriate life duration.
