POINTS OF CAUTION
■CONFORMITY WITH EU DIRECTIVES
• This equipment is suitable for Pollution Degree 2, Instal-
lation Category II (transient voltage 2500V) and Meas-
urement Category II (contact output, transient voltage
2500V). Reinforced insulation (analog input or contact
input or contact output or network interface to power to
FE: 300V) and basic insulation (analog input each other
or contact input or network interface to contact output
each other: 300V) are maintained. Prior to installation,
check that the insulation class of this unit satisfies the
system requirements.
• Altitude up to 2000 meters.
• Do not share the grounding point of PE (Protective Earth)
of other devices with FE (Functional Earth). Handle as
signal ground.
• 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.
• In order to enable the operator to turn off the power in-
put immediately, install a switch or a circuit breaker ac-
cording to the relevant requirements in IEC 60947-2 and
properly indicate it.
■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, 50/60 Hz,
approx. 7VA at 100V AC
approx. 10VA at 240V AC
24V DC rating: 24V ±10%, approx. 6W
110V DC rating: 85 – 150V, approx. 6W
• 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, signal I/O cables and communication 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 signals 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 15 seconds before turning on the power sup-
ply after it was turned 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 30 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 FF
terminal and that of connected devices to it in order to
protect the devices from dielectric breakdown.
• Grounding is also effective to eliminate noise that could
cause errors in the unit’s operation.
■MEMORY CARD
• Do not turn off the power supply to the unit or reset it
during data recording or alarm history recording. The
memory card may be destroyed.
• Observe the described procedure when you need to re-
place the memory card during recording.
• Confirm the sides and the connector position of the mem-
ory card when inserting one to the card slot.
• Do not touch the metal terminal with your hands or me-
tallic tools.
• Memory cards have a life span. Back up your important
data.
■LCD PANEL
• The LCD panel’s liquid contains an irritant. If the panel
is damaged and the liquid contacts your skin, rinse imme-
diately the contact area with running water for at least 15
minutes. If the liquid gets in your eyes, rinse immediate-
ly your eyes with running water for at least 15 minutes
and consult a doctor.
• The following phenomena are LCD characteristics, and
NOT a product defect:
- LCD screen may show uneven brightness depending
upon displayed images or contrast settings.
- The LCD screen pixels may contain minute black-and-
white-colored spots.
- The color displayed on the LCD screen may appear dif-
ferent when seen from outside the specified viewing an-
gle.
- When the same image is displayed on the screen for a
long time period, an afterimage may appear when the im-
age is changed. If this happens, turn off the unit and wait
for a while before restarting it.
• To prevent an afterimage:
- Set the screensaver when you plan to display the same
image for a long time period.
- Plan to change the screen image periodically so that the
same image does not remain for the long time period.
■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 close to noise sources (high frequen-
cy line, etc.).
• Do not bind the analog input 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 to terminals V –
COM, A – C and B – C to prevent damage. Do not apply
currents exceeding ±30mA to terminals I – COM and B
– C to prevent damage.
■INTERNAL CLOCK
• The internal clock data is stored in memory powered by a
backup battery while the unit is without external power
supply.
• The data will be reset to its default status when the bat-
tery is used up while the unit is left without power sup-
ply for a long time period. The clock adjustment will be
necessary once the power is restored.
• Once the power is restored, the unit starts recharging the
battery. It will be full in approximately in 36 to 48 hours.
• Battery backup: approx. one month
■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.

■CAUTION
• Degree of protection, IP65 is applicable to the front panel
of the unit with single mounting according to the speci-
fied panel cutout. Not applicable in case of re-mounting.
After installation ensure waterproof of the mounting.
• Install the unit to vertical panel so that its function but-
tons are at the bottom side. Installing by other direction
will cause degradation of life span or performance due to
rise of the internal temperature.
• Ensure that there is sufficient space for ventilation inside
a panel. Do not install above the devices that generate
high heat such as heaters, transformers or resistors. Ob-
serve at the minimum of 30 mm (1.2”) in all directions for
maintenance purpose.
■HOW TO MOUNT THE UNIT ON A PANEL
1) Remove the mounting brackets.
2) Remove the terminal cover and insert it into the panel
cutout prior to insertion of the unit.
3) Insert the unit into the panel cutout. The watertight
packing must be in place to conform degree of protection,
IP65. Do not remove it.
4) Hang the hooks of the mounting brackets at the square
holes on the upper and bottom side of the unit. Tighten
screws of the brackets until the unit is fixed to the panel.
