•Locations such as laboratories where chemical changes may occur
•Locations outdoors at altitudes above 2,000 m
•Installation precautions
When installing the equipment, mount in accordance with the equipment external
dimensions, and allow adequate space around the equipment. For details of the external
dimensions and installation procedures, see “2 Installation”.
█
Power Supply
CAUTION
Always turn off the power before connecting or disconnecting cables. Leaving
power on may result in electric shock or equipment damage.
Before turning on the power, check to confirm that the power supply voltage
indicated on the equipment and in the specifications matches the voltage actually
supplied. Contact us if the specifications do not match. Using an unconfirmed
power supply may result in electric shock or equipment damage.
Always ground the equipment. Failure to ground the equipment may result in
electric shock or malfunctions.

iv
█
Usage and Operation Precautions
CAUTION
The equipment must always be calibrated before using for the first time or after
replacing a strain gauge-based transducer. Failure to calibrate the equipment may
result in incorrect measurement, equipment malfunction, and damage to peripheral
equipment.
Likewise, recalibrate the equipment if it has already been calibrated but gives
incorrect results.
CAUTION
Confirm that the wiring is correctly connected before attempting to use the
equipment. Incorrect wiring of the equipment may lead to incorrect measurements,
equipment malfunction, damage to peripheral equipment, and serious accidents.
CAUTION
Altering the settings while carrying out measurements using the equipment may
result in incorrect measurements, equipment malfunction, and damage to peripheral
equipment.
CAUTION
Do not subject the equipment to impact, for example, by striking it against objects.
Impact may damage the equipment and cause failures in the electrical circuits.
CAUTION
Do not press the front panel with excessive force or with sharp objects such as a
screwdriver. Doing so may damage the keys and affect durability and operations.
CAUTION
Do not detach the case cover, peel off the panel sheet, or otherwise attempt to
disassemble the equipment. Doing so may damage the case or panel sheet and
affect durability and operations.
CAUTION
Before turning on the power, check to confirm that the power supply voltage
indicated on the equipment and in the specifications matches the voltage actually
supplied. Contact us if the specifications do not match. Using an unconfirmed power
supply may result in electric shock or equipment damage.
CAUTION
This equipment is not fitted with a power switch. Attach a circuit breaker if necessary.
If a circuit breaker is attached, position it within easy reach from the equipment
operating position.
CAUTION
If dust or liquid adheres to the main unit, turn off the power, then wipe clean using
a soft, dry cloth.
The equipment is shipped with a clear protective sheet affixed to the front panel.
Remove the clear sheet before use.

2.1.1 Control Panel Installation Procedure
When mounting the equipment in a control panel, use the panel mounting brackets provided
If the equipment is to be used in an environment where water droplets or dust may be present,
insert the panel mounting seal provided between the equipment and the control panel
(cabinet). The front panel has a dust and waterproof construction equivalent to IP65 when the
panel mounting seal is used.
1. Cut out a hole in the control panel in accordance with the panel cutting dimensions.
2. Fit the front panel seal provided on the front of the main unit.
3. Insert the main unit from the front of the control panel, and seat the seal in place.
4. Attach the panel mounting brackets to the sides.
5. Tighten the mounting bracket screws from the rear of the control panel to secure it
place.
•When installing the equipment, refer to the following equipment dimensions, and allow
adequate space around the equipment based on the panel cutting dimensions.
