SAFETY PRECAUTIONS FOR INSTALLATION
DANGER
The indicator complies with “ExdIIBT5X” specifications for Explosion protected
devices. Install and use the indicator in a proper place to avoid explosion.
Environments
•
•
•
•
•
•
•
•
•
•
•
•
Install and operate the indicator in Zone 1 or Zone 2. Never use in Zone 0.
Do not install the unit in direct sunshine.
Avoid vibration, sudden temperature changes, wind, water, or excessive
dirt.
Operate in environments with temperatures of between -5°C to 40°C and
humidity of between 45% and 85% R.H. (non-condensing).
Mount the unit on a solid frame or wall.
Installation work
Do engineering work and wiring in accordance with the requirements by
laws and regulations related to hazardous area devices.
Only a trained professional with good knowledge of explosion protected
devices should be allowed to perform the installation work.
Grounding
To avoid electrical shock and accident from static electricity, plug the power
cable into a properly wired earth grounded receptacle, or ground the “E”
terminal of Power source terminals before connecting anything else to any
of the instrument binding posts.
Do not share grounding with other units that create electrical noise.
Power supply
The power source should be 100 VAC +10%/-15% specification; with a
frequency of 50 or 60 Hz. Use a stable power source free from
instantaneous dropout or noise. Sharing a power line could result in
malfunctioning.
Do not turn the power on until all the installation work has been completed.
Before opening the front panel
Turn the power off (primary power) and wait approximately ten minutes for
the electrical charge to dissipate before opening the front panel.
CAUTION
The front panel door is thick and heavy. Be careful not to catch your finger in
the door.
SAFETY PRECAUTIONS DURING OPERATION
DANGER
Disassembly/ Modification
Never try to disassemble or modify the unit. That may cause an explosion.
When opening the Front panel.
Cut off the main power supply and wait 10 minute before opening the front
panel to avoid an explosion.

CAUTION
The front panel door is thick and heavy. Be careful not to catch your finger in the
door.

2-2
2-2 Wiring
Open the front panel door removing screws on the front panel, and connect a power cable, load cell
cables, and control signal cables to the terminals inside the case. Follow the instructions below.
Cable used
Load cell
The use of a 6 wire shielded cable is recommended in order to reduce
weighing error. (When using a 4-wire cable, connect pin # 34 to # 35, and
pin # 36 to # 37.)
If the system requires two or more load cells, use an explosion-protected
type of summing box to input the signal into the indicator.
Control signal cable Use a shielded cable and connect its shield to pin # 40 (Frame ground).
