1. Safety Precautions
For safe and correct usage, read the following precautions carefully before using the
indicator.
Grounding
Earth ground the indicator by connecting the earth ground terminal located on the rear
panel to the earth, to prevent a fire, electrical shock or indicator malfunction.
Do not share the ground line with other electrical power equipment.
Appropriate power cable
Use a power cable appropriate to the supply voltage and current used. Using an
inappropriate cable may cause electrical leakage or a fire.
Connect the power cable to the terminals firmly using compression lugs.
Fuse replacement
A fuse is provided to protect against a short circuit and possible fire hazard.
The indicator is equipped with various protection circuits and the fuse should not burn out
under normal operations.
If the fuse burns out, the internal circuits may have been damaged by surges. Do not try to
replace the fuse. Contact the nearest A&D dealer.
Avoid water and moisture
The indicator is not water-resistant.
Securing the front panel to the control panel using the accessory panel mount packing will
provide the indicator with IP-65 protection.
Avoid an environment with flammable gases
Do not use the indicator in places where flammable gases are present.
Indicator overheat
To prevent the indicator from overheating, allow appropriate clearance between the
peripheral devices.
If the ambient temperature exceeds the specified operating temperature, use a fan to cool
the environment.
