1. SAFETY PRECAUTIONS
For safe and correct usage, read the following precautions carefully before using the indicator.
Precautions on designing
WARNING
● Provide an external safety circuit to the indicator so that the safety of the whole system can be
secured even if errors occur in the external power supply or in the indicator.
Precautions on installation
WARNING
● Do not use the indicator in the following environment:
- where the temperature and the humidity exceed the specifications
- where corrosive gases or flammable gases exist
- where the indicator gets wet with oil, chemicals or water
Please note that securing the indicator to the control panel will provide the indicator outside of the
control panel the IP65 protection.
● When installing or removing the indicator, be sure to turn off all the external power supplies used
beforehand.
Precautions on wiring
WARNING
● When wiring the indicator, be sure to turn off all the external power supplies used beforehand.
● When wiring is complete, be sure to attach the terminal block cover provided with the indicator.
● Be sure to earth ground the indicator.
CAUTION
● Do not clamp control wires or communication cables with power lines, or do not place them close to
power lines.
● Place the load cell cable sufficiently away from high frequency circuits such as high voltage power
lines and inverter load circuit.

●Multidrop connection
When a master and some AD-4401As are connected by a 1:n multidrop connection, a different slave
address (rS
F-09) is assigned to each AD-4401A. When the master sends a command by adding the slave
address (@ 0 1 to @ 9 9) at the beginning, the AD-4401A with the matching slave address sends a
response by adding the slave address (@ 0 1 to @ 9 9) at the beginning.
