3.1.1.Installation and Precautions

The AD-4405 weighing indicator is a precision electronic instrument. Handle the indicator carefully.

The operating temperature is -10°C to +40°C (14°F to 104°F).

Do not install the scale in direct sunlight.

Mis-operation or other problems may be caused by an unstable power source including momentary power failure or instantaneous noise. Use a stable power source.

Do not connect the power cord before the installation has been completed. Verify that the local voltage and receptacle type are correct for your scale.

Use shielded cable for all connections. Connect the cable shields to the shield terminal or case as an earth terminal.

Earth ground the indicator. Do not join the earth ground line with other electrical power equipment. There is an earth ground terminal at the power cord receptacle. Do not install the indicator in a place where it is apt to be charged with static electricity, or where the relative humidity is lower than 45%RH. Plastic and insulating materials are apt to be charged with static electricity.

3.1.2.The Load Cell Connections

Connect the load cell wires to the connector (receptacle), at the rear panel, using the accessory load cell plug.

It is possible to connect a 4 wire cable provided that pins 1-2 and pins 3-4 are shorted, if the distance between the indicator and the load cell is shorter than 5m. The output voltage of a load cell is a very sensitive signal. Space the load cell cable away from any noise source.

It is possible to connect four 350ohm load cells.

The load cell drive is 5VDC 5% between EXC+ and EXC-, the maximum current 60mA.
