2. Connecting method
2-1. Notes concerning to the connecting wires
● Be sure to set the power supply to OFF, when the connection will be made.
● Please do not put the plug of the AC power supply until the installation is completed.
There is no switch which switches power supply ON/OFF in the main body.
● Please separate the cable connected with the main body from the power supply line and noise source of
control I/O, etc., as much as possible.
● Conduit wiring should be the type of exclusive one, and avoid using with another line together.
● The grounding wire should be connected. Grounding should be the D class with single earth.
Please do not share with the grounding and the power supply system.
Please connect the grounding via the attached AC cable.
● Please use the shielded cable for the connection with the external control input and the contact output,
and also connect the shield with the shield terminal or the main body.
2-2. Connection with the load cell
Please connect the plug attached as a load cell connector with the receptacle in the rear panel to connect with
the load cell. Suitable plug : NJC-207-PF(by Nanahoshi) or equivalent.
① When the connecting cable is 6 wires method
② When the connecting cable is 4 wires method
The connection between the second of sensing input +/connector and the third of the sensing input -/connector should be short-circuited
near the main body of the load cell. It will not work as the 6 wires method when the short-circuit is made in the load cell connector.
In case of using with 4 wires method, the connection between No.1 - No.2 and No.3 – No.4 in the connector should be short-circuited.
When No.2 connectors and No.3 are used while opened, CSD-904-EX does not work normal operation.
