4 Wiring
This chapter describes how to connect load cells and power sources.
4.1 Precautions for wiring
-
Connect wires with the device power of.
-
Do not connect the power supply until all installation and wire connections are
complete. The device has no ON/OFF switch for power supply.
-
Do not drop the device or subject it to impacts because the terminal block of the rear
panel is made by resin.
-
Install and use the attached acrylic cover for the terminal boards.
-
The tightening torque for screws on the terminal board are given in the table below.
Terminal board
Tightening torque of screws
Power supply
1.4 Nm
Load cell
0.6 Nm
-
Applicable solderless terminals are as follows.
Terminal board
Solderless termi-
nal width
Applicable solderless terminal
Power supply
9.0 mm or less
1.25-4, 2-4 or Y type 1.25-4 and 2-4
Load cell
6.2 mm or less
1.25-3 or Y type 1.25-3.5
-
Isolate cables connected to the unit from such noise sources as dynamic power lines
and control I/O.
-
As dedicated wiring is used for conduit wiring, avoid sharing it with other lines.
-
Be sure to connect a grounding wire. Grounding should be D-class single grounding.
Avoid sharing it with other power supply groundings.
-
Use shielded cable for connection with external control I/O, and connect the shield
with the F.G terminal of the power supply terminals.
4.2 Connection with load cells
The CSD-918 needs to be connected to a load cell to facilitate weighing.
Examples of CSD-918 connected with load cells are given below.
Note:
When a tension or tension/compression load cell is used in the direction of the tension
and the + direction is displayed, connect the load cell input + to terminal B and the load
cell input – to terminal D, respectively.
