5.4.2 Cable Connection

Connect and install the terminal-treated cables to the terminal block.

*Connect the cables to the terminal block securely. A loose connection may cause incorrect

measurement. After connecting a cable, try to pull it to check whether it has been connected securely.

Referring to

combined converter's manuals of "Connections and Grounding"

, connect each cable to the

terminal block.

Tighten the screws of the terminal block tightly to ensure a secure connection

. A loose

connection may cause incorrect measurement.

After connecting a cable, try to pull it to see whether it has

been connected securely.

Figure 5.5 Connecting a Cable to Terminal Block

Phillips screwdriver

Terminal block

* The appropriate torque for tightening

the terminal board screw is 1.2 N.m.
