3.2.2 Connecting Factory Power Supply with Main Power Switch
Preparations
Check that the power voltage of the factory falls within the voltage range shown on the label of the
step-down transformer.
Use of captyre cable (Oil-resistant) is recommended for the power cable.
In order to fix the cable securely with the cable gland, prepare a cable with outer size of 18.5 to 20.5
mm.
It is recommended to use a yellow-and-green spiral stripe coating wire for the ground cable.
The conductor size should be equivalent to the supply power cable.
Use an H sleeve to avoid trouble caused by raveled core.
