Power Supply/Ground Connection
The above conditions are based on the premise that it is a three-phase AC power supply, and the cable specifications and setting methods may be within the above-specified ranges depending on the site conditions.
The ground cable must be yellow/green double color. Ground cable cannot be used for other purposes. In particular, the third type of grounding must be used (grounding resistance is 10Ω or less).
Insulation resistance point detection
If it is placed in a humid place during transportation or storage, measure the insulation resistance before installation. When voltage between main power supply and ground cable is 250V, the insulation resistance should be 20MΩ or more.
