(b) Ground Wiring
S
Do not share the ground wire with other devices, such as welding machines
or power tools. Separate the grounding cables from the wirings for power
tools.
S
Always use a ground wire that complies with technical standards on electri-
cal equipment and minimize the length of the ground wire.
Leakage current flows through the power regenerative unit. Therefore, if
the distance between the ground electrode and the ground terminal is too
long, potential on the ground terminal of the power regenerative unit will
become unstable.
S
When using more than one power regenerative unit, be careful not to loop
the ground wire.
