Four steps comprehensive protection systems
Step 1:
Check the separation distance
If the required separation distance cannot com-
plied with, then the metallic parts must intercon-
nected able carry lightning current.
Step 4:
Carrying out the equipotential bonding
Local equipotential bonding must provided the
inverter.
