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 2:
Check the protection measures
Measures for lightning protection equipotential bond-
ing are used the and the side, e.g. mm² DC: Type 2
V20-C 3PH-1000
5094608
AC: Type 1+2
V50 3+NPE
5093526
No min.
Step 4:
Carrying out the equipotential bonding
Local equipotential bonding must provided the
inverter. lightning
current arrestor (type 1). mm² DC: Type 2
V20-C 3PH-1000
5094608
AC: Type 2
V20 3+NPE
5095223
