6.4.2 Grid connection
Procedure:
1.
Switch off the miniature circuit-breaker and secure it
against being inadvertently switched back on.
Safety in accordance with IEC 62109 when the grounding
conductor monitoring is deactivated.
In order to guarantee safety in accordance with IEC 62109
when the grounding conductor monitoring is deactivated,
carry out one of the following measures:
• Connect a copper
-wire grounding conductor with a cross-
section of at least 10 mm² to the AC connector bush insert.
• Connect an additional grounding that has at least
the same
cross-section as the connected grounding conductor to the
AC connector bush insert. This prevents touch current in the
event of the grounding conductor on the AC connector bush
insert failing.
Danger to life due to high voltages in the inverter
Touching the live components can lead to lethal electric
shocks.
•
Before performing the electrical connection, ensure that the
AC circuit-breaker is switched off and cannot be
reactivated.
