conductor connected and disconnects the inverter from the utility grid if this is
the case. Depending on the installation site and grid configuration, it may be
advisable to deactivate the grounding conductor monitoring. This is necessary,
for example, in an IT system if there is no neutral conductor present and you
intend to install the inverter between two line conductors. If you are uncertain
about this, contact your grid operator or AISWEI.
5.4.2 AC terminal connection
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.
Risk of injury due to electric shock and fire caused by high leakage
current
• The inverter must be reliably grounded in order to protect property and
personal safety.
• The PE wire should longer 2 mm than L,N during strip the outer sheath
of AC cable.
