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 grounding conductor made of copper wire with a cross-section of at least
10 mm² to the connecting terminal plate for the AC cable.
• Connect additional grounding with the same cross-section as the connected grounding
conductor to the connecting terminal plate for the AC cable (see Section 6.3.3, page 27
). This prevents touch current if the grounding conductor at the connecting terminal plate
for the AC cable fails.
Connection of additional grounding
In some countries, additional grounding is generally required. In each case, observe the
locally applicable regulations.
