Connecting The Second Protective Conductor; Connecting The Battery - Growatt MIN 2500TL-XA Installation & Operation Manual

6.3 Connecting the second protective conductor

In some installation countries, a second protective conductor is required to prevent a
touch current in the event of a malfunction in the original protective conductor.For
installation countries falling within the scope of validity of the IEC standard 62109, you
must install the protective conductor on the AC terminal with a conductor cross-section
of at least 10 mm²Cu.Or Install a second protective conductor on the earth terminal with
the same cross-section as the original protective conductor on the AC terminal. This
prevents touch current if the original protective conductor fails.
