TN line system
A TN line system transfers the PE protective conductor to the installed plant or system using
a cable.
Generally, in a TN line system the neutral point is grounded. There are versions of a TN line
supply with a grounded line the conductor, e.g. with grounded L1.
A TN line system can transfer the neutral conductor N and the PE protective conductor either
separately or combined.
Inverter operated on a TN line system
● Inverter with integrated or external line filter:
– Operation on TN line systems with grounded neutral point permissible.
– Operation on TN line systems with grounded line conductor not permissible.
● Inverter without line filter:
– Operation on all TN line systems ≤ 600 V permissible
– Operation on TN line systems > 600 V and grounded neutral point permissible.
– Operation on TN line systems > 600 V and grounded line conductor not permissible.
