Question:

Is it relevant in series connections of VDR+GDT, which component is connected to PE?

See circuit diagram below.

Decision:

The order of VDR and GDT is driven by its specific application, and for safety reasons it

cannot be generally said, which component of the two must be connected to PE. The

PE connection shall be made in accordance with sub-clause 1.5.9.4 and the

corresponding component application requirements of the manufacturer shall be

followed.
