4.7.1 Three-phase 4-wire system (TN, TT, IT system)
The PEM735 can be used in three-phase 4-wire systems, independent of the type of dis-
tribution system (TN, TT, IT system).

(e.g. TN-S system)
1 Connection to the system to be monitored
2
Measuring voltage inputs: The measuring leads should be protected with ap-
propriate back-up fuses.
3 RS-485 bus connection
4 Digital inputs
5 Relay outputs
6
Supply voltage. Power protection by a 6 A fuse, quick response. If being sup-
plied from an
IT system both lines have to be protected by a fuse.
7 Digital outputs (N/O contacts "solid state")
8 Modbus TCP connection
