4 Terminal Assignment
The electrical connections are made via screw-clamps. The numbering can be found on the front side
of the clamps. The maximum wire cross section is 2,5 mm². The EMC-installation instruction is to be
complied with. Maximum interference immunity is achieved by direct connection of the cable screen
with “clean” and low resistance protective ground (PG). A lengthening of the cable screen makes the
interference immunity considerably worse. The connection of the screen should be done directly with a
cable clamp.
If, however, a connection to a PG is not possible, the cable screen may be connected to clamp 15 of the
amplifier (analogue ground/screen). Anyhow, enough interference immunity is to be ensured.

Terminals “supply ground” and “analogue ground” are isolated galvanically. To unset this isolation
clamp 3 and 4 are to be bridged.
