2.3. System
Grounding
The 19" cabinet is grounded by the power cable through the ground pin of the mains
connector (= protective earth). In order to avoid ground loops the internal ground is isolated
from the protective earth. The internal ground is used on the BNC connectors or GROUND
plugs of the modules that are inserted into the EPMS-07 housing. The internal ground and
mains ground (= protective earth) can be connected by a wire using the ground plugs on the
rear panel of the instrument. It is not possible to predict whether measurements will be less or
more noisy with the internal ground and mains ground connected. We recommend that you
try both arrangements to determine the best configuration.
