System Grounding
The 19" cabinet is grounded by the power cable through the ground pin of the mains
connector (= protective earth, see chapter 1). 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.
