* Note: Whenever they are not used, the measurement probes must be terminated with
the (golden) SMA terminations.
4.2.4. Grounding (Earthing)
Grounding must be carried out. Connect an earth-bonding cable to the grounding bolt
inside the PSR. To get access to the grounding bolt, the front door must be opened by
unlocking both locks at the left side of the cabinet with the supplied key.
The PSR is designed to operate under AC (89-264 VAC), DC (-62 to -34 VDC) / max
load 160W. A Ground wire needs to be connected correctly without removing or
changing the Ground lug of the supply conductors:
