Grounding Circuit
It is recommended that you ground each cabinet and console type HIS separately. If separate
grounding is not feasible, refer to “Grounding Grouped Cabinets” or “Grounding side-by-side
Cabinets.” When providing lightning arresters on power and signal lines, those arresters need to
be grounded to the same bus. For details, see Section 1.5, “Noise Countermeasures.”
Separate Grounding
Each cabinet should be grounded as shown below:
Grounding with a ground resistance of 100 ohms or less and a grounding bus of 22 mm
2
or
thicker.
