Step 3. Using figure 3.19, locate the two No. 10 studs provided on

the Remote I/O Head for grounding purposes. The

Remote I/O Head must be properly grounded to minimize

personnel hazard and to ensure proper operation. The

ground path, when using a 1KVA transformer, should have

less than 10 milliohms resistance. The grounding wire

must be a minimum size of 14 AWG. The insulation should

be green for U.S.A. applications.
