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.
