supply input allows for the connection of AC power to the port between the range of 100 – 240
VAC and 50 – 60 Hz. Power consumption for the unit is 1.0A (OMS11) only. An external chassis
ground post is located on the OMS11. The ground post is a #10-32 threaded stud that is used for
external grounding and should not be used to ground the AC power Source on J6 and J10. The
mating power connector is a 4-pin socket MFG P/N (D38999/24FC4SN) connecter. The mating
