Functional Description

J1--20, 22 1 15 Vac Power Output: [J1--20 (H), J1--22 (C)]

These power output pins provide the 115 Vac operating power for the data loader.

The 115 Vac (H) and 115 Vac (C) interconnect wires should be shielded or twisted and

shielded with an insulating jacket over the shield. The shield should be connected to

chassis ground (J1--21).
