Figure C3 illustrates an automation control cir-
cuit connected to the low side of one of the Iso-
lated Automation Inputs. Even though the switch
drives an OptoIsolator, it is still connected to
DPC ground and not isolated. The SH707 jumper
block is in the factory default postion (JU724).
Any of the examples in Figure C2 can be used
in place of the block labeled
