Wiring Differential Inputs
ATTENTION: To comply with UL restrictions, this equipment must be powered
from a source compliant with Class 2 or Limited Voltage/Current.
Be careful when stripping wires. Wire fragments that fall into a module could
cause damage at power up. Once wiring is complete, make sure that the module
is free of all metal fragments.
IMPORTANT 1769-IF4I input channels connected to current sources must have a jumper wire
placed between Ch#_iRtn and the Ch#- terminals for that channel.
