Connecting Digital Input Signal Leads
Connect signal leads to the DI-4730 digital inputs:
1. Insert the stripped end of a signal lead into the desired terminal directly under the screw.
2. Tighten the pressure flap by rotating the screw clockwise with a small screwdriver. Make sure that the pressure
flap tightens only against the signal wire and not the wire insulation. Do not over-tighten.
This ground lug should always be connected to a solid chassis or earth ground. This connection is man-
datory when connecting signal leads.
