Connecting Signals
To connect signals to the DI-148 or DI-158:
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.
3.
Tug gently on the signal lead to ensure that it is firmly secured.
