Card Connections and Installation
WARNING
The following connection informa-
tion is intended to be used by quali-
fied service personnel. Failure to
recognize and observe standard
safety precautions could result in
personal injury or death.
3.3.1 Screw terminal connector card
The screw terminal connector card is shown in Figure
3-1. Connections are made directly to the screw termi-
nals of the 20-terminal blocks. One terminal block is
dedicated to each of the 20 channels. Each screw termi-
nal will accommodate #16-22 AWG wire.
Wiring procedure
Perform the following procedure to wire circuitry to
the screw terminal connector card:
WARNING
Make sure all power is off and any
stored energy in external circuitry is
discharged.
1. If mated together, separate the connector card from
the relay card by removing the mounting screw
and pulling the two cards away from each other.
Remember to only handle the cards by the edges
and shields to avoid contamination.
2. Using an insulated screwdriver, connect the
circuitry to the appropriate terminals. Figure 3-2
shows how connections would be made to deliver
power to a DUT (device under test) using Channel
2.
3. Referring to Figure 3-3, remove the top half of the
cable clamp as follows:
a. Loosen the cable clamp screw enough to disen-
gage it from the bottom half of the cable clamp.
b. Using your thumb and forefinger, press the
retaining clips inward and, with your other
hand, remove the top half of the clamp.
