Installation
Making connections to the CRA
The CRA connections are made to terminal board TB1,
located on the top of the back-panel; see Figure 2. A color-
coded wiring decal clearly identifies connections; see Figure
1.
Connecting the leads to the terminal board requires using
the tool supplied with the CRA assembly or an acceptable
substitute; see Figure 4.
To use the tool, place it in the square hole next to the round
hole where a wire is to be connected. Push the tool firmly
into the hole to release the connector. Place the bare wire
of the lead into the round hole, remove the tool from the
square hole, and check the wire to make sure it is properly
placed and is tight in the terminal board. Refer to Figure 5
for placement of the tool and the wire in the terminal board.
