STEP 5. Mounting the core processor

This step is required only for remote core processor with remote transmitter installations (see Figure 6). If you have a 4-wire remote installation, go to Step 6.

Figure 10 shows the remote core processor and mounting bracket. Using the mounting bracket, mount the core processor in a location compatible with the cable length requirements discussed in Step 1.

STEP 6. Connecting input and output wiring

Figure 11 shows the location of the wiring terminals on the Model 3350/3700.

1.Using a flat-head screwdriver, loosen the four captive screws that secure the display cover to the housing.

2.Connect input/output wiring to the appropriate terminals on the gray terminal block. Refer to Table 2 and to the label attached to the back of the display cover (shown in Figure 12).

Use 22 to 16 AWG (0,35 to 1,5 mm2) twisted-pair shielded wire.

Ground the cable shields at a single point only.

If more than two wires must be connected to a single terminal, use a butt splice or spade lug to connect the wires.
