4. Strip back the jacket and insulation of the current loop and serial
cable just enough to connect to the mating terminal block, shown in
Figure 3–6 below. The mating terminal block can be pulled up and
removed from its base to make the cable connection process easier.
5. Connect the 4-20 mA current loop signal wires to the appropriate
terminals, as indicated in Table 3–1 on page 3–14.
6. Connect the serial cable wires to the appropriate terminals according
to Table 3–1 on page 3–14. For reference, Table 3–1 on page 3–14
also shows the corresponding pin numbers for configuring a nine-pin
Sub-D connector for connection to a computer serial port.
7. Re-insert the mating terminal block into its base and verify that each
connection is secure.
8. Strip back the jacket and insulation of the alarm cables just enough
to connect to the alarm relays, shown in Figure 1–6 on page 1–11 or
Figure 1–7 on page 1–12.
