3.3.1 Terminal
Connections
All wire connections are made through the base entries to the terminal block (Figure 19).
The terminal block accepts 14 AWG to 22 AWG (2.1 to 0.3 mm
2
) stranded or solid core
wire. Each wire should be stripped to .25 in (.64 cm). To connect the wire to the terminal
block, insert the conductor into the connection space as shown in Figure 19 and tighten
the corresponding screw terminal. There are twenty terminal connections. The following
pages contain descriptions and specifications for each connection.
WARNING:
Relay contacts must be protected against transient and over-voltage
conditions (Figure 20).

These connections are for the SPDT ALARM relay. The ALARM output is time delayed
for 2, 4, 8 or 10 seconds. This time delay can be set by Modbus, HART, or by Dipswitch.
The ALARM output can be normally energized or normally de-energized, latching or
non-latching, and these options are also set via can be set by Modbus, HART, or by
Dipswitch (Section 4.4). For all relay connections see Figure 20.
