Wiring

Follow these steps to install wiring to the terminal blocks:
STEP 1. Terminal blocks for control power require
wires terminated with ring or spade lugs
suitable for use with #10 screws. Refer to
the "Control Power" section on page 8 and
attach the external interface assembly power
connections to terminal strip TB 1.
STEP 2. Connect the wetting voltage return for the
inputs to the terminals labeled Input Wetting
RTN. For SDA-5798 see Figure 8 and for
SDA-5798-1 see Figure 10 on page 12.
Note: The wetting return is the dc-negative
connection or the ac-neutral connection. The
drive current of the input will vary based on
the application voltage shown in Table 1.
