Optional EIB (ACU+ Controller Extended Interface Board)

The optional EIB (ACU+ Controller Extended Interface Board) provides additional
connection points for voltage and current inputs, programmable relay outputs, and
temperature probes. Refer to Figure 4-7.
Procedure
Voltage Inputs, Current Inputs, and Programmable Relay Outputs: Voltage input,
current input, and relay output leads are connected to screw-type terminal blocks located
on the optional EIB (ACU+ Controller Extended Interface Board) mounted inside the
distribution cabinet. Recommended torque for these connections is 5 in-lbs.
