Optional Alarm/Control Connections (to Primary Module only)
Alarm/control connections are made to the ACU+ Controller Customer Interface Board (IB2). The IB2
board provides connection points for digital inputs and relay outputs. System required connections
are factory wired to the IB2 board. The customer may wire to un-used digital input and relay outputs,
if desired. The IB2 board is located in an enclosure above the ACU+ Controller (see Figure 10 or
Figure 11). To access these connections, loosen the captive fastener on the front of the enclosure and
slide the IB2 board partially out of the shelf. Note that a wireway is provided to route the wires to the
IB2 board, as shown in Figure 10 or Figure 11. Connect external alarm/control wiring to terminal
blocks J3-J9 of the IB2 board, as required. Refer to Figure 17.

Digital Input Connections
Up to eight (8) digital inputs may be connected to the IB2 board. Digital inputs that have factory
connections are listed in Table 3. A blank column in Table 3 is also provided if you want to document
custom connections to un-used digital inputs.

• Observe proper polarity per Table 3. Note that you must supply both paths for the digital input
(either a positive or negative signal and the opposite polarity return path).
• The digital inputs can be configured to provide an alarm when the signal is applied (HIGH) or
removed (LOW) (Local menu "Settings / System Dashboard / General"). Refer to Appendix A in
the NetSure ITM Operation Manual (Section 6047).

• Connect a 22 AWG lead from the circuit breaker alarm connector located on the last PDU to the
(-) input of one of the unused digital inputs on the IB2 board. Connect a second 22 AWG lead from
the NetSure ITM System Ground/Return (+) to the (+) input of the same digital input on the IB2
