Troubleshooting
AUX/NAC Terminal
The AUX/NAC terminal block is located on the top right corner of the EPS.
Through the ES Panel Programmer, this point can be configured as either a 24 V auxiliary (AUX) power or as a simple reverse polarity Notification
Appliance Circuit (NAC).
Figure 16: AUX/NAC Terminal
Table 2: AUX/NAC Wiring Specification
Voltage rating: 24 V Special Application
Rating: 2A, maximum.
Wiring gauge: 18 AWG (min.)
to 12 AWG (max.).
Wiring notes:
1. All wiring from the AUX/NAC is power limited.
2. Conductors must test free of all grounds and stray voltages before connection to appliances and panel.
3. Terminate Class B NACs as shown using 733- 894. For Canadian applications, mount end-of-line resistor to Simplex-US Model 431537 EOL
plate in accordance with ULC-S527.
4. If circuit is terminated with a 10k EOLR, at the terminals, remove this resistor before wiring.
5. If wiring is routed outside the building, use of a listed secondary protector is required. Use 2081-9028 or 2081-9044. A protector must be
installed at each building exit/entrance. Each 2081-9028 adds 0.2 ohms wiring resistance. 2081-9044 adds 6 ohms wiring resistance, and will
greatly reduce wiring distance.

Note: This Chart indicates the maximum distance for 1/4 -2 A loads. Wiring distance is from the panel terminals to the last appliance. Use of a
2081-9044 protector reduces wiring distance.
