Note: This chart indicates the maximum distance for 1/4 -2A loads. The wiring distance is from the panel terminals to the last appliance.
Use of a 2081-9044 protector reduces wiring distance.
Output of AUX or NAC is 24 V nominal. The minimum voltage is 19.5 at minimum battery; the maximum is 29.5 V. Aux Loads include the
4090 series of IDNet ZAMs and IAMs, and any listed device operating within the output limits of the AUX. Calculate the wiring loss for the
actual devices used. Compatible appliances include the 4009 NAC extenders, used in reverse-polarity activation mode.
