3.2.2.2 NACs (1-4) Configured as Auxiliary Circuits
When NAC 1 and NAC2 are configured for auxiliary output through the configuration
tool, the outputs are always on, unless the software is programmed for special pur-
poses. Refer to the configuration tool Zeus manual for specifics when configuring
the NACs for auxiliary output. These circuits are Power Limited.
