relays are normally open.

Input1: This is a general purpose input. The factory configuration for this input is to detect a
failure in the AC main signaled by a UPS device.

referred to as “AUX” which provides access to the device local console for configuration and
monitoring purposes. In order to use this, you must connect to the “AUX” port to an asynchronous
terminal (or to a PC with terminal emulation).
