The SeQual eQuinox can be powered with AC or DC supply or with an external battery. The battery can be charged while using either AC or DC power, and it continuously charges while plugged in. The eQuinox also automatically changes to battery power when the unit is disconnected from an AC or DC power supply.
To begin charging the unit, plug the AC power supply cord into the recessed external connector. Plug the other end of the cable into the recessed connector on the side of the Sequal eQuinox unit. Then plug the connector into an AC outlet. A green indicator on the power supply and the external power indicator on the control panel will light up.
