Emerson 1000 User Manual

The Liebert PSI XR features a rotating display that may be oriented for either tower or rack 

installations.
To set the display for your installation, pull out on the display and rotate it until it is oriented 

correctly, then press it into the UPS until it is seated.

Before connecting input power or connecting the load, Emerson recommends these steps:

• Charge the battery for at least 8 hours.
• Start the UPS on battery to ensure the battery is fully functional and charged. 
• Turn the unit Off and proceed to 3.6 - Connect Input Power and Load.

Connect input power to the UPS, then plug the equipment into the outlets on the rear of the UPS. 

These UPS outlets provide battery backup and surge protection to the equipment when utility power 

fails, spikes or sags (see Figure 10).
