7.5Setup System - Setup Zones

The Liebert AC4 has two zones that may be used to define different areas—rooms or sections of a room. The Liebert AC4 effectively performs as two separate units, controlling each zone separately, for examply, using a different rotation sequence for devices in each zone.

Each zone may have two to four outputs associated with it. By default, Zone 1 has four associated outputs and Zone 2 has none.

To set up zones:

Log In and Choose Setup System

•From the Main Menu, use the arrows ↑↓ to choose System and Control, then press Enter ↵ (see 7.1 Login for help).

•Enter your password at the Login screen.

•From the System and Control Menu, use the arrows ↑↓ to choose Setup System, then press Enter ↵.

Select Setup Zones

•From the Setup System Menu, shown at right, use the arrows ↑↓ to choose Setup Zones and press Enter ↵.

7.5.1Set Up a Zone

•From the Setup Zones Menu, choose a zone—for example, Zone 1—and press Enter ↵.

•On the Number of Devices screen, Use the arrows ↑↓ to select the number of outputs for this zone, then press Enter ↵. The example at right shows four outputs in Zone 1.

Table 15 shows the default number of outputs for each zone.
