1.6 Typical Configuration
Figure 1.3 on the next page shows an example of external devices connected to the Liebert AC8
controller board. Up to eight devices may be connected to the eight digital inputs and eight digital
outputs. There may be up to four analog sensors connected to the analog inputs, and up to two devices
connected to the control relay outputs. The EPOP connection allows for one device, possibly a UPS or
generator input actuated during a power failure.
Remote access is available via Liebert SiteScan Web™ and through the modem, which enables pager
notifications and use of the Service Terminal Interface. A computer may be connected to the RS232 port,
providing access to the features of the Service Terminal Interface.
