2.1Installation Considerations

The Liebert AC4 must be installed indoors and may be mounted on the surface of a wall or flush- mounted, depending on the user’s application, the location of equipment to be connected and the type of wall the unit will be mounted on.

The Liebert AC4 should be mounted where it can be easily accessed. On-site personnel would access the unit through the LCD on its front cover or the service terminal connected to the RS232 port.

In addition to the communications connections, the site also must have electrical service and must permit connecting the unit’s four digital inputs and four digital outputs.

The wall material must be capable of supporting the weight of the Liebert AC4: see 8.0 Specifications.
