2 INSTALLATION
This section provides instructions for installing, mounting and connecting power to the Liebert AC8.
2.1 Installation Considerations
The Liebert AC8 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 and sensors to be monitored and the type
of wall the unit will be mounted on.
The Liebert AC8 should be mounted where it can be easily accessed. On-site personnel would access the
unit through the LCD on its front cover, service terminal connected to the RS232 port or through Liebert
SiteScan™. For off-site monitoring, the Liebert AC8 should be placed near communications means such as
a telephone line connection that would permit remote access.
In addition to the communications connections, the site also must have electrical service and must permit
connecting the unit’s eight digital inputs, eight digital outputs and four analog inputs.
The wall material must be capable of supporting the weight of the Liebert AC8: see Specifications on
page107.
NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in which case
the user will be required to correct the interference at his own expense.
