2.0 INSTALLATION
2.1 Installation Considerations
The 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 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 AC4: see 8.0 - Specifications.
2.1.1 Unpacking and Preliminary Inspection
• Before unpacking the AC4, inspect the shipping carton for damage or signs of mishandling, such
as gashes or holes in the carton or severely flattened corners.
• Open the shipping crates carefully. Use care to avoid puncturing the container with sharp objects
that might damage the contents.
• Inspect the AC4 and all included components for damage.
• If any damage from shipping or mishandling is observed, immediately file a damage claim with
the shipping agency and forward a copy to:
Liebert Corporation
1050 Dearborn Drive
P.O. Box 29186
