2.0INSTALLATION

2.1Installation 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.

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.

2.1.1Unpacking 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:
