the rubber feet can provide stability when the unit is placed on a flat surface or
stacked.
Hardware Hookup
Refer to the following hookup diagrams for the appropriate AMP3x80 model and,
aside from attaching power last, complete the connections in any order. Refer to
“Network Wiring” on page 8 when making network connections.
WARNING: To prevent injury and / or equipment damage due to electric shock,
disconnect power from the AMP3x80 prior to making any wiring connections.
NOTE: Use only the supplied power cord, or equivalent, to connect to the AC
power source.
NOTE: To prevent overheating, do not operate this product in an area that exceeds
the environmental temperature range listed in the table of specifications.
Consideration must be given if installed in a closed or multi-unit rack assembly since
the operating ambient temperature of the rack environment may be greater than the
room ambient. Contact with thermal insulating materials should be avoided on all
sides of the unit.
NOTE: The maximum continuous current from equipment under any external load
conditions shall not exceed a current limit that is suitable for the minimum wire
gauge used in interconnecting cables. The ratings on the connecting unit's supply
input should be considered to prevent overloading the wiring.
