Installation
CAUTION
Do not install this equipment in hazardous areas other than those indicated
on the approval listing in the “Specifications” section of this manual. Such installation may cause a
safety hazard and consequent injury or property damage.
The SmartSeries ® 751-901 Speaker Amplifier plugs directly into any standard GAI-Tronics 700 Series
enclosure. It also plugs into standard SmartSeries
®
enclosures such as a SmartSeries
®
station RTU
enclosure or an enclosure that houses a party line EOL Module. Use extra care not to damage the
protruding latch wings of connector J2 located on the bottom edge of the amplifier during installation.
When installing the assembly in one of these enclosures, you must also connect the 10-conductor keyed
ribbon cable to J2 on the bottom of the Speaker Amp/Power Supply PCBA. Be sure that the red line on
the edge of the cable lines up with J2-pin 1.
Ensure that the connectors mate securely and then tighten the four screws in the corners of the front panel.
