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.

WARNING

Do not disconnect equipment while circuit is energized.

The SmartSeries

751-905 Speaker Amplifier plugs directly into any standard GAI-Tronics Page/Party

Series enclosure. Use extra care not to damage the protruding latch wings of connector J2 located on the

bottom edge of the amplifier during installation. It also plugs into standard SmartSeries

as a SmartSeries

station RTU enclosure or an enclosure that houses a party line EOL Module.

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.

For continued IP 66 protection, torque setting for securing the amplifier into the enclosure should be 10 to

12 in-lbs. or 1.13 to 1.36 n-m.
