To prevent accidents connect main power only after all
other wiring has been completed.
The amplifi er is a microprocessor device. It is important
that the power supply be as “clean” as possible. Avoid
using power lines that feed heavy loads; pumps, motors,
etc. If dedicated lines are not available, a fi ltering or
isolation system may be required.
Power wiring is the same for meter mount and remote mount
amplifi ers.
1. Remove the Wire Port cover from amplifi er connections
chamber.
2. Lay out power cable and conduit to amplifi er.
3. Place cable in conduit.
4. Strip cable back 2 inches (50mm).
5. Strip wires back ¼ inch (6mm).

Adjustable Display/Control Card
Because meter positioning sometimes places the amplifi er
display/programming chamber in an awkward position, the
display/control card is adjustable in 90-degree increments.
Disconnect main power to the unit before attempting any
device maintenance.
To re-position or rotate the display/control card in the amplifi er:
1. Remove display chamber cover. Turn the cover
counterclockwise to remove it from the amplifi er. If
necessary, use a strap wrench.
2. Remove the 2 card screws and washers. (NOTE:
Use a split screwdriver to prevent dropping screw into
enclosure.)
3. Tilt card up/out approximately 45 degrees at the holding
clips.
4. Gently pull card down and out from between holding clips.
5. Rotate card to appropriate position.
