Position and identify the disconnect device so as to provide
safe and easy operation.
Label the disconnect device as being for the Mag Meter.

AC Power Wiring
For AC power use three wire, sheathed, cable with cable
diameter of 18 AWG (not supplied).
AC wire insulation temperature class must not exceed the
maximum ambient temperature of its location (typical, 185°F,
85°C).
Use conduit and conduit fittings (not supplied) that are rated
for Zone 2 hazardous locations. To maintain a IP66 rating,
use watertight fittings that are rated IP66 or better.
To prevent accidents connect main power only after all
other wiring has been completed.
The amplifier 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 filtering or isolation
system may be required.
AC wiring is the same for meter mount and remote mount
amplifiers.

any device maintenance.
To re-position or rotate the display/control card in the
amplifier:
1. Remove display chamber cover. Turn the cover
counterclockwise to remove it from the amplifier. If
necessary, use a strap wrench.
2. Remove the 2 card screws and washers. (NOTE: Use a
split screwdriver to prevent dropping screw into
3. Tilt card up/out approximately 45 degrees at the holding
clips.
4. Gently pull card down and out from between holding clips.
