Model M-2000 Mag Meter
Power Connections
External Disconnect
Install an external disconnect switch or circuit breaker that meets local standards.
Position the M-2000 in an accessible location.
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 the AC power connections, use three wire-sheathed cable with an overall cable diameter of 0.2 inch to 0.45 inch (5 mm
to 12 mm). For signal output, use 18 to 22 gauge (0.25 mm
2
to 0.75mm
2
) shielded wire. Overall cable diameter between 0.12
inch and 0.35 inch (3 mm to 9 mm).
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.
Power wiring is the same for meter mount and remote mount amplifiers.
Remote Mount Installation
If you are installing the M-2000 amplifier in a remote location, review the procedures in this section.
Mount Bracket to Amplifier
1.
Align bracket-mounting holes with amplifier mounting holes.
2.
Attach bracket to amplifier with supplied screws. Torque screws to 80 inch pounds.
Wiring Configuration
Wiring between the detector and the M-2000 amplifier comes complete from the factory. If your installation requires the use
of conduit, we recommend that you follow these steps when wiring the detector to the amplifier.
1.
Remove the junction box lid. Carefully remove the wires connected to the terminal blocks that run to the M-2000
amplifier. See the chart below for a reference of wire color to terminal connection.
2.
Run cable through the conduit from the amplifier location while retaining the wiring of the cable to the amplifier, as
supplied.
3.
Complete conduit assembly on both ends and rewire the cable into the junction box as it was
previously wired.
