CHAPTER2
NOTE:
For best performance, the AC cable
voltage drop should not exceed 10 volts, or
10 percent at 115 volts and 5 percent at 230 volts.
Make sure that even with the AC voltage drop, the
AC voltage always stays in the operating windows.
The minimum electrical service amperage required by
an MJF-212A system is the sum of each loudspeaker's
maximum long-term continuous current. An additional 30
percent above the minimum amperage is recommended to
prevent peak voltage drops at the service entry.
ElECTRICAl SAfETy ISSUES
Pay close attention to these important electrical and safety
issues.
CAUTION:
In the unlikely event that the
circuit breakers on the monitor's user panel
trip (the white center buttons pop out), disconnect
the AC power cable. Do not reset the breakers with
the AC connected. Contact Meyer Sound for repair
information.
CAUTION:
The MJF-212A monitor requires
a grounded connection. Always use a
grounded outlet and plug.
CAUTION:
Do not use a ground-lifting
adapter or cut the AC cable ground pin.
8
CAUTION:
Do not exceed the current
capability of the monitor's 20-amp AC
connector. When looping, always take into account
the current draw of all loudspeakers on the circuit,
including the first unit.
CAUTION:
Make sure that the power plug
is appropriate for the AC power at the site
where you will operate the MJF-212A monitor. In
addition, the connector must be rated for the total
load of all MJF-212A loudspeakers looped to the
same power plug.
