Ground Connection
The ground connection should be made using
the same gauge wire as the power connection.
It is common for the alternator to be grounded
through its chassis. If the alternator is not
grounded through its chassis and instead employs
a small (10 AWG - 6 AWG) wire to connect to
ground, this wire should also be upgraded to 4
AWG when installing amplifier systems with main
fuse ratings above 60A.
Many vessels employ small (10 AWG - 6 AWG)
wire to ground the battery to the vessel ground
point and to connect the alternator’s positive
connection to the battery. To prevent voltage
drops, these wires should be upgraded to 4
AWG pure copper wire when installing amplifier
systems with main fuse ratings above 60A.
Turn-On Wire
The MHD900/5-24V uses a conventional +12V
or +24V remote turn-on wire, typically controlled
by the source unit’s remote turn-on output. The
amplifier will turn on when +12V or +24V is
present at its Remoteinput and turn off when
+12V or +24V is switched off. If a source unit
does not have a dedicated remote turn-on output,
the amplifier’s turn-on lead can be connected
to +12V via a switch that derives power from an
ignition-switched circuit.
The MDH900/5-24V’s Remote turn-on
connector is designed to accept 18 AWG – 12
AWG wire. 18 AWG is more than adequate for
this purpose. To connect the remote turn-on wire
to the amplifier, first back out the set screw on the
bottom of the Power Connector Plug, using the
supplied hex wrench. Strip 1/2 inch (12mm) of
wire and insert the bare wire into the receptacle,
seating it firmly so that no bare wire is exposed.
When using smaller wire, it may be necessary to
strip 1 inch of insulation from the wire and fold
the bare wire in half prior to insertion. While
holding the wire in the terminal, tighten the
set screw firmly using the supplied 2.5 mm hex
wrench, taking care not to strip the head of the
screw and making sure that the wire is firmly
gripped by the set screw.
Amplifier Power Connector Plug
To connect the power wires and the remote
turn-on wire to the amplifier, unplug the power
connector plug from the amplifier chassis (pull
back firmly) and back out the set screws on
the connector plug, using the supplied 4 mm
hex wrench for the +24 VDC and Ground
connections and the supplied 2.5 mm hex wrench
for the Remoteconnection. Strip 3/8 inch (10
mm) of insulation from the end of each wire and
insert the bare wire into the receptacle on power
connector plug, seating it firmly so that no bare
wire is exposed. While holding each wire in place,
tighten each set screw firmly, taking care not to
strip the head of the screw.
Never make power connections with a “live”
wire. Always disconnect the negative battery
post before making any connections or
adjustments to a 24V power connection!
