HOW TO INSTALL YOUR AQUA PROBE DIGITAL
DEPTH INSTRUMENT
All Aqua Probe digital depth instruments-the models No.
530, No. 550 and No. 540 remote-can be bracket-
mounted on a surface, such as the top of an instrument
panel, or hanging from the overhead, with the U-shaped
mounting bracket and hardware which is provided.
All Aqua Probe digitals also can be mounted in a panel,
or on a bulkhead, using the adapter flange and bracket
which is also provided with all units.
BRACKET MOUNT
PANEL MOUNTING: To install your Aqua Probe digital
through the face of an instrument panel or bulkhead, you
need a flat area 7" wide by 3 7/8" high for the flange and
unit face. Additionally, you'll need enough clearance
behind the panel or bulkhead for the case of the depth
instrument (3 1/2") plus cable connections.
First, you will need to remove the U-bracket. Then
attach the panel mounting adapter flange to the face of
the depth instrument. using the pan-head machine
screws which are provided. before you attempt to
position the unit in the bulkhead.
MOUNTING LOCATION: You do not have to be
concerned about locating your new Aqua Probe in close
proximity to your compass. There are no magnetic
circuits and there will be no discernible effect on the
compass' performance. However, the unit should be
positioned in such a way that you will have easy access
to the operating controls and switches. Naturally, you
will make sure you have a direct view of the LCD
readout. All hardware necessary for mounting (see list,
page 6) is provided.
WIRING: Aqua probe digital depth units are provided
with a power cord which should be connected to the
ship's power (12V-DC, negative ground) thru a fuse, not
provided. See FUSE paragraph on page six. It then
must be plugged into the power connector on the back of
the unit The RED identified power cord lead is
connected to the POSITIVE (+ ) terminal of the ship's
battery. The BLACK lead is NEGATIVE (-).
POLARITY PROTECTION: Protection against damage
from reverse polarity has been built right into all the
Aqua Probe units. Therefore, should these leads be
reverse-connected in error, the No. 550 and No. 530
depthfinders will NOT OPERATE; they also will not be
damaged.
CAUTION: Since the model No. 540 remote digital
depth instrument is to be used in conjunction with
another main depthfinder, there will be a ground-to-
ground connection between the two instruments
through the jumper cable shield. Therefore, an
erroneously-reversed polarity power connection on
either unit COULD CAUSE DAMAGE to it or the
other. To avoid this: turn on each unit and make
sure
it
is
functioning
properly
BEFORE
INTERCONNECTING THE TWO WITH THE JUMPER
CABLE. Aqua Meter Instrument Corp. cannot be
held responsible for any damage to your depthfinder
due to incorrect installation of your No. 540 remote,
or visa versa.
