Installation
Warning
It is not possible within the scope of these
instructions to fully acquaint the installer
with all the knowledge of electrical systems
that may be necessary to correctly install
this product. If the installer is not
knowledgeable in electrical systems we
recommend that an electrical professional
be retained to make the installation.
1. Disconnect all AC and DC power
Disconnect all AC power originating on or
off the vessel. This includes inverters,
generators, shore power attachments and
any other device capable of supplying AC
power to the ship’s circuits. Disconnect the
main positive DC cable from all batteries to
eliminate the possibility of a short circuit
and to disable the inverter while installing
the meter.

2. Select mounting location and cut opening
Select a mounting location which is protected from water on the meter front and back and is not
in an area where fl ammable vapors from propane, gasoline or lead acid batteries accumulate.
The meter is not ignition protected and may ignite such vapors. There are two mounting
methods for the meters, surface mount or panel mount.
Surface Mount: Drill fi ve clearance holes as shown below. The part number of the meter will
determine the size and location of the clearance holes. Use the nuts and washers supplied in the
accessory package to secure the four mounting studs to the mounting surface. This method will
work on mounting surfaces up to 5/8” thick.
PN 8244 / PN 8245
Micro Meters
Panel Mount: For thicker mounting surfaces, the meter can be mounted into a 0.125” thick
panel. Blue Sea Systems offers meter mounting panels for our standard size meters only. Use
PN 8013 to mount a single meter or PN 8014 to mount two meters.

3. Installation of Voltmeter Wires: Wire the meter as shown below, making certain to attach
the hot lead to the terminal on the meter marked “+” and the neutral lead to the terminal marked
“-”. Use a minimum 16 AWG wire, black for hot and white for neutral. Verify that the circuit
protection device (circuit breaker or fuse) protecting the circuit to be monitored will also protect
the 16 AWG meter sensing wires. If it is oversized, install a 1 ampere fuse in the hot lead near
the source. Do not connect the voltmeter in a serial (in-line) confi guration.

4. Calibration
The voltmeter is calibrated at the factory and recalibration should never be necessary. However,
if adjustment does become necessary the needle may be reset to the zero mark.
In the center of the black area on the meter front is an adjustment screw. This screw activates a
small cam that defl ects the meter needle slightly to adjust the needle position.
Using a small screw driver, turn the screw no more than 90 degrees right or left, as necessary.
DO NOT ROTATE THE ADJUSTMENT SCREW THROUGH 360 DEGREES.
