Automatic Operation; Manual Operation; Ground Wire Red; Galvanic Isolator Red - Regal 3760 Owner's Manual

The monitor and the galvanic isolator are located behind
the AC/DC panels. Never try to access these parts with
the shore power cords connected. Remove the shore
power cords from the receptacles.
OPERATION
NOTICE
IN THE EVENT OF AN INDICATION
OF REVERSE POLARITY, AN ISOLATOR
FAILURE, OR GROUND WIRE FAILURE,
DISCONNECT THE AC SHORE POWER
CORD IMMEDIATELY!

Automatic Operation

Be sure the main AC panel breaker is in the "off" posi-
tion. Attach both ends of the vessel shore power cord,
one end to the dockside receptacle and the other to the
shore power inlet receptacle.
Turn on the dockside breaker. The presence of AC on
the inside side of the main breaker panel will activate the
monitor. After the monitor cycles through its self-test it
will display a condition of polarity, the shore ground wire,
and condition of the galvanic isolator. The test sequence
takes about 20 seconds. The monitor will repeat this test
automatically every 3 hours.
A "FAIL" indication on the remote display of either the
ground wire or the galvanic isolator is an indication of an
ungrounded bonding system and should be considered a
very dangerous situation. Because of the possibility of
high AC voltages on the bonding system it is highly rec-
ommended that the vessel's shore power cord be
diconnected until a professional can determine and re-
pair the fault.

Manual Operation

To operate the monitor manually press the "TEST" but-
ton on the display panel, wait for the test to complete
(about 5 seconds) and read the displayed test results.
Equipment Operation
What The Tests Results Mean
The display consists of 6 LED's , three green and three
red. The three green LED's should be lit to show proper
polarity, good ground wire continuity, and a functioning
galvanic isolator.
A reverse polarity red LED indicates that the line and
neutral wires are reversed. Unless you have had recent
electrical work done on your shore power system, this is
typically a fault of the dockside receptacle. This needs to
be corrected as it enhances the chance of accidently hav-
ing 120 volts AC on the vessel's grounding system.
Note: Because of how the ground wire testing is done, a
reverse polarity hook-up will also show a "FAIL" to the
ground wire. By rectifying the reverse polarity, the ground
wire problem will most likey not be an issue.

Ground Wire Red

Indicates that the ground wire (green wire) is not con-
nected to the shore correctly. The fault can be caused by
the green wire being open or disconnected, by a bad con-
nection at the galvanic isolator, shore power cord plug,
dockside plug or even the metal tip of the plug itself not
making good contact. It can also be caused by the ground
wire not being connected to the neutral back on the
dockside receptacle.

Galvanic Isolator Red

Indicates a failure of the galvanic isolator. The galvanic
isolator can fail as a short or an open circuit. A short will
no longer isolate the boat in a low DC manner and will
increase erosion of your zincs. An open circuit eliminates
AC ground protection to your bonding system which could
be life threatening. If the galvanic isolator shows a "FAIL"
it should be replaced immediately.
