Typical Hookup for Single 50 Amp/220-250 Volt Inlet
Using The ProSafe One Monitor
Note: In the event of an indication of a reverse polarity, an isolator failure or groundwire failure,
disconnect the AC shore cord immediately (see troubleshooting guide)
Automatic Operation:
Be sure your main AC panel breaker is in the off position. Also be sure your dock post AC breaker
is in the off position. Attach both ends of the vessel shore cord, one end to the dock post
receptacle, the other to the power inlet on your vessel. Turn on the dock post breaker. The
presence of AC on the input side of the main panel breaker will activate the ProSafe One Monitor.
After the ProSafe Monitor cycles through its self test, it will display the condition of polarity, the
shore ground wire and of the Galvanic Isolator. The test sequence takes about 20 seconds. The
ProSafe One 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 recommended that
the vessel’s shore cord be disconnected until a marine technician can determine and
repair the fault.
Manual Operation:
To operate the ProSafe One Monitor manually simply press the “TEST” button on the display
panel, wait for the test to complete (about 5 seconds) and read the displayed test results.
Interpretation of Test Results:
The display consists of six LEDs, three green and three red. The three green LEDs 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 AC electrical system or shore cords, this is typically a
fault of the receptacle which your shore cord is plugged into. This needs to be corrected as it
enhances the chance of accidentally having 110VAC (220 VAC in Europe) on the vessels bonding
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
likely be rectified.
Ground Wire RED:
Indicates that the ground wire (green wire) is not connected to the shore properly. The fault can
be caused by the green wire being open or disconnected, by a bad connection at the galvanic
isolator, shore cord plug, dock 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 dock {a requirement under the N.E.C. (National Electrical Code)}
Galvanic Isolator RED:
Indicates that there has been a failure of the galvanic isolator. The galvanic isolator can fail as
a short or an open circuit. A short it will no longer isolate the boat in a low level DC manner and
will increase erosion of your zincs. An open circuit eliminates AC ground protection to your
bonding system. Both situations are cause for concern, the later being a life threatening situation.
If the galvanic isolator shows a "FAIL", it should be replaced without hesitation due to this danger.
