Why You Need a ProSafe Monitor

It is very important that while your vessel is at dock, plugged into shore power, that
it's bonding system be electrically connected to earth. Without this connection the
chance is increased, through accident or failure in the electrical distribution system,
that the bonding system could become electrically “HOT”(presence of 110 or 220VAC).
An occurrence of this type could quickly become deadly both to anyone in the water,
boarding, or even aboard the vessel.

Also of importance to note is the presence of a device called the “Galvanic Isolator”.
This device is installed in the ground wire circuit between shore ground (earth) and
the vessel's bonding system. The purpose of the galvanic isolator is to allow the
bonding system to be isolated electrically from the dock and other vessels at low
voltages (below 1.4 volts) but to keep it connected to the shore ground at high voltage
potentials. This is so the vessel's zincs protect only the vessel they are on. You may
have heard the term “zinc saver”, a term used often to describe a galvanic isolator.

The intent of ABYC A-28 was to create a device which would test for continuity of the
shore power ground wire and to test the integrity of the galvanic isolator. By doing
these two tests at a regular interval you are assured that the vessel's galvanic isolator
is functioning properly and that the shore power system is electrically connected to
the “Shore Ground” (earth).

CAUTION - Because of the presence of deadly high voltages troubleshooting should

be done by a qualified service person only.

“FAIL” indication of the ground wire

WARNING!

DO NOT PERFORM THIS TEST IF THE PROSAFE ONE IS INDICATING A
"REVERSE POLARITY FAIL". INSTALLING THE JUMPER WIRE IN STEP 2
BELOW DURING A REVERSE POLARITY CONDITION WILL PUT HIGH VOLTAGE
ONTO THE BONDING SYSTEM. THIS IS A LIFE THREATENING CONDITION.

1. Be sure the shore power cable is disconnected at the dock post.

2. Using a length of jumper wire (18 ga. or larger) connect one end to the neutral
wire (connection location of the ProSafe One blue wire) and the other end to
the shore ground wire ("AC Shore Ground" stud on the Galvanic Isolator). With
the boat's AC main breaker in the "off" position, reconnect the AC shore cord
to the dock post and turn on the dock post breaker. After the five second test,
the display should show a "NORMAL" condition on the ground wire indicator.
With the display showing a "NORMAL", the problem could be a defective shore
cable, a shore cable connector or faulty ground/neutral connection dockside.

Theory of Operation

The engineers at Professional Mariner have designed the ProSafe One Monitor in
such a way that it connects to your electrical/bonding system for only a very short
amount of time over the period of a day, less then 20 seconds in a 24 hour period.
We have done this because we feel that any type of voltage, AC or DC, left on the
bonding system for extended periods of time can be detrimental to the integrity of
the bonding system’s fittings and struts in contact with seawater.

Each time the vessel is connected to AC shore power, or the ProSafe One Monitor
is activated by the push to test button, or every 3 hours after that, the ProSafe One
Monitor does a series of tests. First it performs a reverse polarity test. Then it performs
the tests required in ABYC A-28: a test of the ground wire continuity and then the
integrity of the Galvanic Isolator. The actual test results are displayed on the remotely
mounted display panel.

In the event you are new at this dock and the ProSafe One has not given you
a "FAIL" indication previously, it has been found that a bad ground/neutral
connection at the dock is a likely occurrence.

If the ProSafe One shows a "FAIL" during this test of the system, the ProSafe
One has failed and needs replacement.

UPON COMPLETION it is imperative that you disconnect the shore cord from
the dock post and then remove the jumper wire. Not removing this jumper is
in violation of ABYC standards.

Installation

Mechanical and electrical installation consists of the following units:

ProSafe One Galvanic Isolator 30 amp or 50/60 amp

[ABYC A28.6.1 - The Galvanic Isolator shall be connected in series with the AC grounding
conductor (green or green w/yellow stripe) in a manner that no other ground conductor
will bypass the isolator back to the shore power ground.]

Professional Mariner would also recommend that you place the galvanic isolator in a dry
location that has ventilation and is as close to the point of cable entry as physically
possible. Using 4 screws, secure the galvanic isolator in a vertical position with the text
on the label right side up, high current studs to the sides. Please note that the electrical
posts are marked “AC Shore Ground” and “Bonding System” and must be connected as
marked or the monitoring of the shore ground wire will not function properly.

Galvanic Isolator Sense Cable

The standard sense cable is 4 meters (13 feet) long. Optional lengths are 1 meter, 7 meters
and 10 meters. The cable is plugged into the control module at one end and the galvanic
isolator at the other end.

ProSafe One Monitor Control Module

The Control Module should be in a location that allows access to the AC mains and within
reach of the display unit cable. Using the diagrams on the following pages, the AC HOT
(brown), NEUTRAL (blue) and GROUND (green/yellow) wires should be connected to shore
power on the inlet side of the main breaker. This location gives the boat owner the ability
to check the integrity of the ground circuit and the Galvanic Isolator before turning on the
main panel breaker supplying power to the vessel. Placing the AC leads on the inlet side
of the main breaker also isolates it from operation while under generator power when it
is not necessary to detect the ground wire continuity. Use the four screws provided to
mount the control module. The control module should be mounted in a dry location and
can be mounted either flat or on a bulkhead.

Trouble Shooting Guide

CAUTION - Because of the presence of deadly high voltages troubleshooting should

be done by a qualified service person only.

If your ProSafe One does not operate, check for AC power and check the blue wire fuse
and the brown wire fuse and make sure they are in good working order.

“FAIL” indication of the reverse polarity

1. Turn off the AC panel "main breaker".

2. Using a volt meter, check the voltage between the green wire and white/blue
wire at the main breaker input side. If the reading is not less than 6 volts (typical)
and is instead close to or over 100 volts, this is an indication of reverse polarity.

3. If there has been no recent electrical work on the boat and/or you have moved
to a different dock, it is probable that the reverse polarity is caused by an improperly
wired electrical outlet in the dock post. This can be tested by checking the voltage
between the ground and neutral slots in the connector of the dock post using the
same process as above.

4. When using dual inlet shore system (ProSafe One dual shore cord part #22080)
it is possible to isolate the mis-wired shore cord by connecting one shore cord
at a time and noting its displayed polarity test results.

It is important to rectify this problem as it is the first of two mistakes that in
conjunction will cause high voltage on the bonding system of the boat.

“FAIL” indication of the Galvanic Isolator

ProSafe One Monitor Remote Display

The display should be mounted in an area that is readily accessible while operating the
AC main breaker or selector switch. The preferred mounting location is next to or within
the main AC breaker panel. The display unit is 2.55” in width by 1.75” in height. It is made
to be flush mounted by drilling a 1 3/8” diameter hole, then slipping the display body into
the hole. Fasten with (2) #4 screws.

1. Be sure the shore power cable is disconnected at the dock post.

2. Check the connection point of the four wire connectors to the Galvanic Isolator.
Look for corroded pins or broken wires. If no problems are found replace the
Galvanic Isolator with a new Galvanic Isolator and retest.

Using The ProSafe One Monitor Continued

Note: With any of the above faults present, and because of the possibility of high AC voltage
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.

To Silence the Audible Alarm:

In the event of a "FAIL" condition, if it is preferred to be able to use your 110/220 volt systems
without the presence of the audible alarm it can be silenced by holding the "TEST" button until
the alarm silences. The alarm will stay silent while leaving the "FAIL" LED illuminated. This does
not rectify the "FAIL" condition, and it is imperative that the reverse polarity condition, ground
wire or isolator be checked for a fault and the fault be repaired.

Maintenance

The ProSafe One Ground Wire and Galvanic Isolator Monitor is self contained and should
need no service. Periodically check all connections are tight, clean and free of moisture.

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.
