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.
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.

“FAIL” indication of the Galvanic Isolator
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.
Tr o u b l e S h o o t i n g
“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.
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.
