INPUT POWER CORDS
OVER/UNDER VOLTAGE PROTECTION
Should voltage drop below 102V or rise above 132V for more than 8
seconds, power to watercraft is turned off.
SEE TIME DELAY INDICATOR
The green LED indicates power to Watercraft
when illuminated.
TIME DELAY INDICATOR
When unit is plugged in, the red caution LED is
ashing indicating delay. The LCD at the same
will count up to 128 seconds. When the delay
expires, the red caution LED will stop ashing
and power will be applied to the watercraft.
Time delay will also be applied to reset once
power is restored to a safe range following
the 128 second delay. This allows head
pressure to bleed off the A/C Compressor.
SURGE FAILURE
If the red “SURGE” indicator LED is on,
it means that the built-in surge protection
has been sacriced to protect your
equipment and is no longer functioning
properly. Other features will still function,
but the unit is recommended to be replaced.
OUTPUT POWER CORDS
CAUTION LIGHT POLARITY
PROTECTION
Indicates possible miswiring or current to
ground condition present. (Will prevent
power on 50 amp unit only.) The LCD screen
will also indicate REVERSE POLARITY.
3 MODE SURGE PROTECTION
Protects the watercraft's sensitive electronic
systems and appliances from potentially
damaging power surge events without
power interruptions to the watercraft.

Display During Fault Conditions
When the device is powered up, the LCD screen will display "Delay" and
the elapsed time in seconds until it reaches 128 seconds. After the delay
is completed, the unit will go to the normal operating screen showing
voltages and currents as described above. If there is a fault condition
during normal operation such as high or low voltage, the unit will display
that L1 or L2 is high or low; and when power comes back within range
(102V-132V) the unit will begin the delay as described above before
returning to the main screen that shows the voltages and currents.
Reverse Polarity Conditions
If the polarity of the voltages coming into the watercraft is reversed, then
the Surge Guard unit will display the REVERSE POLARITY until this
condition is corrected. Also, current or voltages on ground will
REVERSE POLARITY be displayed as reversed polarity.
TECHNICAL SPECIFICATIONS
1. Plug the Surge Guard* model 67030/67050 into an approved
watercraft receptacle and plug the watercraft power cord into the
Surge Guard unit.
2. Verify the delay indicator is ashing, the LCD is counting. The LCD
will read between 102V and 132V.
3. Once caution light stops ashing (this takes 128 seconds), verify
watercraft power is on.
NOTE: USING WITH POWER CORD ADAPTERS
Purchased power cord adapters will work in most cases with Surge
Guard units but Southwire does not recommend using them for full load
applications due to the possibility of over-heating. Be advised that power
cord adapters have been known to cause res when Amps (electrical
current) ratings are exceeded. Should you decide to use an adapter, our
recommendation is to check on the power cord from time to time to make
sure it is not overheating.

TROUBLESHOOTING
Display for Normal Operation
During normal operation, the device's LCD screen alternates between
two displays, a main screen showing voltages and currents for power
lines 1 and 2 coming into the watercraft; and a secondary screen
showing whether power to the watercraft is ON or OFF, with voltage for
line 1 coming into the watercraft.
The main screen for model 67050 (50Amp) will show the voltages and
currents for lines 1 and 2, whereas model 67030 will only show line 1
since there is no line 2 for that model.
There are two rows or text lines on the LCD screen. The top row for
the main screen shows information for line 1 in the following format:
120V 50A. This means that the voltage on power line 1 coming into
the watercraft is at 120 volts and the watercraft is drawing 50 amps of
current on line 1. The bottom row of the main screen for 67050 shows
voltage and current for line 2.

SYMPTOM CAUSE SOLUTION
Caution light is
ashing
There is a fault.
Read LCD for infor-
mation.
For reverse
polarity or voltage
on ground, move
watercraft to new
electrical source.
LCD reads less than
102V on rst line or
L1, L2 low on either
line.
1. Only partial
power at 50
Amp source.
2. No power at
source
1. Move to a new
source
2. Use inverter
or generator

The top row of the secondary screen for both models shows ON or OFF,
and the bottom row shows the voltage on power Line 1 as L1=120V.
If the power coming into the watercraft is less than 102 volts on either
line 1 or 2, then the main screen will show L1 Low or L2 Low, in place of
the voltage or current. If the power coming in is greater than 132 volts,
then the main screen will show L1 high or L2 high.
