With installations using multiple batteries, the inverter can be operated from one of the
vehicle or vessels’ 12 volt batteries, so there’s always one battery with adequate
charge to start an engine.
Other

features include a high-surge capability (up to 6000
watts), which is required to start heavy loads such as motors and other inductive
devices.
1.3 Warnings, Cautions and Notes:
It is very important that any operator/installer of the inverter read and follow the
installation and operation instructions included in this manual. In particular, close
attention should be paid to the WARNINGS (possibility of serious injury or death),
CAUTIONS (possibility of damage to the inverter and/or other equipment), and
NOTES (included to assist you in achieving the maximum utility and the longest
working life from this advanced-design inverter).
WARNING ABOUT AC OUTPUT
The
MAXX
SST
™
3000
is an industrial grade, heavy-duty device that produces
voltages similar to commercial AC power. There are special precautions that must
be taken when you are working with this inverter output. First, Hot and Neutral ter-
minals are both powered with respect to ground. Consider this output as a three-
wire system and NEVER assume that all circuit wires are unpowered because a
front-panel breaker trips. A breaker trips only because the Neutral to Hot load is
greater than 15 amps. The NEUTRAL IS STILL POWERED WHEN A FRONT-PANEL
BREAKER TRIPS. Second, NEVER connect ANY Neutral terminal or wire to ground.
This shorts the output and the inverter will shut down.
The inverter has independent front panel circuit breakers located directly below the
outlet circuits they protect. IF ONLY ONE FRONT-PANEL BREAKER TRIPS,
ALL OTHER OUTPUTS ARE STILL POWERED, INCLUDING THE HIGH OUTPUT
TERMINAL CIRCUITS.
APPLIANCE CAUTIONS
DO NOT plug small appliances into the inverter AC receptacles to directly recharge
their nickel-cadmium batteries. Always use the recharger provided with that appli-
ance.
Do NOT plug in battery chargers for cordless power tools if the charger carries a
warning that dangerous voltages are present at the battery terminals.
WARNING
NO USER-SERVICEABLE COMPONENTS INSIDE.

16. Connect an insulated wire (at least 12 AWG) between the grounding screw
on the inverter’s enclosure and a solid electrical ground to minimize possible
electrical noise generation in TVs and radios.
17. Check to ensure that all electrical connections are tight.
18. Ensure that the inverter’s ON/OFF switch is OFF.
19. Insert the fuse into the fuse holder. There may be some sparking.
20. Turn on the inverter and apply a test load to the AC outlets.
21. Observe the LED bar meters and ensure that adequate battery voltage is
present. If you have applied a 600 watt test load, the ammeter should display
50 amps. If it does not:
A.
Check all connections, and tighten any loose connections
B.
Ensure that the battery has an adequate charge
C.
Check the front panel voltmeter to see if adequate voltage is applied
If voltage is low, the cables may be too long or the gauge too light
D.
If steps A through C do not correct the problem, contact Vector Technical
Support Department (954) 584-4446 Ext. 19 for professional direction
22. Replace the terminal cover and secure with the screws.
5.6. Connection to High Output Terminal Block
External wiring connected to the high output terminal block REQUIRES a
user-supplied dual ganged 30 Amp circuit breaker to protect appliances.
FIGURE 9
shows typical wiring connections using a standard circuit breaker. There
are several types and many manufacturers of circuit breakers available; this
illustration is an example of only one type. A 30 amp Ground Fault Interrupter (GFI)
breaker should be used if the outlets or devices are around water.
Use a Square D type QO230GFICP Plug-On Circuit Breaker And Ground Fault
Interrupter. The physical size of this breaker requires a 70 Ampere load center box
rated at 120/240V single phase ( 3-wire Square D model HOM2-4L70S ). The
breaker has a pig-tail wire that must be connected to the grounding bar inside the
load center box. The Breaker is internally ganged so that both Neutral and Hot
circuits from the inverters’ High Output Terminal Block are switched simultaneously. If
you choose to use a conventional current-only circuit breaker, both Neutral and Hot
must be interrupted. You can use a 50 amp load center because a ganged non-
GFI breaker is physically smaller than a GFI breaker.
