3.2 MOUNTING REQUIREMENTS
1. TEMPERATURE
Make sure the GP-ISW is installed in a location where the normal air temperature is between
-20°C and 40°C. The cooler the better within this range.
2. MOISTURE
Do not allow water or other uids to come into contact with the GP-ISW. Do not expose to
rain, snow or water.
3. VENTILATION
For optimum Inverter performance the GP-ISW must be installed so the front and rear air vents
are not blocked or obstructed in any way. Do not install the GP-ISW in an area with limited
air ow. Allow as much space around the Inverter as possible, leaving at least 4 inches of
airspace clearance around all ventilation areas.
CAUTION! Equipment Damage. Do not mount the GP-ISW in a zero clearance
compartment. Do not cover the ventilation openings. Overheating and mechanical
failure may occur.
4. FIRE
Install the GP-ISW away from the battery bank, away from any ammable or combustible
material (paper, ammable liquids, gasoline, cloths) that may be ignited by heat, sparks or
ames. Never place the Inverter directly above the battery bank - gases from the batteries will
corrode and damage the Inverter, never allow battery acid to drip onto the unit.
5. ACCESSIBILITY / ORIENTATION
Do not block access to the GP-ISW remote control access port, status LEDs and the On/O
switch. Allow enough room to access the AC and DC wiring terminals and connections as
they will need to be checked and tightened periodically. The GP-ISW must be installed in one
of the approved mounting orientations detailed on page 20. DO NOT MOUNT VERTICALLY.
6. CLEAN
The GP-ISW should be installed in a location which is clean and limits the introduction of dust,
fumes, insects or rodents which could enter and block the Inverter ventilation openings.
7. PROXIMITY TO BATTERY BANK
The GP-ISW should be located as close to the batteries as possible but not within the same
compartment. The length and size of the DC Cables will aect performance. Long DC wires
tend to lose eciency and reduce the overall performance of the Inverter/Charger. Use the
DC cables recommended on page 23.

GP-ISW
DC Panel
The following points must be observed for the DC Wiring.
•
The DC positive and negative cables connected to the GP-ISW from the battery
bank should be linked together with zip ties or electrical tape every 6”. This helps
to reduce radio frequency interference and reduces the eects of inductance both
of which improve the Inverter waveform and reduces the wear of the Inverters
lter capacitors.
• To ensure optimum Inverter performance the number of connections between
the battery bank and the GP-ISW unit should be minimized except from the
over-current and battery disconnect devices. All additional connection points
will cause extra voltage drops.
• The Battery bank voltage must match the DC voltage required by the GP-ISW,
which is 12V or 24V (note that the Inverter is either 12V or 24V, and is not
switchable.
•
All DC cable wire terminations should use a crimped and sealed copper ring
terminal lugs.
• Make sure all cables have a smooth bend radius and no kinks are present.
•
Colour code all DC Cables coming to / from the battery bank. Use coloured
electrical tape or heat shrink tubing. Red for positive (+), Black for negative (-)
and Green for DC ground.
Page 23
gpelectric.com | [page 23]
INSTALLATION
3.3.1 DC WIRING SIZING
The distance between the battery bank and the GP-ISW should be as short as possible to
achieve maximum eciency and to reduce re hazards. The size of the cable should be thick
enough to limit the voltage drop to less than 2% when carrying the maximum input current to
prevent frequent low-input voltage warnings and shutdown. Only use high quality copper wire.
For greater eciency, the cables should be as short as possible. The combined cable length
should be no more than 10ft (3m). Keeping your wire runs as short as possible helps to prevent:
low voltage shutdowns and nuisance tripping of the DC breaker because of increased current
draw. The table below shows the recommended DC cable size, fuses/circuit breakers and
DC grounding cable sizes for the GP-ISW (Note: these values are correct for cables in free
air, not conduit)

3.3.2 DC OVERCURRENT PROTECTION AND DC DISCONNECT
Batteries are capable of providing very large currents in case of a short circuit, if this occurs
with no DC overcurrent protection, it will result in overheating and melting of the cables and
possibly serious injury and/or re.
DC overcurrent protection is not included with the GP-ISW Inverters. It must be installed
between the Inverter and battery bank for safety reasons and to comply with code regulations.
The fuse should be as close to the positive battery terminal as possible. Use Bussmann ANN
Class T series fuses (will also require Fuse Block 4164) or equivalent. Ideally the fuse/circuit
breaker should be installed within 18” (45cm of the battery). The fuse required for DC Cable
lengths up to 10ft is detailed in the above table.
In all installations a battery disconnect switch is required, if you install a circuit breaker for
overcurrent protection this will suce as a disconnect switch. If you install a fuse for overcurrent
protection then a separate disconnect switch will need to be installed.
3.3.3 PREPARING THE DC CABLES
Go Power! supplies 2 ring lugs with the GP-ISW which can be used for the Inverter end of the
DC Cables. Source the correct ring terminals for the batteries you are using.
• Cut the negative and positive cables to the required length.
• Strip o enough insulation so you can install the ring lugs provided.
• Use the correct crimp connector to install the ring lugs.
•
Attach the connectors to both ends of both cables. Make sure no stray wire
strands protrude from the connectors.
3.3.4 DC CABLE CONNECTIONS
When installing the battery cable ring lug onto the GP-ISW DC terminal and the battery post do not put anything between the ring lug and the metal surface. Incorrectly installed hardware
causes a high resistance connection which could lead to poor Inverter/Charger performance
and may melt the cable and terminal connections. Tighten the terminal connections securely
(torque to 9 – 10 ft-lbs, 11.7 – 13 Nm) and periodically check the connections to make sure
they remain tight and secure.
INSTALLATION
Page 25
gpelectric.com | [page 25]
To help prevent seizing and corrosion around the terminals the use of an anti-seize lubricant
is highly recommended. Apply the antioxidant grease or spray after all the connections are
made and tightened.
3.3.5 WIRING THE INVERTER TO THE BATTERIES
WARNING: Lethal currents will be present if the positive and negative cables attached
to the battery bank touch each other. During the installation and wiring process, ensure
the cable ends are insulated or covered to prevent shorting the cables.
WARNING: DO NOT connect the DC Wires from the battery bank to the GP-ISW until all
the DC and AC wiring is complete and the AC overcurrent protection has been installed.
The GP-ISW comes in 12V or 24V versions. Make sure the battery bank is wired in series,
parallel, or series-parallel to match the voltage of your inverter. The interconnecting wires
between the individual batteries must be sized and rated exactly the same as those used
between the battery bank and Inverter.
To ensure the best performance from your Inverter system, batteries should be the same size,
type, rating and age. Do not use old or untested batteries.
DC Positive and Negative Wires
•
Connect the negative cable from the battery bank negative terminal to the
Inverters negative terminal. Mount the DC circuit breaker or fuse assembly
and leave open (no power to the GP-ISW). Connect the positive cables from
the circuit breaker / fuse to the battery bank and to the Inverters positive terminal
(Note: DC circuit breaker and fuse not included).
•
Ensure the DC wire connections are ush on the surface of the DC terminals
and the hardware used to hold these connections are stacked correctly. Verify
all DC connections are secured tightly.
• Attach the red and black terminal covers over the Inverters DC connectors and
secure them in place with the supplied screws.

3.3.6 DC GROUNDING
To protect against electrical shock hazards the GP-ISW metal chassis must be connected to
the DC grounding system. The DC grounding system is sometimes referred to as the Earth
ground or another designated ground. For example on an RV, the metal frame of the RV is
designated as the negative DC ground / RV ground.
The DC ground wire connection on the GP-ISW is used to connect the exposed chassis of
the Inverter to the DC grounding system. Use copper wire that is either bare or provided with
green insulation. The size of this conductor should be coordinated with the size of the overcurrent devices used.
DC grounding involves proper grounding of the negative of the battery, the DC panel and the
DC side of the GP-ISW. The DC panel is normally used to connect the batteries and distribute
DC power to the Inverter and to the other DC loads.
A common earth ground should be used to bond the Inverter, negative bus bar and the negative battery terminal. All connections must be tight against bare metal. Use star washers to
penetrate paint and corrosion.
3.4 AC WIRING
The cables linking the GP-ISW to the appliances are the AC cables. The following points must
be observed for the AC Wiring
• Review the safety information at the start of this manual before completing any
AC wire installation steps.
•
All AC Wiring must be approved for the application (RV, Marine, Residential). For
RV applications, this may be solid wire in multi-conductor cables, but stranded
wire is required if single conductors are used.
• All wiring must be rated to 75°C or higher.
•
Do not connect the AC Output to an AC Power source (generator / shore power).
Severe damage may occur and will not be covered under the warranty.
• Always use properly rated circuit breakers / fuses.
• Make sure all cables have a smooth bend radius and no kinks are present.

3.4.2 GFCI (GROUND FAULT CIRCUIT INTERRUPTION) OUTLETS
Compliance with UL standards requires that Go Power! test and recommend specic GFCIs for
use on the AC output of the GP-ISW. GFCIs shall be installed in the AC output wiring system
to protect all branch circuits.
A GFCI is a device that de–energizes a circuit when a current exceeds a specied value that is
less than that required to open the circuit breaker. GFCIs are intended to protect people from
electric shocks and are usually required in wet or damp locations.
The table below lists GFCIs that have been tested and will function properly when connected
to the AC output of the GP-ISW.

4. OPERATION
4.1 FINAL INSPECTION
1.
Verify all cables / conduit runs are secured with zip ties or other non-conductive cable
clamps to prevent damage from vibration.
2. Ensure all cables that pass through walls, bulkheads or any other openings are protected
against abrasion by using strain reliefs and/or grommets.
3. Check all AC, DC and ground connections are securely tightened, and if required covered
with suitable anti-seizing grease.
4. Check all connections are secure in the main and sub panels - replace all covers.
5. If required by code, have the installation inspected by an electrical inspector.
4.2 TESTING THE INSTALLATION
1. Apply battery power to the inverter by engaging the fuse or switching the breaker to the
ON position.
2. Disconnect all AC loads from the inverter.
3.
Press the ON/OFF button. The inverter will carry out self-diagnosis and the LED’s will
also appear (various colors).
4.
Connect a 25W light bulb to the inverter output and verify it comes on and shines normally.
5. Press the ON/OFF button. The inverter and LED lights will turn o.
4.3 CONNECTING THE AC LOADS
Calculate the total power consumption of the output load. Make sure that the total power consumption does not exceed the rated power. If the total power consumption is higher than the
rated power of the inverter, remove the non-critical loads until the total power consumption is
below the rated power.
