Personal Safety
WARNING!
Personal Injury
Use safe lifting techniques when lifting this equipment as
recommended by the Occupational Safety and Health
Association (OSHA) or other local codes.
Use standard safety equipment when working on this
equipment, such as safety glasses, ear protection, steel-
toed safety boots, safety hard hats, etc.
Use standard safety practices when working with electrical
equipment. (Remove all jewelry, use insulated tools, wear
cotton clothing, etc.)
Never work alone when installing or servicing this
equipment. Have someone nearby that can assist if
necessary.
Ensure that children, pets, and other animals are kept away
from the inverter, solar arrays, battery bank, and utility grid
components.
If the equipment is used in a manner not specied by the
manufacturer, the protection provided by the equipment may
be impaired.

GENERAL INFORMATION
Equipment Safety
WARNING!
Lethal Voltage
Review the system conguration to identify all possible
sources of energy. Ensure ALL sources of power are
disconnected before performing any installation or
maintenance on this equipment. Conrm that the terminals
are de-energized using a validated voltmeter (rated for
a minimum 1000 VAC and 1000 VDC) to verify the de-
energized condition.
Do not perform any servicing other than that specied in the
installation instructions unless qualied to do so, or have
been instructed to do so by Go Power! Technical Support
personnel.
To avoid electric shock, disconnect the DC input and AC
input of the inverter at least 5 minutes before performing any
installation or maintenance.
Do not tighten the AC and DC terminals or pull on the AC and
DC wiring when the inverter is running.
WARNING!
Fire Hazard
Do not keep combustible or ammable materials in the same
room with the equipment. Some products contain relays with
moving parts and are not ignition-protected.
Ensure AC, DC, and ground cable sizes conform to local
codes. See product manuals for minimum size requirements.
Ensure all conductors are in good condition.
Do not operate the unit with damaged or substandard cabling.
CAUTION!
Equipment Damage
When connecting cables from the inverter to the battery
terminals, ensure the proper polarity is observed. Connecting
the cables incorrectly can damage or destroy the equipment
and void the product warranty.
Thoroughly inspect the equipment prior to energizing. Verify
that no tools or equipment have been inadvertently left
behind.
Keep all vents clear of obstructions that can prevent proper air
ow around, or through, the unit.
CAUTION!
Equipment Damage
Static electricity may damage electronic components. Take
appropriate steps to prevent such damage to the inverter;
otherwise the warranty may be annulled.

GENERAL INFORMATION
Battery Safety
WARNING!
Explosion, Electrocution,
or Fire Hazard
Ensure the cables (conductors) are properly sized.
Ensure clearance requirements are strictly enforced around
the batteries.
Ensure the area around the batteries is well ventilated and
clean of debris.
Never smoke, or allow a spark or ame near, the batteries.
Always use insulated tools. Avoid dropping tools onto
batteries or other electrical parts.
Never charge a frozen battery.
Never use old or untested batteries. Check each battery’s
label for age, type, and date code to ensure all batteries are
identical.
If a battery must be removed, always remove the grounded
terminal from the battery rst. Make sure all devices are de-
energized or disconnected to avoid causing a spark.

gpelectric.com | [page 9]
IMPORTANT
Use the battery types recommended by Go Power. Follow
the battery manufacturer’s recommendations for installation
and maintenance.
Insulate batteries as appropriate against freezing
temperatures. A discharged battery will freeze more easily
than a charged one.
If a remote or automatic generator control system is used,
disable the starting circuit and/or disconnect the generator
from its starting battery while performing maintenance to
prevent accidental starting.
Wear complete eye and clothing protection when working
with batteries. Avoid touching bare skin or eyes while working
near batteries.
Keep plenty of fresh water and soap nearby in case battery
acid contacts skin, clothing, or eyes.
If battery acid contacts skin or clothing, wash immediately
with soap and water. If acid enters the eye, immediately
ood it with running cold water for at least 20 minutes and get
medical attention as soon as possible.
CAUTION!
Equipment Damage
When connecting cables from the inverter to the battery
terminals, ensure the proper polarity is observed. Connecting
the cables incorrectly can damage or destroy the equipment
and void the product warranty.
Thoroughly inspect the equipment prior to energizing. Verify
that no tools or equipment have been inadvertently left
behind.
Ensure clearance requirements are strictly enforced.
Keep all vents clear of obstructions that can prevent proper
air ow around, or through, the unit.
CAUTION!
Equipment Damage
Static electricity may damage electronic components. Take
appropriate steps to prevent such damage to the inverter;
otherwise the warranty may be annulled.

3.1 TYPICAL SYSTEM OVERVIEW
The following diagrams on pages 16-19 show how the GP-ISW-Inverter and GP-ISW-R are
typically installed in a mobile RV application. The diagrams show where the remote and Inverter
are installed and how the mobile power system can be integrated with a Go Power! RV Solar
Kit (sold separately by Go Power, please contact an authorized dealer directly).

[page 20] | gpelectric.com
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 a󰀨ect performance. Long DC wires
tend to lose e󰀩ciency and reduce the overall performance of the Inverter/Charger. Use the
DC cables recommended on page 23.
INSTALLATION
