Preparing for Installation

WARNING: This device is not ignition protected, risk of fire or explosion
This equipment contains components that could produce arcs or sparks. To reduce the risk of fire or
explosion, do not install this equipment in compartments containing batteries, flammable materials or
fumes, or in a location containing gasoline-powered machinery, or joints, fittings, or other connections
between components of the fuel system.
WARNING: Do not mount the inverter above or below your batteries.
WARNING: Electrical shock and fire hazards
On Board Solutions recommends all wiring be done by qualified personnel. Disconnect all AC and DC
power sources to prevent accidental shock. Disable and secure all AC and DC disconnect devices and
automatic generator starting devices. It is the installer's responsibility to ensure compliance with all the
applicable installation codes and regulations.
WARNING: Installation precaution
The TruePower Plus Inverter should be mounted on a flat horizontal surface or a vertical surface. In no
case should the front or rear end caps be facing in an upward or downward position. This allows proper
ventilation and product safety of the unit as intended by design.
WARNING: Fire hazard
Do not cover or obstruct the ventilation openings. Do not install this equipment in a compartment with
limited airflow; Overheating may result.
WARNING: Risk of fire or explosion
WARNING: Low voltage - electrical burn and spark hazard.
Disconnect battery power before servicing.
NOTE: This unit requires a large amperage draw from a DC battery when in inverter mode. Care must be
taken during installation to provide properly sized cables from the battery to the inverter. Cable runs must
be as short as possible and of the appropriate size and type. See the Installation section for more details.
Installation Recommendations and Requirements Include the Following:
American Boat and Yacht Council (ABYC)
The Canadian Electrical Code (CEC)
Canadian Standards Association (CSA)
The U.S. National Electrical Code (NEC)
RV Industry Association (RVIA)
Required Tools and Materials
You will need the following to install the inverter unit:
- Two 7/16" box wrenches (1000-1500 watt models)
- Two 1/2" box wrenches (2000 watt models)
- Wire strippers
- Phillips-head screwdriver
- Flat-head screwdriver
- Properly sized DC cabling
- Mounting hardware
Inverter Unit Location
NOTE: On Board Solutions highly recommends that this unit be installed by a Certified Electrical
Technician. Guidance from ABYC E-11 AC & DC Electrical Systems and ABYC A-31 Battery
Chargers & Inverters is offered throughout this manual to ensure a safe, trouble free installation.
Please re-read the PERSONAL PRECAUTIONS section of this manual prior to installation.
This unit must be located in a cool, dry, well ventilated area, free from unsecured hardware. Temperature
is also a serious consideration. Do not mount this unit in an engine compartment or areas where
temperatures will exceed 40° C (104° F).
In addition, the following should be considered when choosing a location:
1) Locate inverter unit away from battery in a separate, well ventilated compartment.
2) Placement of the remote status panel - A length of communications cable is provided for
remote-location of the status/on/off panel. Ensure the cable is long enough to reach the desired
location (generally in proximity to the main panel board) and avoid any area where it can be damaged.
3) Service - Remember, there are items on this unit that should be routinely checked (connections,
LED Status Center) to ensure that there is ample room to address these issues. Also consider
space to adequately swing a standard wrench.
4) Cable Routing - Large DC cables and over current protection (fuses/circuit breakers) will be
located in proximity to this unit. Choose a location as CLOSE AS POSSIBLE to the DC battery
bank serving the unit. This will provide optimum performance for the unit and keep cable sizes smaller.
Location of the AC power is less critical than the DC supply. More information on cable sizing follows.
MOUNTING - This unit must be mounted securely to an appropriate surface (e.g. plywood bulkhead,
cored fiberglass hull structure) and through-bolted if possible.
