SAFETY INFORMATION
WF-5200-AD Series Pure Sine Wave Inverter
• Do not expose the Inverter to rain, snow, spray, bilge or dust. To reduce risk of hazard, do not
cover or obstruct the ventilation openings. Do not install the inverter in a zero-clearance
compartment. Overheating may take place.
• To avoid a risk of re and electric shock, please make sure that existing wiring is in good
electrical condition; and that wire size is not undersized. Do not operate the Inverter with
damaged or substandard wiring.
• This equipment contains components which can produce arcs or sparks.
• To prevent re or explosion do not install in compartments containing batteries or ammable
materials or in locations which require ignition protected equipment. This includes any
space containing gasoline-powered machinery, fuel tanks, joints, ttings, or other connection
between components of the fuel system.
• An over current protection at the time of installation shall be provided by others for the AC
output circuit.
• Additional breakers suitable for 20 A branch circuit protection shall be provided for the
GFCI receptacles.
PRECAUTIONS WHEN WORKING WITH BATTERIES
• If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters
eye, immediately wash eyes with running cold water for at least 20 minutes and get medical
attention immediately.
• Never smoke or allow a spark or ame in vicinity of battery or engine.
• Do not drop a metal tool on the battery. The resulting spark or short-circuit on the battery or
other electrical part may cause an explosion.
• Remove personal metal items such as rings, bracelets, necklaces and watches when working
with a lead-acid battery. A lead-acid battery produces a short-circuit current high enough to
weld a ring or similar item to metal causing a severe burn.

INSTALLATION
The power inverter should be installed in a location that meets the following requirements:
• Dry – Do not allow water to drip or splash on the inverter.
• Cool – Ambient air temperature should be between -20°C and 50°C, but the cooler the better.
• Safety – Do not install batteries in the compartment or other areas near ammable fumes such
as fuel storage areas or engine compartments.
• Ventilated – Allow at least one feet of clearance around the Inverter for air ow. Ensure the
ventilation shafts on the rear and bottom of the unit are not obstructed.
• Dust-free – Do not install the Inverter in dusty environments here dust, wood particles or
other lings/shavings are present. The dust can be pulled into the unit when the cooling fan is
in operation.
• Close to batteries – Avoid excessive cable lengths but do not install the inverter in the same
compartment as batteries.
• Use the recommended wire lengths and sizes (refer to section 4.DC wiring connections).
• Do not mount the inverter where it is exposed to the gases produced by the battery. These
gases are very corrosive and prolonged exposure will damage the inverter.
Shock Hazard. Before proceeding further, carefully check that the inverter is NOT connected to
any batteries, and that all wiring is disconnected from any electrical sources. Do not connect the
output terminals of the inverter to an incoming AC source.

POWER ON / OFF / REMOTE (MAIN) SWITCH
• Please make sure the inverter turns off before installation.
• The input comes from AC Grid can’t be controlled by switch. Please disconnect the AC Grid
when you operate the main inverter unit in order to avoid the electric shock.
AC Output (Please refer to hard wiring installation)
AC output socket (please refer to 4-2)
AC INPUT CIRCUIT BREAKER - The AC input circuit breaker protects the model from overload.
When an overload condition exists, the circuit breaker stops supplying output AC grid power.
The breaker will recover automatically.
CHASSIS GROUND: CONNECT THE WIRE # 8 AWG TO VEHICLE CHASSIS
Operating the inverter without a proper ground connection may cause electrical safety hazard.

LCM port is for remote control connection only. Please make sure the connection is correct. (CAN
cable to CAN1 / CAN2 port , Remote cable to LCM port) If CAN cable is connected to LCM port,
or vice versa, the inverter will be damaged.

NOTE: The cables should be as short as possible (less than 32.8 feet / 10 meters) so that they
can handle the signal.

LCM PORT
Connection for LCD remote control panel, you can set

THE R20DIS EQUIPPED WITH THE FOLLOWING FEATURES:
LED Indicator - The LED provides the inverter status in a straightforward way.
LCD Display - The LCD display is a 16 x 2 line alphanumeric display used for setting up the
inverter/charger operation, as well as, viewing current status or fault messages.
ON/OFF Pushbutton - To turn on/off UNIT quickly
Four Buttons - Click buttons allows you to select a menu item or to save a setting, once it is
displayed on the LCD screen.
Turning the unit OFF does not mean to disconnect the batteries or AC Power Source. Therefore
the “AC output load” is still active. Only use the remote control cable supplied, using different
cables could cause permanent damage to the inverter unit

INSTALLATION GUIDELINES
• Please determine the remote cable route throughout the home or vehicle/boat, both to and
from the inverter before connecting any wires.
• Always check for existing electrical, plumbing, or other areas of potential damage before
drilling or cutting into walls to mount the remote.
• Make sure all wires have a smooth bend radius and do not become kinked.
• Please ensure the conductors passing through walls, bulkheads, or other structural members
are protected. This minimizes insulation damage such as chang, which can be caused by
vibration or constant rubbing when installing this remote in a boat, RV, or truck.
INSTALLATION OVERVIEW
The remote is required in order to connect the inverter. Each inverter must be connected directly
to the remote using the supplied RJ11 communication cables. The remote must be located close
to the inverters within nine meters and acts as the system control panel.
MOUNTING THE INVERTER
• Select an appropriate location to install the remote.
• Mount the remote base to the wall using the four screws provided.
CONNECTING THE RJ-11 CABLE
Please use RJ-11 cable supplied with remote to connect to inverter. See below indication.

PROTECTION FEATURES
Connect the cables to the power input terminals on the front panel of the inverter. The red
terminal is positive (+) and black terminal is negative (-). Insert the cables into the terminals and
tighten the screw to clamp the wires securely.
• Make sure all the DC connections are tight (torque to 11 ft-lbs, 15 Nm Max.). Loose
connections could overheat and result in a potential hazard.
• The installation of a fuse must be on the positive cable. Failure to place a fuse on “+” cables
running between the inverter and battery may cause damage to the inverter and will
void warranty.
• Also, only use high quality copper wire and keep the cable length short - maximum of
three - six feet.
DC WIRING CONNECTIONS

Do not place anything between battery cable
lug and terminal surface. Assemble exactly as shown.
During the rst installation, a small spark is a normal phenomenon because the internal
capacitors charging. Do not be concerned.
DC INPUT TERMINALS
Connect DC input terminals to 12V / 24V / 48V battery or other power sources. [ + ] represents
positive, [ - ] represents negative. Reverse polarity connection can blow the internal fuse and may
damage the inverter permanently.
