snow, moisture, or liquids of any type.
• Use insulated tools to reduce the chance of electrical shock or accidental short circuits.
• There are no user-serviceable parts contained in this product.
• This unit is provided with integral protection against overloads.
• Live power may be present at more than one point since an inverter utilizes both DC (batteries,
PV, etc.,) and AC (utility or generator) power. To reduce risk of electric shock, ensure all DC
and AC wiring is disconnected prior to installing or performing maintenance on the inverter.
Turning off the inverter will not reduce this risk, the inverter must be totally disconnected from
all sources.
• Use Class 1 wiring methods for field wiring connections to terminals of a Class 2 circuit.
• Listed or labeled equipment shall be installed and used in accordance with any instructions
included in the listing or labeling.
• Always verify proper wiring prior to starting the inverter.
• Use only copper wires with a minimum temperature rating of 75°C.
• AC wiring must be no less than 10 AWG (5.3 mm²) gauge copper wire.
• Battery cables should be no less than #4/0 AWG for 12 and 24-volt systems. Crimped and
sealed copper ring terminal lugs with a 5/16 hole should be used to connect to the DC
terminals on the inverter.
• Torque all AC wiring connections and DC cable connections to the required torque values.
• The inverter must be properly mounted, see Section 2.2 “Mounting the Inverter” in this
manual.
• Overcurrent protection for the battery supply is not provided as an integral part of this
inverter. Overcurrent protection of the battery cables must be provided as part of the system
installation. Refer to Section 2.4 “DC Wiring” for more information.

• Overcurrent protection for the AC output wiring is not provided as an integral part of this
inverter. Overcurrent protection of the AC output wiring must be provided as part of the
system installation. Refer to Section 2.5 “AC Wiring” for more information.
• The AC output neutral conductor and the DC negative conductors are not connected (bonded)
to the inverter chassis. Both the input and output conductors are isolated from the enclosure
and each other. System grounding, if required, is the responsibility of the system installer and
must comply with local and national electrical codes and standards. Refer to the Section 2.6
“Grounding Inverters” for more information.
Battery Safety
• Use insulated tools and be very careful when working around batteries, they can produce
extremely high currents if short-circuited (e.g., dropping a metal tool across the battery
terminal), which could cause a fire or explosion.
• Read and follow the battery manufacturer’s safety precautions before installing the inverter
and batteries. Always verify proper polarity and voltage before connecting the batteries
to the inverter. Once the batteries are connected to the inverter, ensure the maintenance
and charging requirements (i.e., charge voltage and charge rate) provided by the battery
manufacturer are followed to extend the life of the batteries and to prevent damage to the
batteries while charging.
• Wear eye protection such as safety glasses, and avoid touching your eyes and face when
working with batteries to keep any fluid/corrosion on the battery from coming in contact
with eyes and skin. Have plenty of fresh water and soap nearby and thoroughly wash in case
battery acid contacts skin, clothing, or eyes. In the event of exposure to the eyes, flood them
for at least 15 minutes with running water and seek immediate medical attention. Baking soda
neutralizes lead acid battery electrolyte and vinegar neutralizes spilled NiCad and NiFe battery
electrolyte; depending on your battery type, keep a supply on hand near the batteries.
• Remove all jewelry such as rings, watches, bracelets, etc., when installing or performing
maintenance on the batteries and inverter. A battery can produce a short-circuit current high
enough to weld metal jewelry, causing severe burns.
• Never work alone. Always have someone within the range of your voice or close enough to
come to your aid when working around batteries.
• Use proper lifting techniques when working with batteries.
• Never use old or untested batteries. Check each battery’s label for age, type, and date code
to ensure all batteries are identical.
• Batteries are sensitive to changes in temperature. Install batteries in a stable environment.
• Batteries can produce explosive gasses, so install batteries in a well-ventilated area. For
compartment or enclosure installations, always vent batteries from the highest point to the
outside. Design the battery enclosure to prevent accumulation and concentration of hydrogen
gas in “pockets” at the top of the compartment.
• Provide at least one inch of air space between batteries to provide optimum cooling.
• Never smoke or allow a spark near batteries.
• To prevent a spark at the battery and reduce the chance of explosion, always connect the
cables to the batteries first. Then connect the cables to the inverter.
• Never charge a frozen battery.
• The battery bank should be installed in a clean, dry, ventilated environment where they are
protected from high and low temperatures. If installed in a vehicle/boat, the batteries must be
mounted upright (if using liquid batteries) and securely fastened. The location must be fully
accessible and protected from exposure to heat producing devices, and away from any fuel
tanks.
