Safety 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 ﬂ uid/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 (2.5 cm) 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.
