Safety 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 2.10
“MMP/Inverter System Grounding” 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
fi
re 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,
fl
ood 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. Always 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
fi
rst. Then connect the cables to the inverter.
• Never charge a frozen battery.
