4.0 Maintenance and Troubleshooting
The following information is provided to help you keep your MSH-RE Series inverter/charger in
optimum operational condition.
4.1 Recommended Inverter and Battery Care
The MSH-RE Series inverter/charger is designed to provide you with years of trouble-free service.
Even though there are no user-serviceable parts, it is recommended that every 6 months you
perform the following maintenance steps to ensure optimum performance and extend the life of
your batteries.
WARNING:
Prior to performing any checks, switch off the AC and DC circuits.
• Visually inspect the batteries for cracks, leaks, or swelling—replace if necessary
• Use baking soda to clean and remove any electrolyte spills or buildups
• Check and tighten all battery hold-down clamps (if applicable)
• Clean and tighten all battery terminals and connecting cables [10 to 12 ft lbf (13.6 to 16.3
N-m)]
• Check
and
fi
ll battery water levels (liquid lead acid batteries only)
• Check individual battery voltages (load test those that have a voltage difference of more
than 0.3 VDC from each other)—replace if necessary
• Check all cable runs for signs of cha
fi
ng—replace if necessary
• Check the inverter’s cooling vents—clean as necessary
• Check/tighten the inverter’s internal AC terminal block connections [32 in lbf (3.6 N-m)]
WARNING:
If an automatic generator start device were to start and run the generator
for an extended period of time in a con
fi
ned area, a potentially fatal level of CO (carbon
monoxide) could accumulate.
