8. Troubleshooting
• Your Inverter/Charger requires no maintenance and contains no user-serviceable or user-replaceable parts, but should be
kept dry at all times. Periodically check, clean and tighten all cable connections as necessary, both at the unit and at the
battery.
• A small-size battery being charged at a higher charging rate could cause an overvoltage shutdown. To prevent this, reduce
the charge rate or discharge the battery before recharging.
• If the Inverter does not start up properly, disconnect the system from the battery for 30 seconds, then repeat the startup
procedure. If the system still does not start up properly, visit www.tripplite.com/support.
