Preventing Dc input over Voltage
ItistobeensuredthattheDCinputvoltageofthisunitdoesnotexceed16.5VDCfor

nent damage to the unit. Please observe the following precautions:
- Ensurethatthemaximumchargingvoltageoftheexternalbatterycharger/alterna-
tor/solarchargecontrollerdoesnotexceed16.5VDCforthe12Vbatteryversionand
33.0VDCforthe24-Vbatteryversion
- Donotuseunregulatedsolarpanelstochargethebatteryconnectedtothisunit.

loads connected to the battery due to high voltages generated during conditions of

therefore,tobeensuredthatthediversionloadissizedcorrectlytopreventtheabove
over voltage conditions.
