WARNING - WORKING IN THE VICINITY OF A LEAD ACID BATTERY IS DANGEROUS. BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL OPERATION. Design the battery enclosure to prevent accumulation and concentration of hydrogen gas in “pockets” at the top of the enclosure. Vent the battery compartment from the highest point to the outside. A sloped lid can also be used to direct the flow of hydrogen to the vent opening. CAUTION - To reduce risk of injury, charge only deep-cycle lead acid, lead antimo

. Powering Up The FLEXmax 80 power-up sequence first activates the unit and the SELECT VERSION screen (to de- termine a choice of English, Espanola, or Australian settings). A SYSTEM VOLTAGE screen soon follows. However, when it auto-detects the system’s battery voltage, in some instances the FLEXmax 80 might not reflect the correct system voltage (e.g., if a 36VDC system falls to a voltage range that could be misread as a 24VDC system). The SYSTEM VOLTAGE screens allow the user to adjust th
