Page 8: Safety Instructions And Warnings
4.Safety Instructions and Warnings The Charger should be installed in a location that meets the following requirements. 1.Dry- Do not allow water to drip or splash on the charger 2.Cool- Ambient air temperature should be between 0 and 40°C, the cooler the better. 3.Safe- Do not install in a battery compartment or other areas engine compartments. -
Page 9: Maintenance
Also do not mount the charger where it will be exposed to the gases produced by the battery. These gases are very corrosive and prolonged exposure also will damage the charger. WARNING! Shock Hazard. Before proceeding further, carefully check that the charger is NOT connected to any batteries, and that all wiring is disconnected from any electrical sources. -
