General Safety and Usage Recommendations
Intended Use
The charge controller is intended exclusively for use in photovoltaic systems with 12 V nominal voltage, and
in conjunction with vented or sealed (VRLA) lead acid batteries only.
Safety Recommendations
z Batteries store a large amount of energy. Never short circuit a battery under any circumstances. We
recommend connecting a fuse (slow acting type) directly to the battery.
z Batteries can produce flammable gases. Avoid making sparks, using fire or any naked flame under any
circumstances. Make sure that the battery room is ventilated.
z
Avoid touching or short circuiting wires or terminals. Be aware that the voltages on specific
terminals or wires can be up to double the battery voltage. Use isolated tools, stand on dry ground
and keep your hands dry.
z Keep children away from batteries and the charge controller.
z Please observe the safety recommendations of the battery manufacturer. If in doubt, consult your
dealer or installer.
Liability Exclusion
The manufacturer shall not be liable for damages, especially on the battery, caused by use other than as
intended or as mentioned in this manual or if the recommendations of the battery manufacturer are neglected.
The manufacturer shall not be liable if there has been service or repair carried out by any unauthorized
person,
