• Check the positive and negative polarity of the PV strings, and connect the PV connectors
to corresponding terminals only after ensuring polarity correctness.
• Arc or contactor over-temperature may occur if the PV connectors are not firmly
connected in place, and LIVOLTEK shall not be held liable for any damage caused due to
this operation.
• If the DC input is connected inversely and the DC switch has been rotated to "ON", do
not operate immediately. Otherwise, the equipment may be damaged. Please turn the
DC switch to "OFF" and remove the DC connector to adjust the polarity of the strings
when the string current is lower than 0.5A.
6.6 Battery Connection
This section mainly describes the cable connections on the inverter side. Refer to the instructions
supplied by the battery manufacturer for the connections on the battery side and configuration.
• Be careful against any electric shock or chemical hazard.
• A short circuit in the battery may cause personal injury. The instantaneous high current
caused by a short circuit can release a large amount of energy and may cause a fire.
• Ensure that the open circuit voltage of the battery is within the permissible range of the
inverter.
• Only use properly insulated tools to prevent accidental electric shock or short circuits. If
insulated tools are not available, use electrical tape to cover the entire exposed metal
surfaces of the available tools except their tips.
• Before connecting the battery cable, ensure the switches of inverter and the battery are
all disconnected.
• Connect battery cables with correct polarity. If battery cables are reversely connected,
the solar inverter may be damaged.
• It is forbidden to connect and disconnect the battery cables when the inverter is running,
otherwise it may cause electric shock.
• Do not connect one battery pack to more than one inverter at the same time. Otherwise,
it may cause damage to the inverter.
• It is forbidden to connect loads between the inverter and batteries.
• All wiring must be performed by a professional person.
