3 Wiring
Installation Procedure:
Connect the system in the order of ❶battery ❷ load  ❸PV array in
accordance with Figure 2”Connection diagram” and disconnect the system in the reverse
order❸❷❶.
NOTE: The LS-B series is a positive ground controller. Any positive
connection of solar, load or battery can be earth grounded as required.
NOTE:While wiring the controller do not close the circuit breaker or fuse
and make sure that the leads of "+" and "-" poles are connected correctly.
NOTE: A fuse which current is 1.25 to 2 times the rated current of the
controller must be installed on the battery side with a distance from the
battery not greater than 150 mm.
NOTE: If an inverter is to be connected to the system, connect the inverter
directly to the battery, not to the load side of the controller.
