Connect one end of the remote temperature sensorcable
Step 2：Connect the system in the order of ❶battery ❷ load ❸PV array in
accordance with Figure 2-2,”Schematic Wiring Diagram” and disconnect the system in
the reverse order❸❷❶.
CAUTION: While wiring the controller do not close the circuit breaker or
fuse and make sure that the leads of "+" and "-" poles are connected
correctly.
CAUTION: 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.
CAUTION: If the controller is to be used in an area with frequent lightning
strikes or unattended area, it must be installed an external surge arrester.
CAUTION: 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.
Step 3：Grounding
MAX series is a common-negative controller, where all the negative terminals of PV
array, battery and load can be grounded simultaneously or any one of them will be
grounded. However, according to the practical application, all the negative terminals of
PV array, battery and load can also be ungrounded, but the grounding terminal on its
shell must be grounded, which may effectively shield the electromagnetic interference
from the outside, and prevent some electric shock to human body due to the
electrificationof the shell.
CAUTION: For common-negative system, such as motorhome, it is
recommended to use a common-negative controller; but if in the
common-negative system, some common-positive equipment are used,
and the positive electrode is grounded,the controller may be damaged.
