Step 4：Grounding
Tracer-AN series are common-negative controllers. Negative terminals of the PV array, the battery can
be grounded simultaneously, or any terminal is grounded. However, according to the practical application,
the PV array's negative terminals, battery, and load can also be ungrounded. Simultaneously, the
grounding terminal on the shell must be grounded, which effectively shields the electromagnetic
interference from the outside and prevents some electric shock to the human body.
It is recommended to use a common-negative controller for common-negative
systems, such as the RV system. The controller may be damaged if a
common-positive controller is used and the positive electrode is grounded in the
CAUTION
common-negative system.
Step 5：Connect accessories
 Connect the remote temperature sensor cable (Model: RTS300R47K3.81A)
Connect the remote temperature sensor cable to the interface ❽ and place the other end
close to the battery.
Suppose the remote temperature sensor is not connected to the controller. In that
case, the controller can charge or discharge the battery at the default 25 º C(no
CAUTION
temperature compensation).
 Connect the remote battery voltage sensor cable (Model: RVBS300B3.81)
Connect the remote battery voltage sensor cable to the interface⓫ and connect the other end to the
battery terminals.
 Connect the accessories for RS485 communication; refer to the accessories list.
Step 6：Power on the controller
Connect the battery fuse to power the controller. After the LCD normally displays, connect the PV array's
circuit breaker. The charging indicator is slow flashing during the PV charging process.
If the controller cannot work properly or the fault indicator shows an abnormality,
please refer to
