1) Determine the Installation Location and Heat-dissipation Space
Determination of installation location: The controller shall be installed in a place with sufficient air flow through the radiators
of the controller and a minimum clearance of 150mm from the upper and lower edges to ensure natural thermal convection.
2) Determine the size of Installation Location (158*96mm)
Step 1: Connect the battery
CAUTION: A fuse in 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.
Step 2: Connect the PV
CAUTION: While wiring the controller do not turn on the
breaker or fuse and make sure that the leads of “+” and “-”
poles are connected correctly.
CAUTION: If the controller is used in an ungoverned or
frequent lightning area, must install a reasonable arrester in
the PV array input side.
Step 3: Connect the Remote temperature sensor cable
NOTE: The controller will charge or discharge the battery at
25
o
C
as default and no temperature compensation when the
temperature sensor is damaged.
Step 4: Connect the Remote battery voltage sensor
CAUTION: Make sure that the battery voltage sensor cable
of “+” and “-” poles are connected correctly when wiring.
Step 5: Connect the PC via the RS485 communication
port
Refer to chapter 4 “Remote set battery type”.
3) Cut out the section (158*96mm)
4) Mark holes and drill holes

3.5mm*4
5) Secure the controller
6) Install the control case
