The wiring terminals on the controller can be connected with a single battery or a pack of
batteries. Following descriptions in this manual apply to systems employing either a single
battery or a pack of batteries.
Follow the safety advice given by the battery manufacturer.
When selecting connection wires for the system, follow the criterion that the current density
is not larger than 4A/mm².
Connect the controller’s earth terminal to the ground.
Wiring and other installation methods must comply with national and local electrical specifications.
The wiring specifications of the battery and loads must be selected according to rated currents, and
see the following table for wiring specifications:
30A
20A
6mm²
5mm²
WARNING! RISK OF EXPLOSION!
Never install the controller and an
open battery in the same enclosed space! Nor should the controller
be installed in an enclosed space where battery gas may accumulate.
WARNING! DANGER OF HIGH VOLTAGE!
Photovoltaic arrays may
produce a very high open-circuit voltage. Open the breaker or fuse
before wiring and be very careful during the wiring process.
Note:
when installing the controller, make sure that enough air flows
through the controller’s radiator, and have at least 150mm of space
both above and below the controller to ensure natural convection for
heat dissipation. If the controller is installed in an enclosed box, make
sure the box delivers reliable heat dissipation effect.
1.
Choose the installation site. Do not install the controller at a
place that is subject to direct sunlight, high temperature or
water intrusion and ensure the ambient environment is well ventilated.
2.
Place the installation guide plate at a proper position, use a marking pen to mark the
mounting points, then drill 4 mounting holes at the marked points, and fit screws in.
3.
Fix the controller. Aim the controller’s fixing holes at the screws marked in step 2 and mount
the controller on.
