2.3 Installation and Wiring
Warning: Explosion risk. Do not install the solar charge controller and
open type cell in the same closed space. Do not install in closed place where
battery gas may gather.
Warning: High pressure danger. Photovoltaic array may generate very
high open circuit voltage. Before wire connection, disconnect the breaker or
insurance. Be careful in the process of wiring.
Attention: When installing a solar charge controller, make sure there is
enough air flowing through the cooling fin of the controller. Leave a space of at
least 150 mm up and down the solar charge controller to ensure natural heat
loss through convection. If installed within a closed cabinet, ensure reliable heat
dissipation through the cabinet body.
