3.2 Wiring

NOTE: A recommended connection order has been provided for
maximum safety during installation.
NOTE: There are two types of the controller: common positive
controller and common negative controller.
CAUTION: Don't connect the loads with surge power exceeding the
ratings of the controller.
CAUTION: For mobile applications, be sure to secure all wiring.
Use cable clamps to prevent cables from swaying when the vehicle is
in motion. Unsecured cables create loose and resistive connections
which may lead to excessive heating and/or fire.
WARNING: Risk of explosion or fire! Never short circuit battery
positive (+) and negative (-) or cables.
WARNING: Risk of electric shock! Exercise caution when handling
solar wiring. The solar module(s) high voltage output can cause
severe shock or injury.
wiring.
Before battery is connected, make sure that voltage of battery is higher than 9V so as to
start the controller. If nominal system voltage is 24V, make sure that voltage of battery is
no less than 18V; if nominal system voltage is 48V, make sure that voltage of battery is no
less than 42V. The nominal system voltage can only be automatically identified when
controller is started for the first time.
