NOTE: A recommended connection order has been
provided for maximum safety during installation.
NOTE: the controller is common negative one.
CAUTION: Don’t connect the loads with surge power
exceeding the ratings.
CAUTION: Secure all wiring for mobile applications. Use
cable clamps to prevent cables from swaying. 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. Be careful
operation when installing solar wiring.
If nominal system voltage is 12V, make sure battery voltage is higher than 9V before
starting the controller. If nominal system voltage is 24V, make sure voltage of battery is
no less than 18V; if nominal system voltage is 36V, make sure voltage of battery is no
less than 30V; if nominal system voltage is 48V, make sure voltage of battery is no less
than 42V. The nominal system voltage can only be identified when controller is powered
