Warning:
A thermal circuit breaker or fuse must be installed between the battery supply and
the controller, to protect both the batteries and the system wiring. This shall be
mounted as close as possible to the battery terminals as per ISO7176-14
requirements.
The thermal circuit breaker should have a trip rating no higher than the current limit
of the controller or the protection wire. Check thoroughly to ensure that it provides
the necessary degree of motor protection.
If the two batteries are permanently wired
together (for example in a single battery box),
the best position for the circuit breaker is
between the two batteries. If the batteries are
separated (individual battery boxes), each
battery requires a circuit breaker or fuse. A slow-
acting, thermal type circuit breaker is suggested.
Make sure that the protection system is in
compliance with ISO7176-14 requirements.
