Connecting Power Cables

Caution – A qualified service person is required to make the DC power connection per NEC and CEC guidelines. A two-pole20-amp circuit breaker is required between the DC power source and the array module for over-current and short-circuit protection. Before turning off any power switches on a DC-powered module, you must disconnect the two-pole20-amp circuit breaker.
