per NEC and CEC guidelines. A two-pole 20-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-pole 20-amp circuit breaker.
Caution – Electrical grounding hazard – This equipment is designed to permit the
connection of the D.C. supply circuit to the earthing conductor at the equipment.
