Honeywell WT6500 owner manual Turbine Over-current Protection, Reverse Polarity Damage

SMARTBOX Installation 14

Turbine Over-current Protection

The NEC requires the turbine circuit to be protected with a device rated for 125% of the rating of the circuit. The DC-rated fuse or circuit breaker between the turbine and the SMARTBOX™ Controller must have a maximum size of 15 (the maximum current rating of the SMARTBOX™ Controller).

SHOCK HAZARD OR FIRE HAZARD Over-current protection must be installed to protect the SMARTBOX™ Controller from short circuits and to provide a means of disconnecting it. Failure to follow this warning may result in death, personal injury or property damage.

REVERSE POLARITY DAMAGE

Before making the final DC connection or closing the DC breaker or disconnect, check cable polarity at both the battery and the SMARTBOX™ Controller. Positive (+) must be connected to positive (+). Negative(-) must be connected to negative (-). Failure to follow this warning may result in death, personal injury or property damage.
