SMARTBOX™ Controller for HONEYWELL™ Wind Turbine WT6500 Owner's Manual - Rev14
The NEC/CEC requires the battery 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 battery
and the SMARTBOX™ Controller must have a maximum size of 75A (the maximum
current rating of the SMARTBOX™ Controller).
SHOCK 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.
