SMARTBOX Installation
SMARTBOX™ Controller for HONEYWELL™ Wind Turbine WT6500 Owner’s Manual - Rev14
Grounding
The SMARTBOX™ Controller is designed to work only with the HONEYWELL™
Wind Turbine. The turbine uses a negative-grounded electrical system. Grounding for
the turbine, battery and AC circuits are provided inside the wiring compartment. Each
ground connection can accommodate up to #6 AWG wire size.
GFI: A fuse rated at .5A 250V, accessible from the bottom of the wiring compartment,
grounds the negative conductor of the turbine and provides turbine ground-fault
protection. Only a Littelfuse 0312.500HXP or equivalent fuse should be used as a
replacement.
SHOCK HAZARD
DO NOT connect the battery negative to ground. NEC
requirements specify that the battery negative ground must
be done only through the 1A fuse. Bonding the battery
negative to ground will disable the turbine’s ground fault
protection and will result in improper operation. The battery
compartment should be grounded if made of metal. Failure
to follow this warning may result in death, personal injury or
property damage.
