*Caution:
When installing this system in high humidity
locations, install using ground fault equipment
breakers (often referred to in other countries
as an ELCB earth leakage current breaker) to
reduce the risk of leaking current which may
result in electric shock or potential fire. We
suggest installing GFEB breakers or follow
local electrical code. This system uses an
inverter, which means that when used with a
ground fault breaker you must use breakers
that can handle higher harmonics such as a
(GFEB) Ground Fault Equipment Breaker
(30 mA or greater) in order to prevent
malfunctioning of ground fault device.
