EXTERNAL PROTECTION
Protections for Alternating Current side
Leonardo Off-Grid 4kW/5000/48 GE is equipped with an AC-OUT alternating current output line and an AC-IN
alternating current input line.
Since the device has a conductor connected to the NEUTRAL - TT system, the AC output line AC-OUT can be protected
with a thermal-magnetic circuit breaker AC type, with nominal current In = 32A and differential current Id = 0.03 (usually
this switch is already in the house switchboard as protection against indirect contact, with 30mA of differential current).
The input line into alternating current AC-IN can be protected with a thermal-magnetic circuit breaker AC type, with
nominal current In = 32A and differential current Id = 0.3A, this switch can be put in an additional general switchboard
or, if possible, in the existing switchboard of the house.
Protections Direct Current side
The battery bank is connected through a protective fuse to the positive pole, and the positive pole disconnection switch
ensures that the inverter is activated in complete safety.
ATTENTION: the battery fuse mounting accessories are designed for batteries that have fixing clamps with M8 bolts,
in the case of different diameter of the fixing bolt it will not be possible to use the accessories supplied. If a different
type of fuse is used, it must be sized correctly, otherwise the system may be impaired.
Pic.5 Protection Fuse
INVERTER CIRCUIT BREAKER
The activation of the positive pole of the cutting switch provides the power of the inverter in complete safety.
ATTENTION: in the device ON sequence the circuit breaker
must be activated ON for FIRST, with respect to the PV
connections and AC-IN and AC-OUT alternating current.
In the device OFF sequence of the device, the circuit breaker
must be deactivated on OFF for LAST, compared to the PV
connections and AC-IN and AC-OUT alternating current.
