Electrical Installation
The electrical installation has to be done by qualified personnel. Follow all the Safety
Standards (CEI Standards in Italy or IEEE elsewhere) for the Input/Output connections
and for the right selection of Input/Output cables.
For safety we recommend using external circuit breaker between AC Mains line and
ATA Input line: the circuit breaker should be qualified as RCCB (Residual Current
Circuit Breaker RCCB) with leakage current protective function (leakage current < 300
mA).
For safety we recommend using external circuit breakers between ATA Output line
and the loads: the circuit breakers should be qualified as RCCB (Residual Current
Circuit Breaker RCCB) with leakage current protective function (leakage current < 30
mA).
It is also advisable to install a PV protection system between the PV panels line and the
PV panels Input of ATA, dimensioned according to the installed PV panels.
ATTENTION: for safety and efficiency it is recommended to use always cables with the
cross section equal or thicker than the specified one into the following table.
TECNOWARE declines any responsibility if these warnings are disregarded.
The ATA models have inside the case only the electronic parts: the batteries are installed externally.
Before starting the installation procedure, be sure that:
1. The AC Utility Line for the ATA has been removed, the PhotoVoltaic (PV) panels
and the batteries pack are disabled.
2. The ATA is completely OFF (only if graphic LCD panel is OFF).
Is necessary to apply a label, as the following one, into the AC input and output
distribution box.
