Mains connection
The connection to the mains must be carried out with protection fuses between the
mains and the UPS.
The use of differential protection devices in the line supplying the UPS is
unadvisable. The leakage current to ground due to the RFI filters is rather high
and it can cause spurious tripping of the protection device.
According to CEI EN62040-1 standard, in order to take into account the UPS’
leakage current, residual current devices having adjustable threshold can be used.
4.1
CONNECTING THE POWER CABLES
For the electric connection of the
UPSaver
UPS, connect the following cables:
DC supply from the battery (
+B
,
-B
,
N
);
AC supply from the rectifier supply mains (
1-L1
,
1-L2
,
1-L3)
;
Neutral conductors of the input lines (
1-N
,
2-N)
AC supply from the bypass supply mains (
2-L1
,
2-L2
,
2-L3)
;
AC output to the loads (
3-L1
,
3-L2
,
3-L3
,
3-N)
.
Injury hazard due to electric shock!
Very high voltages are present at the ends of the cables coming from the battery:
Isolate the battery via DC circuit breakers before connecting it to the UPS;
Connect the ground cable to the relevant bar before carrying out any other
connection inside the device.
Risk of damages to the device due to insufficient insulation
The cables must be protected from short-circuits and leakage currents to earth;
The connection points must be hermetically sealed to prevent the air from
being sucked through the cable passage.
Risk of damages to the device due to incorrect wiring
To connect the device, follow the electrical drawing scrupulously and respect the
polarity of cables.
