6.1.- Connection to the mains.
6.1.1.- Connection to the mains of the NX or NX R version.
• The ground connection must necessarily be made, ensuring that this is done before connecting the voltage
to the input of the UPS.
• Connect the input pin (1), to the supply line and without the mains present (area contact open).
6.1.2.- Connection to the mains of the NX or NX R version, with the optional "Input polarity detector" (P).
• The input polarity detector only works on single-phase lines. If a single-phase unit with detector is connected
to a two-phase network, it will not be possible to start it.
• Connect the input plug (1) to an earthed power point, ensuring first of all that it has a network voltage or the
input polarity detector will not be able to verify if it has the right polarity and, consequently, the unit may not start.
- In UPS-700 NX to 1500 NX. The battery LED bar (d) should light up.
- In UPS-2000 NX to 3000 NX and in all rack-version models. Turn the magnetothermic input switch (5) «On» and
the battery LED bar (d) should light up according to the charge level of the batteries.
If, under these conditions, the line LED (a) lights up, it means that the network polarity in the plug (1) is correct.
If, on the other hand, it does not light up, this is a sign that the polarity is wrong. Disconnect the plug (1) from
the network power point, reverse the polarity and check that the LED (a) illuminates.
Note: With the correct input voltage and reversed polarity, by pressing the "On/Test" button (6), the unit will not
start.
6.2.- Connection of the output (Connection to the loads to be supplied).
• Connect the loads to the output bases (2).
• Never connect scanners, laser printers, plotters or any other of high power consuming equipment to the
output sockets (2) as they can overload the equipment.
6.3.- Connecting to external batteries, connector (4).
• All NX series UPS have a connector (4) to optionally increase autonomy by connecting one or more additional
battery modules to the unit. This must only be done in versions with extended autonomy.
Before interconnecting the UPS with the battery module/s, make sure the unit is switched off and the battery
module protection is "OFF". Then connect one end of the cable harness supplied to connector (4) and the other
end to the terminals of the battery module, always respecting the polarity indicated on the labeling and the color
of the cables (red – positive and black - negative).
