order of the phases is not respected, the device will not operate.<br />
• In equipments with separate bypass line, an isolation transformer must be placed at any of<br />
both input power supply mains of the UPS (rectifier input or static bypass), in order to avoid the<br />
direct connection of the neutral of both mains through the internal wiring of the equipment..<br />
4-3-3. Connection of the output, terminals (X6 to X9)<br />
• As this is a device with class I protection against electric shocks, it is essential to install a<br />
protective earth conductor (connect earth (<br />
)).Connect the conductor to the terminal (X5),<br />
before connecting the power supply to the UPS input.<br />
• Connection to the output three phase:<br />
Connect the loads cables N-U-V-W to the output terminals (X9), (X6), (X7) and (X8), respecting<br />
the order of neutral and phases indicated on the label of the device and in this manual. If the<br />
order of the phases is not respected, the device will not operate.<br />
• Connection to the output single phase:<br />
Connect the loads cables U-N to the output terminals (X6) and (X9), respecting the order of<br />
phase and neutral indicated on the label of the device and in this manual. If the order of the<br />
phases is not respected, the device will not operate.<br />
4-3-4. Connection main protective earthing terminal ( )and protective earth<br />
bonding terminal ( )<br />
• As this is a device with class I protection against electric shocks, it is essential to install a<br />
protective earth conductor (connect earth (<br />
)Connect the conductor to the terminal (X5), before<br />
connecting the power supply to the UPS input.<br />
• Make sure that all the loads connected to the UPS are only connected to the protective earth bonding<br />
terminal ( )<br />
4-3-5. COM port relays. Connector (X32)<br />
The communications line (COM) constitutes a very low safety<br />
voltage circuit. To preserve the quality, it must be installed aside from other lines that have dangerous<br />
voltages (power distribution line).<br />
• The communication port to relays provides digital signals in the form of potential free contacts with<br />
a maximum applicable voltage and current of 6 A 30 V DC or 6 A 100 V AC. Both channels are in use
