The load can be transferred to the bypass line ifan overload occurs on the UPS output, for maintenance or in the event of amalfunction.ECO mode Operating mode by which the load is supplied directly by the AC source if it iswithin the tolerances defined by the user. This mode reduces the consumption ofelectrical power.Load Devices or systems connected to the UPS output.Manual bypass Rotary switch controlled by the user, used to connect the loads directly to theAC source.Transfer of the load to the manual bypass enables UPS maintenance withoutinterrupting the supply of power to the connected loads.Normal (double conversion) modeThe normal UPS operating mode in which the AC source supplies the UPS whichin turn supplies the connected loads (after electronic double conversion).Normal AC source Normal source of power for the UPS.Relay contacts Contacts supplying information to the user in the form of signals.UPS Uninterruptible Power Supply.The operating temperature is 0 to 40°C (8 hours at 45°C), however optimum operation is within the +20zto +25°C range.Battery backup time is adversely affected by high and low temperatures. It is significantly reduced atztemperatures under 10°C. Above 25°C, battery service life is cut in half every 10°C. Above 40°C, batterymanufacturers no longer guarantee operation due to the risk of thermal runaway.◗ Air enters through the front and exits through the back.Thermal characteristicsEX RT CLA moduleAC input voltage: 160-280 Volts AC,zInput frequency: 40-70 Hz,zBattery charge current: 6 A DC,zRecharge time to recover 90% of the rated backup time after discharge at full load:zConfiguration for2 hours backup timeConfiguration for4 hours backup timeConfiguration for8 hours backup timeEX RT 5 5 hours 12 hours 20 hoursEX RT 7 5 hours 12 hours 20 hoursEX RT 11 7 hours 15 hours 24 hours
