1 Series 7400 Single Phase 1+N U PS 1.1 Introduction The Uninterruptible Power Supply system is connected between a critical load, such as digital drives & automation, distributed digital Process Control System, telecom equipment, programmable logic controller, mission critical applications , computer, and its three phase mains power supply.
2 Series 7400 Single Phase 1+N U PS As prev iously mentioned, each of the two modules forming the one - plus - one system is basically a standard single module 7400 series UPS. This section describes an individual module’s operating principles - the effects of the additional parallel control facilities on the standard module are described later.
3 Series 7400 Single Phase 1+N U PS The circuit block annotated ‘Static Switch’ in figure 2 contains an electronically controlled switching circuit, which enables the critical load to be connected either to the Inverter output or to a Bypass power source via the ‘static bypass line’.
4 Series 7400 Single Phase 1+N U PS Figure 2 illustrates what is known as the “ Split Bypass” config uration. This is the standard configuration for all 1PH Models In the “ Split Bypass ” conf.

7 Series 7400 Single Phase 1+N U PS When two of the standard 7400 modules just described are connected together to f orm a one - plus - one system, each module is fitted with an additional circuit board which allows the two modules to communicate with each other.
8 Series 7400 Single Phase 1+N U PS Battery charge current sharing: The illustration in figure 4 shows a dedicated battery installat ion for each module; however, it is possible to fit an option kit which allows the two modules in a one - plus - one system to share a common battery.
9 Series 7400 Single Phase 1+N U PS A “Common batt ery” option kit contains a DCCT (DC Current Transformers) which are fitted to the battery power lines and monitored by the parallel control logic. Each module monitors its battery charge current and compares it with the charge current provided by the other module.
10 Series 7400 Single Phase 1+N U PS The operator control panel is divided into three functional areas; ‘Mimic indications’, Control switches’ , and ‘LCD display panel’. Mimic Indications Six LEDs are mounted on a single line diagram to represent the variou s UPS power paths.
11 Series 7400 Single Phase 1+N U PS LS5 - Load on bypass: This led illuminates when the output isolator is closed and the load is connected to the bypass via the static switch. LS6 - Load on Inverter: This led illuminates when the output isolator is closed and the load is connected to the inverter via the static switch.
12 Series 7400 Single Phase 1+N U PS Switch S7 - Inverter ON: Pressing this switch activates the inverter and causes the load to be transferred to the inverter side of the static switch after the inverter voltage has had time to stabilise.
13 Series 7400 Single Phase 1+N U PS LCD Display An LCD display, capable of showing two rows of 40 c haracters, is used to indicate the UPS operating parameters, warnings and alarms. A DIP switch fitted to the display microprocessor board enables the displayed language to be easily selected to English, French, Italian, Spanish or German.
14 Series 7400 Single Phase 1+N U PS 1.3 Safety Precautions In common with other types of high power equipment, dangerous voltages are present within the UPS and battery enclosure. The risk of contact with these voltages is minimised as the live component parts are housed behind a hinged, lockable door.
15 Series 7400 Single Phase 1+N U PS 2.1 Introduction Starting and stopping the one - plus - one system is straightforward, however the modules’ response depends on whether it is configured as a Redundant or Non - Redundant system.
16 Series 7400 Single Phase 1+N U PS How to turn ON the System from a Shut down condition (Complete this actions on one module at a ti me) This procedure should be followed when turning on the one - plus - one system from a fully powered down condition - i.
17 Series 7400 Single Phase 1+N U PS How to turn ON the Sys tem from a Maint. power - down condition (Complete this action on module at a time) This procedure should be followed to start the one - plus - one from a MAINTENANCE power - down condition - i.
18 Series 7400 Single Phase 1+N U PS Mimic panel LEDs LS4 and LS6 should extinguish on both modules and LS5 should illuminate to show that the load has been transferred to the static bypass line.
19 Series 7400 Single Phase 1+N U PS IMPORTANT The Maintenance Bypass Isolator may be operated at any time when the UPS is powered down to connect / disconnect eac h load to the raw maintenance bypass supply if required. Emergency Stop The emergency stop pushbutton is located behind a hinged safety shield to prevent inadvertent operation.
20 Series 7400 Single Phase 1+N U PS.
21 Series 7400 Single Phase 1+N U PS 3.1 Introduction WARNING Do not apply electrical power to the UPS equipment before the arrival of the commissioning engineer WARNING The UPS equipment should be installed by a qualified engineer in accorda nce with the information contained in this chapter and the drawing package shipped inside the UPS cabinet.
22 Series 7400 Single Phase 1+N U PS The UPS cabinets can be moved by fork lift or crane. Fork lift apertures are provided in the sides of the base plate and are accessible after removing blanking covers fitted to the side panel ventilation grills. Roof - mounted eye - bolts are fitted to enable the cabinet to be crane - handled.
23 Series 7400 Single Phase 1+N U PS In 25kVA to 125 kVA module installations the batteries associated with the UPS equipment are usually contained in a purpose - built battery cabinet/ r ack which sits alongside the main UPS equipment. Sealed, maintenance - free batteries are normally used in this type of installation.
24 Series 7400 Single Phase 1+N U PS Note: If ‘side’ cable entry is to be used ensure that the blanking plates are removed before finally fixing the cabinet position. 5. All UPS models have a stabilising bar fitted to t he output transformer T1 and input choke L1 during shipment.
25 Series 7400 Single Phase 1+N U PS 3.3 Connecting UPS Power Cables WARNING Ø Before cabling - up the UPS, ensure that you are aware of the location an d operation of the external isolators that connect the UPS Input / Bypass supply to the mains distribution panel.
26 Series 7400 Single Phase 1+N U PS In the 25 - 40kVA UPS 1 PH models the input mains / bypass cables, UPS output cables and battery cables are connected to busbars located behind a safety cover just below the power isolator switches - as shown in figure 11.
27 Series 7400 Single Phase 1+N U PS 6. Co nnect the safety earth and any necessary bonding earth cables to the copper earth busbar located on the floor of the equipment below the power connections. Note: - The earthing and neutral bonding arrangement must be in accordance with local and national c odes of practice.
