  • Crane
  • Fork Lift
  • Hammer and screw driver
  • Laptop computer
  • Approved test equipment
  • Correctly rated load and cables



7.1 Receipt and Storage of Material :

  • The materials shall be offloaded in designated location (in weather proof place) in original packing as far as possible.
  • The permissible storage temperature shall be ensured to maintain as mentioned in the instruction manual
  • It shall be ensured that protection of UPS against damage

7.2 Installation Procedures of UPS

7.2.1 Before installation, the concerned area shall be clean and free from dust.

7.2.2 By using the crane, the pallets containing battery & UPS shall be removed from the truck and it will be placed temporarily in the corridor as close to UPS room as possible in order to avoid unnecessary ways.

7.2.3 Ropes shall be attached far enough on the hoisting tackle so that they cannot exert any forces on UPS.

7.2.4 The ropes shall be slung around the ends of the wooden pallet.

7.2.5 It shall be ensured that nobody is standing in the swinging area of lifted UPS.

7.2.6 Unload the transport units in packed condition and leave packed as long as possible.

7.2.7 After unloading all pallets in the temporary place, each pallet shall be dismantled carefully to take the subject materials out.

7.2.8 Using fork lift, UPS and Battery shall be moved to the place of installation in the Telecom room.

7.2.9 While moving through corridor and inside the room, it shall be ensured that  materials  should  not  hit the  side  walls  and  other  panels  already installed in the room.

7.2.10 While positioning the Battery and UPS, it shall be ensured  that clearance  between them and from the wall is as per approved  drawing.

7.3 Installation Check

7.3.1 It is to  be  ensured  for  proper  tightening  all  external  connections  to UPS, battery  and load.

7.3.2 It is to be ensured for proper phase rotation of AC and polarity of DC connections.

7.3.3 All protective earth connections are to be checked.

7.3.4 Service switch installation is to be checked.

7.4 Inspection

7.4.1 Mechanical Inspection

General inspection of external steel work & internal components :   Physical damage internal or external.   UPS and cabinets lined up.   Doors fixed properly.

7.4.2 Electrical Inspection   The size of power cable for UPS input, output, bypass and battery cabinets.   Voltage measurement for UPS input ,output, Bypass

7.5 Testing Procedure (Load Bank Test)

7.5.1 Barriers / signs shall be erected if necessary to ensure personnel approaching the work area are adequately informed of the operation in progress.

7.5.2 The cables of sufficient size shall be run to support the load bank.

7.5.3 The final connection to the UPS shall be made at the output point once it has been established that it is DEAD and safe to do so.

7.5.4 The load bank shall be energized with zero loads and checked for functionality If   satisfactory the UPS shall be energized and switched to support the load bank.

7.5.5 Load shall be applied to the kW rating of the UPS (assuming unity power factor load bank) and the UPS allowed running for 15 minutes.

7.5.6 On starting the battery discharge test the mains shall be failed at the closest isolation point upstream of the UPS to simulate mains failure. Battery voltage and current will be recorded from the UPS display at 60-second intervals until cut-off voltage is achieved.

7.5.7 The mains supply shall be re-installed and the UPS allowed restarting, Recharge voltage and current shall be recorded and the battery allowed recharging.

7.5.8 Before disconnecting the load bank it shall be allowed to cool off load and then switched off. The output of the UPS  will be isolated to allow the load bank to be disconnected.

7.5.9 On completion of the load bank test all connections, power and control, shall be remade and checked.   If the battery still requires re-charging the UPS shall be started and left to recharge either supplying the load or isolated from it   The load bank shall be packed for removal and stored safely until dispatched.   All barriers / signs removed leaving the workplace as it was found   Results shall be drawn up into a report and completion certificate issued

7.6 Safety Equipment

All necessary PPE and safety gear shall be worn at all times during the execution of work, In full compliance with safety requirements.

7.6.1    Helmets

7.6.2    Safety Shoes

7.6.3    Hand gloves

7.6.4    Safety signs

7.6.5    Reflective Vest

7.7 Safety Checks

Safety checks will be made prior to commencement of work in order to ensure that materials and equipment  are in safe working order in accordance with project and site regulations.
