Construction Sequence and Methodology

Preparation before Installation

1. Ensure that Drawings for Installation are approved & coordinated with other services.
2. The material to be used must be inspected and approved.
3. Ensure that the material is free from damage before shifting to the areas of work. Any discrepancies, damages, etc., shall be reported for immediate further action.
4. Before starting the work, check that proper access to execute the works is in a suitable condition and free from obstruction.
5. Make sure that all health and safety measures and initiatives are in place.

Installation Procedure

1. UPS systems are to be installed as per the approved drawings, as per the new approved single-line diagram for UPS attached in the material submittal.
2. The installation will begin by placing the UPS units in the predetermined location. The input and output cables for each UPS will be connected.
3. Battery installation will be done by placing the battery cabinet in the pre-determined location and arranging the batteries on the cabinet such that 40 batteries will fit and are accessible for maintenance.
4. A Battery disconnection panel will also be installed near the battery racks in an accessible location as per the approved drawings. 
5. The battery set will be connected in series using flexible double insulation single core cables (provided along with UPS).
