Series 7400 Single Phase 1+N UPS

3.1.3 Battery Location

In 25kVA to 125 kVA module installations the batteries associated with the UPS equipment are usually contained in a purpose-built battery cabinet/ rack which sits alongside the main UPS equipment. Sealed, maintenance-free batteries are normally used in this type of installation.

Due to their increased capacity, the batteries associated with larger UPS installations are usually too big to be mounted in a single cabinet and are either rack mounted or fitted in multiple, or bespoke, battery cabinets. Such installations may utilise non- sealed lead acid cells, requiring regular attention and impose their own environmental requirements.

Pedestals are required for the battery cabinets when they are located on raised floors, in the same way as for the UPS cabinets.

Where battery racks are used, they should be sited and assembled in accordance with the battery manufacturer’s recommendations. In general, batteries require a well ventilated, clean and dry environment at reasonable temperatures to obtain efficient battery operation.

Battery manufacturers’ literature provide detailed safety measures to be observed when employing large battery banks and these should be studied and the proposed battery installation checked to verify compliance with the appropriate recommendations.

The batteries are connected to the UPS through a circuit breaker which is manually closed and electronically tripped via the UPS control circuitry. If the batteries are cabinet-mounted this circuit breaker is fitted within the cabinet; however, if the batteries are rack-mounted or otherwise located remote to the main UPS cabinet then the battery circuit breaker must be mounted as near as possible to the batteries themselves, and the power and control cables connected to the UPS using the most direct route possible. Emerson Network Power (India) Pvt. Ltd. offer a purpose-designed remote battery circuit breaker box, containing the circuit breaker and its necessary control board, as a standard option kit.

3.2 Preliminary Checks

Before you install the UPS hardware you should carry out the following preliminary checks:

1.Verify that the UPS room satisfies the environmental conditions stipulated in the equipment specification, paying particular attention to the ambient temperature and air exchange system.

2.Remove any packaging devices debris then visually examine the UPS and battery equipment for transit damage, both internally and externally. Report any such damage to the shipper immediately.

3.Verify that the shipment is complete -e.g. that the battery

contains the correct number of cells etc. Report any discrepancy immediately.

4.When you are satisfied that the equipment is complete and in good condition move it to its proposed final position.
