UPS

E&C’s products come with a standard warranty of 12 Months from the date of installation or 14 months from the date of dispatch, whichever is earlier. Warranty covers all defects encountered during the normal operation.

Any failures of the UPS due to abnormal or improper use of the equipment other than its intended use are not covered under warranty.

Site requirements should be as mentioned in the site requirements document. Our Service engineer will inspect and verify the site readiness and suitability prior to installation of the UPS. Any deficiencies in the site should be rectified for unhindered and defect free operation.

Exposure to direct sunlight, rain, water logging, contamination and dust prone area will reduce the life of the UPS and cause premature and sudden failures. Warranty will cease if the equipment is installed under such conditions.

Batteries

Warranty on Batteries applies to failures of the battery due to manufacturing defects. Normally the manufacturing defects in batteries will surface within the first two months from installation. The batteries will be checked by the service team of the Battery Manufacturer for appropriate action.

Warranty on Batteries will be as per the Battery Manufacturers. The warranty on batteries is normally 12 months from the date of installation or 14 months from the date of dispatch.

Note on Batteries:
Batteries are used as stores of electrical energy providing the means of backup support when the power outage occurs.

To derive the optimal benefits of installing a UPS, the UPS and the batteries should be installed and maintained in a clean atmosphere. The condition of the batteries is very important as it is key to delivering the backup power for the expected duration.

The life of the batteries depends on the following important factors:

1.       Charging Current

2.       Time between subsequent discharges (or) the charging time

3.       Ambient temperature

The batteries need sufficient charging time which is normally 8-9 hours at charging levels of current as suggested by Battery Manufacturers. If the batteries do not get charged fully before the next power outage occurs, then the life of the batteries gets reduced.

The charging current is one of the very important factors which determine the life of the batteries. Battery manufacturers’ guidelines recommend a charging current which is between 0.1C to 0.2C.

  • Lower than recommended charging currents lead to very long charging time. Abnormally long charging currents leads to sulphation of the lead plates and reduces the capability of the lead plates in delivering the power.
  • Higher than the recommended charging currents lead to generation of gases inside the batteries and leads to bulging of batteries leading to permanent failure.
  • Batteries left uncharged for prolonged periods of time deteriorate the batteries faster leading to permanent failure.

The higher the ambient temperature of the surrounding area, the lower will be the life of the batteries. Battery manufacturers recommend 25-30 degrees Celsius.

The life of the batteries is also measured in terms of Discharge / Charge cycles. The more the frequent power cuts and the longer the power cuts, the faster will be the degradation of the life of batteries.
