UPS Planning an installation

The decision making process of selecting an Uninterruptible Power System ( UPS) becomes more complex as the UPS increases in capacity and battery support time. The following provides a simple check list of the items which should be considered:

UPS selection and ordering

Before ordering the UPS it is always worthwhile to ensure that the calculated load in VA and Watts (W) can be supported by the UPS. Advance recommend that a UPS is always sized to allow for a 25% increase in load expansion.

Further considerations should be applied to UPS installations with long battery support times. In such instances it may be necessary to up rate the UPS charger or add extra chargers to maintain a reasonable battery recharge time. A choice between 5 year and 10 year design life batteries may also be available. Every effort is made to ensure that UPS deliveries are to customer agreed delivery dates. However the dynamic nature of the business and the length of time that can elapse between quotation and order placement means that users should always check on the current lead time prior to order.

UPS environment

A UPS generates heat and noise. This varies with the UPS technology employed.

In confined areas and/or areas where air conditioning is employed customers should assess the impact of the UPS on current ambient temperatures. High ambient temperatures reduce battery design life. High humidity can cause component corrosion and reduce design life. Extra ventilation or increased air conditioning may be required. The noise level generated by the UPS is always relative to the environment. In confined populated areas it may be necessary to consider siting the UPS in a separate room or installing a low noise generating UPS technology. A UPS normally uses fans to provide cooling to the internal components within the UPS. In rooms without sealed floors or dusty industrial environments dust may be drawn into the UPS by the internal fans. This can cause the fans to fail early. In such environments it may be necessary to either 'cure’ the floor or install dust filters on the UPS air intakes.

In environments where safety sprinkler systems are fitted it is recommended that the UPS is not sited near the sprinklers and/or that drip trays are fitted above the UPS.

Maintenance plans

A UPS represents a significant investment for any organisation. It should be adequately maintained and supported to ensure it continues to provide stable and secure operation. Advance offers a range of extended warranties and maintenance plans.
