UPS Systems procurement guide
UPS systems maintain supply to sensitive equipment during outages and disturbances. Rating and runtime are matched to the connected critical load. Electrical equipment must be selected as part of a system, using load, network, protection, environment and applicable project requirements.
System role and load
The stated applications are Data centres and server rooms, Medical and laboratory equipment, Control and instrumentation systems and Office and communications equipment. Provide the system role, connected loads, duty, redundancy, future capacity and interfaces with existing equipment.
Ratings, compatibility and acceptance
Compare proposals against Critical load in kVA, Required runtime on battery, Single or three phase supply, Topology required and Installation space and ventilation. Require source-specific drawings, datasheets, protection or coordination information and the test/standard evidence called for by the project.
Installation, protection and support
Confirm enclosure and environmental conditions, cable/termination interfaces, dimensions and weights, transport protection, site access, installation boundaries, testing, commissioning, training, warranty expectations and spare components.
Information to include in your quotation request
Send the single-line diagram or system description, load and duty, Critical load in kVA, Required runtime on battery, Single or three phase supply, Topology required and Installation space and ventilation, quantity, site conditions, existing interfaces, destination, installation/testing scope and required project documents.
