The UPS systems commissioning test and inspection procedures are to conform to; <\/p>\n
\u2022 BS EN 50091-1:1993 – Specification for Uninterruptible Power Supplies (UPS). General and Safety Requirements, AND <\/p>\n
\u2022 IEC 62040-3 (Draft Edition \u2013 2) in particular the Efficiency test procedures outlined in its “Annexure-J”. <\/p>\n
These procedures to include: <\/p>\n
1. Visual Inspection:
\na. Visually inspect all equipment for signs of damage or foreign materials.
\nb. Observe the type of ventilation, the cleanliness of the room, the use of proper signs, and any other safety related factors. <\/p>\n
2. Mechanical Inspection:
\na. Check all the power connections for tightness.
\nb. Check all the control wiring terminations and plugs for tightness or proper seating. <\/p>\n
3. Electrical Pre-check:
\na. Check the DC bus for a possible short circuit.
\nb. Check input and Bypass power for proper voltages and phase rotation.
\nc. Check all lamp test functions. <\/p>\n
4. Initial UPS Startup:
\na. Verify that all the alarms are in a “go” condition.
\nb. Energize the UPS module and verify the proper DC, walkup, and AC phase on.
\nc. Check the DC link holding voltage, AC output voltages, and output waveforms.
\nd. Check the final DC link voltage and Inverter AC output. Adjust if required.
\ne. Check for the proper synchronization.
\nf. Check for the voltage difference between the Inverter output and the Bypass source.
\ng. Perform full-load, step-load, and battery discharge tests using supplier furnished load bank.<\/p>\n","protected":false},"excerpt":{"rendered":"
