h2 Fit the KRL-B522L Into the Airport Indoor Room
The KRL-B522L measures approximately 2,480 mm long, 1,400 mm deep, and 2,050 mm high, with an approximate weight of 4,900 kg. The indoor electrical-room design needs to accommodate this cabinet, the 180 kVA UPS lineup, bypass equipment, and protected-load panels in one serviceable arrangement. The cabinet is vertical; KRL should confirm the detailed modular configuration, service side, and final cable-entry layout for the offered configuration.
- Show the cabinet footprint, front and rear service access, and the UPS/bypass service zone on the general arrangement drawing.
- Confirm delivery route, door width, corridor turns, lifting plan, floor load and plinth design for the 4,900 kg cabinet.
- Define cooling air path, room HVAC duty, detection, fire-protection equipment and emergency-stop locations.
- Show cable tray routes, power-cable separation, earthing conductors, bypass conductors and monitoring cabling.
- Keep the critical-power room under controlled technical access with equipment labels and operational signage.
KRL's public B522L data identifies liquid cooling, an IP65 battery enclosure, PCS smart cooling, and a fire-protection system. The public page does not state airport electrical-room clearance requirements, room heat-rejection figures, or a South African installation drawing. Those items belong in the project-specific engineering deliverables. Use KRL's Inkqubo yoyilo yokugcinwa kwamandla orhwebo to connect the product dimensions with the final layout, protection plan, and commissioning sequence.
h2 Put SABS Evidence, Drawings and Product Photographs in the Delivery Scope
SABS compliance evidence is an explicit customer requirement. The public KRL-B522L product page does not list an SABS certificate. The commercial proposal therefore needs a compliance register that ties every certificate, report and drawing to the exact battery cabinet, PCS, online UPS, bypass equipment and enclosure delivered to the airport.
| Required delivery item | Airport buyer uses it to verify | Acceptance condition |
|---|---|---|
| SABS evidence register | Certificate scope, model identity, applicable standard and validity | Every document matches the final bill of materials |

The product-photo pack should include front, side, rear, and service views, together with KRL model-identification details, cable-entry direction, cooling equipment, fire-protection interfaces, nameplate format, packaging, and loading method. That evidence lets the EPC compare the final layout against the physical cabinet before dispatch.
h2 Write the One-Year Warranty Around the Entire Critical-Power System
The requested one-year warranty must extend to all supplied components in the airport package. The warranty matrix must assign responsibility for the UPS, bypass, control, and commissioning interfaces. Place every item in one matrix and give the airport a single escalation path.

| Controls and communications | Alarm mapping, point list, protocol gateway and access configuration | Point-to-point communication test record |
| Commissioning and service response | Functional tests, training, fault notification, diagnosis and corrective-action route | Signed acceptance, training and escalation records |
The warranty schedule should state its start date, approved operating conditions, capacity-test method, response-time commitment, parts route, travel responsibility, alarm-data access, and escalation contacts. KRL's Isikhokelo sokukhetha ugcino-amandla lwezorhwebo can support the final comparison of warranty boundary, runtime commitment, site layout, and system responsibility.
h2 Commission the Airport Package Against Measured Results
The commissioning team should test the actual airport load or a documented equivalent load bank. The test record needs to show 400 Vac operating data, current, kW, kVA, power factor, UPS output quality, BESS operating state, bypass function, alarms, generator sequence, and completed backup duration. A signed handover package establishes the offered system as an operating asset with traceable responsibility.
- Signed one-line diagram and final general arrangement drawing.
