Vertiv Liebert MBX, Инструкция по установке и эксплуатации, Страница: 23 / 34

5 MAINTENANCE
The design of the Liebert® MBX Busway System lends itself to simple, reliable installation that enables
future modifications to be carried out easily. It has no defined routine maintenance requirements. Any
maintenance that may be required is easily identified by thermal imaging of the run.
Standard electrical troubleshooting procedures should be used to isolate problems in the unit. Repair or
replacement of standard items, such as circuit breakers and fuses can either be handled by qualified
electricians or referred to Vertiv™. Repairs related to the monitoring system should be referred to Vertiv.
See
Technical Support on page 25 for contact information.
Annual general system inspections, cleaning and operation checks are recommended to ensure system
performance and long service life.
5.1 Tap-Off Box Maintenance
As with the main busway track, the Joint Packs require checking on the tap-off connections and thermal
imaging can identify localized hot spots.
Upon identifying a local problem, preventive maintenance should be investigated with the busway track
isolated.
• Visually check the installation of the Tap-Off Box.
• Check outgoing cable connections.
• Check the operation of the switching On/Off operation.
• Examine protective device for signs of short circuit operation. If a short circuit has occurred on the
equipment connected to the Tap-Off Module, check operation of device and the integrity of the
device.
