UPS battery replacement — ZRH
Power & cooling — ZRH
What is planned
The facility replaces the battery strings in one UPS module in ZRH. The module is taken out of the parallel set for the work; the remaining modules carry the full load with redundancy reduced by one. No machine loses power. Scheduled during the day so that the facility's electrical team is fully staffed.
