Summary:

On Tuesday December 4th between 5.00h and 7.00h we will perform a blackbuilding emergency power test.

Details:

During this maintenance we will switch off our power supply for the entire location BIT-1 for 60 minutes to test our emergency power systems. During this test, engineers from BIT will be monitoring the test on multiple locations and will, if the need should arise, intervene. As described in the RFO that was published after the incident during the last blackbuilding emergency power test we will perform a battery discharge test in the days leading up to the blackbuilding test. This discharge test will be performed on both feeds, one after the other. The battery monitoring system that was mentioned in the same RFO is operational. This system enables us to have a continuous view on the state of each individual battery.
