3.7.1Battery Circuit Breaker "QF1" Connection
Connect the cable from connector XR3 (pins 2 to 8) on the "Media Contacts 11" board in the UPS cabinet to connector XR1 in the battery cabinet containing battery circuit breaker QF1.
IMPORTANT | In the case of a complex installation with parallel units, there should be only one |
| emergency shutdown pushbutton and this pushbutton must interrupt all the units. |
| This pushbutton must therefore have as many contacts as there are units in the |
| installation. The emergency shutdown pushbutton turns off the rectifier/ chargers |
| and inverters, opens the battery circuit breakers (QF1), the input circuit breaker (Q1) |
| on the normal source, the backfeed protection contactor (K4S) on the bypass AC |
| source, blocks the static switches and activates a contact on the "Media Contacts 11" |
| board (terminals 1 to 3 on connector XR4). |
