Make sure to press the connectors quickly and firmly into one another (red in red, black in black). If you see a small electric arc while doing this, this is no cause
for concern.
If you use external battery extensions in combination with the UPS, proceed as described in Chapter 6.1.2. Otherwise, close the front panel again slowly and carefully following the directions in reversed order. Make sure that you do not pinch any wires. As the last step, don’t forget to lock the front panel into place using the two screws located in the middle. Then push the UPS completely back into the rack and fasten the UPS on the side using the 4 M6x16 screws that come with it. Continue with Chapter 6.2 on pg. 36ff.
