7.You should have already removed the front panels of the battery units at the beginning of this Section 6.1. The corresponding access slot covers should also have been removed.
Now start to lay the battery wiring inside the UPS unit. Lay the insulated wire in the center downwards. Then carefully close the front cover of the UPS, lay the wire to the first external battery unit down through the slot you have removed the cover from. Also remember to secure the lock by tightening the two Philips screws located in the middle. Then push the UPS completely back into the rack and fasten the UPS on the side with the 4 M6x16 screws that come with it.
