Connect Power Cables to the Power Bar
Prepare the power connection according to the cabling plans, see 14.1 Cable Plans.
Each column of cabinets is wired to one terminal in the Power bar.
Connect the conductors of the external power cables (L, N, PE) to the terminals in
the Power bar. See also Figure 59.
Prepare the data connection according to the cabling plans, see 14.1 Cable Plans.
Each column of cabinets needs one data input cable from the video controller.
