We recommend that the terminal block covers, shown in Figure 2-6, should only be removed when wiring and unwiring the power shelf. The terminal block cover is slotted in such a way that cables can only come out the bottom portion of each cover.

The power supply terminal block lug opening width is 0.63 inch (1.6 cm). The terminal posts are centered 0.63 inches (5/8 inch) (1.6 cm) apart and are M6-threaded. We recommend that you use an appropriately sized 180-degree angle (straight) industry standard 2-hole, standard barrel compression lug, as shown in Figure 2-7, or an appropriately sized 45-degree angle industry standard 2-hole, standard barrel compression lug, as shown in Figure 2-8.
