The polyvalent hardware must be installed on the NEBS 2000 frame on site
as an optional kit (part number A0834143). All of the criteria in "Power
architecture" (page 120) still apply.
The power cables in the polyvalent hardware kit that connect the bottom of
the terminal blocks to the BIP studs are provided. The difference with
polyvalent power cables is that the power cable for this leg is size 2/0 AWG
2
(67.43 mm ) Super Flex excelene (manufactured by Essex). The cable is rated
R +105C 600V and is cut to measure at 21 cm (8.3 inches). The narrow-
tongued 2-hole 90-degree offset 2 AWG lugs used to fasten the power cables
to the BIP are included.
When connecting the power input cables to the terminal blocks, bared cable
is fastened directly to each block, therefore no special lugs are required.
Note: The polyvalent power-and-ground assembly can accommodate
power input cables from No. 6 AWG (13.3 mm
2
(33.62 mm ), including non-Super Flex.
The NEBS 2000 frame is normally grounded to the site window through the
the silvery grounding strip at the top of the frame. The polyvalent assembly
bracket covers the strip. When using the polyvalent assembly, the grounding
point between the frame and the site ground window must be on the silvery
strip at the top front of the frame.
