The ETSI hardware must be installed on the NEBS 2000 frame on site as an
optional kit (part number A0834149). All of the criteria in "Power
architecture" (page 120) still apply.
The power cables in the ETSI hardware kit that connect the bottom of the
terminal blocks to the BIP studs are provided. The difference with ETSI
power cables is that the power cable for this leg is size 1/0 AWG (53.49 mm
Super Flex excelene (manufactured by Essex). The cable is rated R +105C
600 V 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.
Before installing the ETSI power-and-ground 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. The ground cables in the ETSI hardware kit that
connect each middle terminal block to the grounding strip across the top rear
of the NEBS 2000 frame are also provided. Typically, the grounding cable is
2
6 AWG (13.3 mm ) with a matched straight 2-hole lug.
Note: The ETSI power and ground assembly can accommodate power
input cables from No. 6 AWG (13.3 mm
including non-Super Flex.
