• You need an installed polyvalent power-and-ground assembly with part
number A0834143 or an ETSI power-and-ground assembly with part
number A0843149.
• You need power input cables rated to the hardware configuration of the
Passport 15000 or 20000.
• You need a cutter for up to 1/0 AWG (53.5 mm
2
) cable.
• Grounding the assembly is provided when the NEBS 2000 frame is
cabled to the site ground window.
Procedure steps
1 At the front of the BIP, ensure that all breakers are switched off (the O is
pressed in).
2 Near the rear of the BIP, locate the power input cable labelled A1+. All of
the power input cables should have been labelled according to the figure
“Overhead power input cables for the lower shelf connected to the BIP”
(page 337).
3 Route the cable up to the terminal block that aligns with the appropriate
BIP connection, and dress the cable above for permanent suspension.
Refer to the figures
• “Power input cables connected to a polyvalent power-and-ground
assembly A0834143” (page 310)
• “The ETSI power-and-ground assembly A0834149” (page 311)
4 Cut the cable so that it can be stripped to fit into the block and hang
unstressed but not sagging.
5 Strip 2.5 cm (1 in.) of insulation from the end of the cable.
6 On the rear of the BIP, locate the right cable from the rightmost pair of
studs. It has a + sign beside it.
7 Trace the cable from the BIP to the bottom of the terminal block. Note
which side of the block that the cable connects to.
8 Locate the screw hole on the side of the noted block facing you, unfasten
it, and put it aside momentarily. If complete removal is resisted, unfasten
the screw as far as it will go without forcing it.
9 Insert the end of the cable into the top opening in the block so that:
• the cable aligns with the traced bottom cable
