• You must be familiar with "Safety considerations and best practices"
(page 53).
• You need an installed BIP with PEC NT6C61 or NT6C62 for a
Passport 15000, or AP6C67 or AP6C68 for a Passport 20000.
• You need the following specialty tools:
— a cutter for up to 1/0 AWG (53.5 mm
— a crimper for lugs up 1/0 AWG (53.5 mm
cable feeding the BIP
— a medium Pozidriv screwdriver, for example a number 2 (do not
substitute a Phillips) for the insulation boot clamp
— an 11-mm (7/16-in.) deep socket with a properly calibrated torque
wrench capable of 6.5 Nm (57.5 in.-lbs) and a 20-cm (8-in.)
extender for the lug nuts
• When the feed cables are any size less than 1/0 AWG (53.5 mm
must either provide 90-degree offset 2-hole lugs that fit under the
insulation boots on the BIP and match the cable size, or use an optional
power-and-ground cable assembly.
Procedure steps
1 At the front of the BIP, ensure that all breakers are switched off (the O is
pressed in).
2 At the rear of the BIP, locate the stud for the B1+ connection as identified
in the figure "Overhead power input cables for the lower shelf connected

CAUTION
Risk of damage to power connections by weight
Use tie-wraps every 10 cm (4 in.) to fasten the cables to
the 7-mm (0.25-in.) thick strain-relief bracket (part
number P0891284 or P0911981) at the rear of the BIP. Use
tie-wraps every 15 cm (6 in.) to fasten the cables to the
cable ladder from an overhead cable trough or down the
side of the NEBS 2000 frame or equivalent. Fastening the
power cables provides strain relief from the weight of the
cables on the power input lugs at the rear of the BIP.
