Passport 15000, 20000 Hardware Installation, Maintenance, and Upgrade
Install a power-and-ground cable assembly to enable using power input
cables smaller than 1/0 AWG (53.5 mm
cables to feed the breaker interface panel (BIP).
• You must be familiar with "Safety considerations and best practices"
(page 53).
• You need a polyvalent power-and-ground assembly with part number
A0834143 or an ETSI power-and-ground assembly with part number
A0843149. The ETSI kit contains large green pan-head slotted machine
screws or 10-mm (3/8-in.) thread-forming hex-head screws for fastening
the frame ground cables.
• You need the following specialty tools:
— a medium Pozidriv screwdriver, for example a number 2 (do not
substitute a Phillips bit)
— 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
• You need a helper to hold the power-and-ground assembly until it is
fastened to the mounting apparatus.
• The terminal blocks on the assembly rail approximately align with the
pairs of battery and battery return studs at the rear of the BIP. Their
uneven spacing is normal.
1 At the rear of the BIP, unfasten any cables dressed along the horizontal
strain-relief bar. These are likely to be the red power output and alarm
cables from the BIP to other hardware parts. Leave the cables connected
at both ends.
2 Note the orientation of the strain-relief bar at the uprights and remove its
four 10-mm (3/8-in.) screws, as shown in the figure "The polyvalent
power-and-ground assembly A0834143" (page 493). Put the screws and
bar aside temporarily.
3 Hold the power-and-ground assembly in the air so that:
