Power Cable Specifications With A Polyvalent Assembly - Nortel Passport 15000 Preparation Manual

Note: The polyvalent or ETSI power-and-ground assembly
accommodates non-Super Flex power input cables from No. 6 AWG
(13.3 mm
codes accept the equipment, using the assembly to accommodate power
input cabling at the BIP can be a much simpler installation method at
your site. See "Power cable specifications with a polyvalent assembly"
(page 147) or "Power cable specifications with an ETSI assembly"
(page 149).
If, according to the National Electrical Code (NEC), less than 100 A
protectors are being used between the site power source and the BIP, and the
room's ambient temperature can reach 50 degrees Celsius (122 degrees
Fahrenheit), a cluster of 8 power conductors running over 2 feet with a cable
insulation rating of 90 degrees Celsius (194 degrees Fahrenheit) is required.
These specifications must be met by whatever cable you plan to install.
All power cables must meet the requirements of the country of installation.
For example, use cable with a rating such as CSA or UL VW-1. For the
ratings, see the table "North American ratings for cable" (page 145).
Additional information about cables used in a setup with an ac rectifier is
included in "Power cable specifications when using ac rectifiers" (page 152).
Power cable specifications with a polyvalent assembly
When the power-and-ground setup of a Passport 15000 or 20000 uses the
optional polyvalent assembly, the assembly is installed between the power
source cables and the breaker interface panel (BIP). See the figure
"Polyvalent power-and-ground assembly A0834143" (page 149).

CAUTION
Risk of damage to equipment by reversed polarity
Use the plus (+) and minus (-) symbols on the rear of the
breaker interface panel (BIP) to ensure that the polarity of
each A and B battery (-48/-60 V dc) and battery return for
the input power feeds is correct. When powering up the
BIP, reversed polarity will damage circuits inside it.
