Connecting power output cables to a system of ac rectifiers
Connect dc power output cables to a system of ac rectifiers to provide the
source of power to the breaker interface panel (BIP) of a Passport 15000 or
20000.
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• The power input cables from the BIP must already have been installed
and labelled up to the system of ac rectifiers.
• The system of ac rectifiers must already be installed according to the
product’s own hardware instructions. When the system of ac rectifiers is
an Astec MFA150, follow the installation instructions in the Astec
document 167-9021-133 Advanced Power Systems MFA150 Modular
Front Access Power System Detailed Installation Guidelines and
Procedures Manual. The power and alarm cabling between the MFA150
and the BIP is covered in this document.
• When the system is an MFA150, you need cable kit AP5C90FJ, which
includes
— 100 m (328 ft) of No. 2 AWG (33.62 mm
2
) cable, to be cut equally
for the input cables
— for the MFA150, five 1-hole 2 AWG lugs and six 2-hole 5/8-in. lugs
• Any system of ac rectifiers must be grounded to the same ground window
as the Passport 15000 or 20000. When using an MFA150 power system
of ac rectifiers, follow the ac power requirements for the rectifiers and the
system grounding procedure in the Astec document 167-9021-133
Advanced Power Systems MFA150 Modular Front Access Power
System Detailed Installation Guidelines and Procedures Manual.
• The MFA150 rectifier shelves are labelled A and B at the front of the
hardware setup. These designations have no relationship to individual
circuit breakers on the controller or to the A and B power feeds
connecting the MFA150 to a Passport 15000 or 20000.
