Disconnecting Power Input Cables From The Bip - Nortel Passport 15000 Hardware Installation And Maintenance

Disconnecting power input cables from the BIP

Prerequisites
Passport 15000, 20000 Hardware Installation, Maintenance, and Upgrade
Disconnect power input cables from the BIP to enable removing the BIP for
an upgrade or a replacement due to failure, or to enable replacing the cable.
WARNING
Risk of injury by electrocution
Each power input feed to a breaker interface module
(BIM) is rated up to 100 A. All breakers on the BIMs must
be switched off (the O is pressed in) and power to the BIP
must be switched off to the BIP.
WARNUNG
Gefahr durch elektrischen Schlag
Alle Speisestromzuführungen am
Trennschalterkopplungsmodul (BIM) sind auf 100 A
ausgelegt. Alle Trennschalter an den BIMs müssen
ausgeschaltet sein (O ist gedrückt) und die
Stromversorgung zum BIP muß getrennt sein.
WARNING
Risk of injury or damage by electricity
When switching off power breakers on a breaker interface
module (BIM) or in the circuit up to it, or removing a fuse
from the circuit up to it, always put tape over the breaker
or fuse cavity. The tape indicates it was manually switched
off, and not tripped by the system. This prevents
accidental activation of the power circuit, especially when
power cables are being handled.
