Connecting A Power Input Cable To A Terminal Block - Nortel Passport 15000 Hardware Installation And Maintenance

Connecting a power input cable to a terminal block

Prerequisites
Passport 15000, 20000 Hardware Installation, Maintenance, and Upgrade
Connect a power input cable to a terminal block of a polyvalent or ETSI
power-and-ground assembly to provide power to the assembly which feeds
the breaker interface panel (BIP).
WARNING
Risk of injury or equipment damage by electricity
When connecting power input cables at the BIP, ensure
that the source of power at the other ends of the cables
(feeds) is off (disconnected), fuses are removed, or the
breakers are off). Also ensure that all BIP breakers are off
(the O is pressed in).
WARNUNG
Verletzungsgefahr oder Geräteschäden durch
Elektrizität
Vergewissern Sie sich beim Verbinden der Netzkabel am
Trennschalterkopplungsmodul (BIP), daß die
Stromversorgung an den anderen Kabelenden
(Speisestromzuführungen) getrennt ist oder daß die
Sicherungen entfernt bzw. die Trennschalter ausgeschaltet
sind. Stellen Sie außerdem sicher, daß alle BIP-
Trennschalter ausgeschaltet sind (O ist gedrückt).
CAUTION
Risk of equipment damage 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.
• You must be familiar with "Safety considerations and best practices"
(page 53).
