Removing a BIM

Prerequisites
Procedure steps
241-1501-240 5.2S2
Remove a BIM to replace it due to a failure or to enable safer removal of the
BIP.
WARNING
Risk of injury by electrocution
Each power input feed to a breaker interface module
(BIM) is rated up to 100 A. Prior to removing a BIM,
power to the BIM must be switched off for the last leg of
site power up to the BIM, and all breakers on the BIM
must be switched off (the O is pressed in).
WARNUNG
Lebensgefahr
Die Speisestromzuführungen zu jedem
Trennschalterkopplungsmodul (BIM) sind für bis zu 100
A ausgelegt. Bevor ein BIM ausgebaut wird, muß
unbedingt die gesamte Stromversorgung für das BIM
abgeschaltet werden und sämtliche Trennschalter auf dem
BIM müssen ausgelöst werden (O ist gedrückt).
• You must be familiar with "Safety considerations and best practices"
(page 53).
• Removing a BIP BIM causes hardware parts in the Passport 15000 or
20000 switch to lose their backup power when its mate BIM remains
powered. While one BIM of a pair is disengaged, the software reports
major alarms for the shelf and cooling unit powered by that BIM. The
label on the back of the cover of the captive screws indicates which parts
of the shelf assembly are powered by each breaker of each BIM.
1 At the front of the BIP, unfasten the slotted captive screws of the BIP screw
cover (do not use power tools), as indicated in the figure "Locations of
modules in a BIP" (page 654).
2 Swing the cover downwards.
