Low Voltage system upgrade:

LB System Cables

• LB system for RE4 needs new cabling (from LBB to USC) and room for crates

• RE1/1 requires no new cabling, LBBoxes installed

• RE1/1 requires room for Power Supplies

Krzysztof Doroba, RPC TRigger Review, 22.01.2009

Questions:• room for RE1/1 LV PS at YE+1,YE-1?
