Remove the Current Sense Circuit Board
Follow these steps to remove and replace the current sense circuit board.
1. Review the Product Advisories on page 14
.
2. Remove power from the system. See Remove Power from the System on
page 15
.
3. Open the corresponding power bay enclosure door.
4. Remove the LCL filter module from the enclosure. See LCL Filter Module
Replacement on page 257
.
5. If installed, remove the EMC filter circuit board from the LCL filter
module. See AC Common Mode Filter Circuit Board Replacement on
page 268
.
6. Without bending the cable to a radius less than 50 mm (2 in.), disconnect
the fiber-optic cable from the transceiver in the LCL port on the current
sense circuit board.
7. Remove the transceiver from the LCL port on the current sense circuit
board. Retain the transceiver for reuse.
IMPORTANT
Minimum inside bend radius for fiber-optic cable is 50 mm
(2 in.). Any bends with a shorter inside radius can
permanently damage the fiber-optic cable. Signal
attenuation increases as inside bend radius is decreased.
