1. Remove power from the AFE.
See Remove Power from the AFE
on page 37.
2. If present, remove the protective barriers.
See Remove AFE Protective Barriers
on page 44.
3. Remove the airflow plate.
See Remove the AFE Airflow Plate
on page 45.
4. Remove the protective front cover and terminal cover from the power
structure.
See Remove Protective Covers from the Power Structure
on page 46.
5. Unscrew the terminals for the DC +/- supply from X1 of the gate driver
board.
Observe polarity when removing for later reattachment.
6. Carefully unplug the fiber-optic cables from sockets along the bottom of
the gate driver board, and carefully set them aside.
7. Disconnect the X13, X14, and X15 cables from sockets of the gate
driver board, and set them aside.
ATTENTION: Hazard of permanent eye damage exists when using
optical transmission equipment. This product emits intense light and
invisible radiation. Do not look into fiber-optic ports or fiber-optic
cable connectors.
IMPORTANT When mishandled, the ability of fiber-optic cables to transmit data
is greatly diminished.
IMPORTANT The minimum inside bend radius for fiber-optic cable is 25.4 mm
(1 in.). Any bends with a shorter inside radius can permanently
damage the fiber-optic cable. Signal attenuation increases with
decreased inside bend radii.
