5. Unscrew the terminals for the DC +/- supply from X1 of the Gate
Driver board.
Observe polarity when removing for later re-attachment.
6. Carefully unplug the fiber optic cables from sockets along the bottom of
the Gate Driver board, and carefully set them aside.
Important: When mishandled, the ability of fiber optic cables to
transmit data is greatly diminished.
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: 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.
7. Disconnect the X13, X14, and X15 cables from sockets of the Gate
Driver board, and set them aside.
8. Remove the five screws that secure the Gate Driver board and support
bracket to the power structure.
