Remove the power cord (CSA)
The power cord has a black wire and a white wire that connect to the power switch and a green ground wire that
connects to the heatsink.
1. Remove the black and white wires from the top of the power switch. You can use needle nose pliers or a straight
screwdriver to ease them off, if necessary.
Figure 7
2. Remove the screw that holds the ground wire to the heatsink. A notch in the power board provides access to the
screw. (See Figure 8.)
