Installing the Alpine 3800 Series DC Power Supply
Caution: When you insert a power supply, use one hand to support the power
supply from the bottom and the other hand to hold the central handle on the
front of the power supply. Do not use just the ejector/injector lever to insert a
power supply.
4 Use the central handle to guide the power supply into the bay while supporting the
supply from the bottom with your other hand.
5 Place both hands on each side of the power supply to slowly and evenly slide the
power supply into the bay. During the last inch of insertion into the chassis, place
one hand on the central handle to steady the power supply and use your other hand
to gently push the ejector/injector lever towards the power supply to engage the
power supply backplane connectors.
Caution: Do not slam the power supply into the backplane. This or other
excessive force will cause damage and possibly require the return of the
chassis.
6 Secure the power supply by tightening the screw on the ejector/injector lever using
a #2 Phillips screwdriver.
7 Slide the locking latch away from the remove position.
8 Remove the plexiglas cover that shields the power connection on the power supply.
9 Attach the DC power and ground cables to the power supply, as shown in Figure 8-5
and Figure 8-6.
