Installing an Alpine 3808 or Alpine 3804
DC Power Supply
To install an Alpine 3808 or Alpine 3804 DC power supply, complete the following tasks:
•
Select the cabling.
•
Install the DC power supply.
•
Attach the cables and supply power.
•
Verify a successful installation.
For centralized DC power connections, install only in a restricted access area.
Selecting and Preparing DC Cabling
Use the following guidelines when selecting cabling for the DC power supplies:
•
Each DC power supply requires:
—
30 A (Alpine 3808) at -48 VDC nominal
—
16.5 A (Alpine 3804) at -48 VDC nominal
Or equivalent power between -40 and -70 VDC.
•
For DC power and ground cables, use:
—
8 AWG, high-strand count copper wire cable (Alpine 3808)
—
10 AWG, high-strand-count copper wire cable (Alpine 3804)
Use power cables with the specifications outlined in Table 31.
For convenience, the necessary connection lugs used to connect the source DC cables to the power
terminals are loosely mounted on the studs of the DC power supply. using lock washers and nuts.
To attach the cable to the lugs:
1
Strip 0.5 inch (1.27 cm) of insulation from the appropriate AWG, high-strand-count copper cable.
2
Insert the cable into the cable lug.
3
Using a 1/4-inch or 5/16-inch screwdriver, tighten the cable retention screw to 20 inch-pounds of
torque.
