Installing the AN/DC

Space Requirements

The installation site must provide a certain amount of free space around the AN/DC to dissipate heat. Install the AN/DC in a space that meets the following specifications:

•Width: 19.5 in. (49.6 cm)

•Minimum depth: 15.5 in. (39.3 cm)

•Depth for servicing: 24.5 in. (62.2 cm)

Electrical Requirements

The installation site must provide an isolated power source that meets these electrical specifications:

•Input voltage of -48.0 or -60.0 volts DC, +/- 20%

•1.5 amperes (A) input current under full load at -38.0 VDC input

•Reinforced insulation from the main AC power

We recommend the use of #16 AWG cables between the AN/DC and the power source to minimize voltage drop. When measuring the cable run, be certain to include both the input and return cables.

Environmental Requirements

The AN/DC installation site must meet the following specifications:

•Altitude: 0 to 8,000 ft (0 to 2,438.4 m)

•Humidity: 10% to 90%, noncondensing

•Temperature: 32 °F to 104°F (0°C to 40°C) stable
