Installing the AN/DC
312410-A Rev 00
1-5
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
