Space Requirements
The installation site must provide a certain amount of free space around the
ANH-8/DC to dissipate heat. Install the ANH-8/DC in a space that meets these
specifications:
Width: 19.25 in. (48.9 cm)
Minimum depth: 17.25 in. (43.8 cm)
Depth for servicing: 26.25 in. (66.7 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
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.
Note:
The AN/DC should be installed only in dedicated equipment rooms
where access is limited to qualified service personnel.
