Installing the D9854/D9854-I Receiver
Rack Mounted
The D9854/D9854-I receiver is a 1U unit with connector access at the rear panel. The
receiver is intended for mounting in a standard 19" rack with minimum 1U spacing
between units to allow adequate ventilation/air flow.
The D9854/D9854-I receiver is vented from front to back. Multiple units can be
stacked in a rack, provided that adequate cooling is available.
Cooling
The unit is cooled by the use of internal fans. The air intake is from the front and the
air outlet is on the rear.
Note: Adequate cooling must be provided equaling 107 W (maximum) at 25°C per
unit to avoid overheating.
CAUTION:
The inlet air temperature must not exceed 50°C/122°F at any time.
Grounding
You must ensure that the unit is properly connected to ground to meet safety and
EMC requirements. Before any other connection is made, the unit must be connected
to a protected ground terminal as described below:
Via the three wire power cord of the AC power supply. This connection is
mandatory.
In addition, via the protective ground terminal on the rear panel of the unit. This
connection provides additional protection of the equipment.
Mounting the D9854/D9854-I Receiver to a Rack
1 Mount L-brackets in the rack to support each unit to be installed.
2 Place the receiver in its position in the rack.
3 Mount the receiver securely to the rack by securing the mounting flanges to the
rack using the four screws provided.
4 Make sure the air outlet holes on the back of the receiver are not obstructed to
allow air flow from the front to the back of the chassis.
