1. 

One power supply unit including 6 ft. (1.8 m) AC power cord with AC unit 

2. 

Air temperature measured at the air inlet of the chassis 

3. 

Recommended for use only in non-condensing environments 

 

Only one (1) power supply unit is needed to power up to two HDRx rack units.  To provide redundant operation 
two (2) power supply units are needed.  The power cables are connected on the rear of the chassis.  One cable is 
included with the chassis.  An extra cable must be ordered separately.  See ordering information. 
 
Same or different power sources may be applied.  One of the power supplies may be an AC powered unit and the 
other power supply may be a DC powered unit.  In the event of AC power failure the DC powered unit will then act 
as backup.
