DC Outputs 
 
• 
The DC outlets are floating to meet the isolation requirements for powering Power 
over Ethernet IEEE802.3af
 compatible devices.  
In non-Power over Ethernet applications the positive or negative output of the DC 
outlets can be referenced to earth, if required. 
• 
On APS3-06X (desktop versions), run the load cables through the supplied nylon 
strain relief clamps.  Failure to fit the strain relief clamps and using the incorrect 
torque setting for tightening their captive screws voids all safety approvals. 
 
 
Rectifiers 
 
• 
To reduce the risk of electric shock and maintain optimum system cooling, always 
cover empty rectifier slots with blanking panels (Part Number: IPN 621-05722-63A). 
• 
To avoid electrical shock, do not place hands inside the rectifier shelf. 
• 
Rectifier cases may exceed 100ºC (212ºF), especially after prolonged operation.  Use 
suitable gloves to remove the hot rectifier. 
• 
Do not attempt to disassemble rectifiers.  Return them, (in their original packaging) 
along with the completed Equipment Incident Report, to your local Powerware DC 
product representative for replacement or repair. 
 

Location and Environment 
 
• 
Data Power Solutions (rack-mounted and desktop versions) meet the safety and fire 
enclosure requirements (as specified in AS/NZS 60950.1, EN 60950-1, IEC 60950-1 
and UL 60950-1).  Always mount APS3-05X and APS6-05X powers systems in 19-inch 
wide host equipment racks (enclosed or open type) securely bolted to the floor and 
position the desktop versions (APS3-06X) on a surface that supports the weight (12kg 
/ 26lb) of the power system. 
• 
To maintain optimum system cooling, keep the front and rear of the power system 
clear from walls or other equipment.  The minimum recommended clearance distance 
at the front and rear of the power system is 50 mm (2”).  No top and bottom clearance 
is required. 
• 
The location must provide adequate airflow around the unit, in an atmosphere free 
from excessive dust, corrosive fumes or conductive contaminants. 
• 
Dust build-up within the DC power system may cause premature failure. In dusty 
environments filter the ventilation air entering the equipment room. Ensure regular 
cleaning of the air filters. 
• 
Do not allow water or any foreign object to enter the power system.  Do not place 
objects containing liquid on top of or near the unit. 
• 
Flooded cell and VRLA lead acid batteries can emit explosive gases and must be 
installed with adequate ventilation. Refer to the battery manufacturer or supplier for 
advice on minimum ventilation levels, or refer to Application Note AN0080 available 
from Eaton.
