Before connecting to Terminal block of–48VDC, 24VDC or 125VDC,  always 
use a digital voltmeter to measure the output voltage of the power supply and 
determine the lead which is  more “+ve potential”. The more “+ve” voltage lead from 
48V  or –48V supply must be connected to the post labeled “+”. 
 
 
The connection procedure is straightforward. Simply connect the DC leads to 
the Switch’s power terminals, positive (+) and negative (-) screws. The use of Ground 
(GND) is optional; it connects to the chassis. Ensure that each lead is securely tightened.  
The 24VDC & 125VDC terminal block on Magnum 4K-Series Switch also has 
everything similar to –48VDC info. Described above. 
 
 
C5.1  UL Requirements 
 
The following must be adhered to in order to conform to UL requirements: 
1.   Minimum 14 AWG cable for connection to a Centralized DC power source. 
2.   Fastening torque of the lugs on the terminal block:  9 inch pound max. 
3.   Centralized DC Power Source cable securement, use at least four cable ties to 
secure the cable to the rack at least 4 inches apart with the first one located 
within 6 inches of the terminal block.
 
 
C6.0 ORDERING 
INFORMATION 
 
To order the optional Dual-Source -48VDC power supply factory installed, 
order “Dual-Src48V” as a separate line item following the product model. 
 
    Example: Magnum 4K16-48VDC  
 
 
  Dual-Src-48V for regular model with no ON-OFF switch 
 
 
  Or Dual-Src48V-SWITCH for model with ON-OFF switch 
 
 
Similarly, order “Dual-Src24V” or “Dual-Src125V” as a separate line item 
following the product model. 
  
Example: 
Magnum 4K16-24VDC or Magnum 4K16-125VDC 
 
   
  Dual-Src24V for regular model with no ON-OFF switch 
 
   
  Dual-Src24V-SWITCH for model with ON-OFF switch
