user may elect to Ground either + or = terminal to suit the customer’s use. 
 
Before connecting hot lines to the 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 Switch chassis. Ensure that each lead is securely 
tightened.  
 
The 24VDC & 125VDC terminal block on Magnum 6K25’s is similar to that 
described in the –48VDC information above.
 
 
C5.1  UL Requirements 
 
The following must be adhered to in order to conform to UL requirements: 
1.   Minimum 18 AWG cable for connection to a Centralized DC power source. 
2.   Minimum 14 AWG cable for connection to earthing wiring. 
3.   Use only with Listed 10 A circuit breaker provided in building installation. 
4.   
“Complies with FDA radiation performance standards, 21 CFR subchapter J.” 
or equivalent. 
5.   Fastening torque of the lugs on the terminal block:  9 inch pound max. 
6.   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 6K25R-48VDC  
 
 
  Dual-Src-48V   for the regular DS model with no ON-OFF switch 
 
             or    Dual-Src48V-SWITCH   with the ON-OFF manual switch. 
 
 
Similarly, order the “Dual –source 24VDC” or “Dual-source 125VDC” as a 
separate line item following the product model.  
  
Example: 
Magnum 6K25R-24VDC or Magnum 6K25R-125VDC 
  
 Dual-Src24V 
for regular models with no ON-OFF switch 
   
Or Dual-Src125V-Switch for models with the ON-OFF switch

OPERATION   
 
 Operation of the Dual-Source Magnum 6Ks-48VDC, 24VDC and 125VDC 
Switch models are identical to that of the standard models.
