Operating Shock and Vibration: meets Bellcore GR-63-CORE Sections 4.4.1 and 4.4.3 

NOTE :  For best results at high-temperature, fasten the metal case of the PSX-A unit to be in 
contact with a vertical surface (such as pedestal) that has good heat conducting properties. 
Remove rubber “feet”, if present, to enhance metal-to-metal contact and provide the best heat 
transfer away from the PSX-A unit.

The rugged Magnum P62-5V Hardened Switch also supports 125V/250 VDC power 

through a separate Power Source unit, the PSX-T. The wide range of AC power input qualifies 
this product for use worldwide, in almost any temperature environment. The 125/250 VDC power 
source (PSX-T) provides a rugged power supply enclosed in a metal case that also acts as a heat 
sink, enabling extended temperatures to be accommodated. The PSX-T also includes reverse-
polarity protection to prevent damage in case the unit is accidentally hooked up backwards. The 
DC power output cord comes with a military-style screw-lock female plug for secure attachment 
to the P62-5V Hardened Switch.

This section describes the proper connection of the -125V/250 VDC leads to the –

125/250 VDC power terminal block on the PSX-T Power Source (as shown in Figure above) 
The –125/250 VDC terminal block on the External PSX-T is located on the left side of the unit 
and is equipped with three (3) screw-down lead posts, covered by a removable safety shield or 
cover.  The power terminals are identified as positive (+) and negative (-), and they are floating 
inside the unit so that either may be grounded by the user.  The chassis is “earth” or ground 
(GND).   
 

The connection procedure is straightforward. Simply insert the DC leads to the PSX-T’s 

power terminals, positive (+) and negative (-) screws. The use of Ground (GND) is optional; it 
connects to the PSX-T chassis. Ensure that each lead is securely tightened, then replace safety 
shield. When power is applied, the green PWR LED will illuminate 

and figure out the +ve potential lead or -ve potential lead. The more +ve potential lead will 
connect to the post labeled “+ve” and the rest to the “-ve”. 
The GND can be hooked up at the last.
