The -48VDC terminal block on the Magnum 6K16-Series Switch, as shown in Fig C5.0
is located on the left front of the unit and is equipped with
five (5) screw-down lead
posts. The primary terminals are identified as positive (A+), negative
(A-), and the secondary power terminals as negative (B-), positive(B+). The chassis
“earth” or ground (GND) is a threaded post with a #6 nut. The Dual Source terminal
block for the 24VDC and 125VDC are similar.

Terminal Block on a Magnum -48VDC with Dual-Source option
Note: The GND should be hooked up first. The 6K16-Series unit has a floating ground,
so the 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 6K16-Series’s is similar to
that described in the –48VDC information above.
