Magnum 6KQ Managed Field Switch Installation and User Guide
C5.0 INSTALLATION
This section describes the proper connection of the -48VDC, 12VDC, 24VDC,
125VDC and 250VDC dual source leads to the power terminal block on the Magnum
6KQ Switch (shown in Figure to the above)
The terminal block is located on the left front of the unit next to the Alarm
terminal block and is equipped with four (4) 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 is earth/ground (GND). The Dual Source terminal block for the 12, 24, 48, 125
and 250VDC are the same.
Note: The GND should be hooked up first. The 6KQ unit has a floating
ground, so the user may elect to Ground either + or = terminal to suit the
customer's use. Before connecting live power lines to the terminal block,
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 a +ve or –ve power 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.
