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 6KQE 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.
