.0 10ETS/XTS, 24/48VDC, 90-250VDC INSTALLATION
This section describes the proper connection of the 24/48VDC, leads to the DC
power terminal block on the Magnum 10ETS/XTS Terminal Server.
The DC terminal
block on the Magnum 10ETS/XTS is located on the right rear or left front (Reverse unit)
of the unit and is equipped with four (6) screw-down lead posts. The power terminals are
identified as positive (+/L) and negative (-/N), and they are electrically floating inside
the unit so that either may be grounded by the user if desired. The chassis is “earth” or
ground (GND).
The connection procedure is straightforward. Simply insert the DC leads to the
Switch’s power terminals, positive (+/L) and negative (-/N) screws. The use of Ground
(GND) connects to the Switch chassis screw provided under the DC terminal. Ensure that
each lead is securely tightened.
Note: The GND should be hooked up first. The 10ETS/XTS unit has a floating ground,
so the user may elect to Ground 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 “+”.
When power is applied, the green PWR LED will illuminate.
Note: The 10ETS/XTS unit has a floating ground, so the user may elect to Ground
either + or - terminal to suit the customer’s use.
