NOTE: The GND should be hooked up first. The 6KM 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 input connector of –48VDC,
12VDC, 24VDC, 110VDC, 125VDC or 250VDC products, 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 “+”.
After confirmation of the output voltage:
1. Turn off power to the supply line.
2. Connect supply line to the unit.
3. Apply power to the supply line.
4. Confirm that the PWR led is illuminated.
