Magnum 6K32T & 6K32TRC Managed Switch Installation and User Guide 05/07)

The actual connection procedure is very straightforward. Simply connect the leads to the Magnum unit, beginning with ground. Ensure that each lead is securely tightened.

Note: The GND should be hooked up first. The 6K32T & 6K32TRC 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 “+”.

An ON-OFF manual switch is optional for DC power. This can be used to cut off power connections and as a RESET for the Magnum 6K32T & 6K32TRC Switch.

B4.1 UL Requirements for DC-powered units

1.Minimum 18AWG cable for connection to a Centralized DC power source.
