Magnum 6K25 Managed Fiber Switch

Installation and User Guide (04/06)

The 24VDC and 125VDC solution are particularly useful in the Industrial environment, where it is common facilities to operate on 24VDC or 125VDC power. The 125VDC solution is mainly used in power utilities, such as electrical substations, electrical generating plants, etc. The 24VDC applications are mainly in the Industrial environment, such as factory floor, HVAC equipment, military equipment, etc.

B4.0 INSTALLATION

This section describes the installation of the -48 VDC, 24VDC and 125VDC power source leads to the -48 VDC, 24VDC and 125VDC power terminal block on the

Magnum 6K25s. (see figure at right).	_ GND	+

In this picture, the -48VDC terminal block on the Magnum 6K25 is located on the rear of the unit and is equipped with three (3) screw-down lead posts. It is similar for 24VDC and 125VDC options on Magnum 6K25. The leads are identified as negative (-),

ON

OFF

36-70VDC

positive (+), Figure B4.0: -48VDC Terminal Block on Magnum 6K25-48VDC

and chassis ground (GND).

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 6K25 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 6K25 Switch.

B4.1 UL Requirements for DC-powered units

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

2.Minimum 14AWG cable for connection to a earthing wiring.

3.Use only with Listed 10 A circuit breaker provided in building installation.

4.“Complies with FDA radiation performance standards, 21 CFR subchapter J.” www . GarrettCom . com
