Magnum Quad-Series Fiber Switches

Installation and User Guide (06/03)

The 24, 100 and 125VDC options are particularly useful in the Industrial environment, where it is common for facilities to operate on 24VDC or 125VDC power. The 100 and 125VDC options are 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 -48VDC, 24, 100 and 125VDC power source leads to the DC power terminal block on the Magnum Quad-Series Switches. (see figure at the right with –48VDC power as example).

Figure B4.1: -48VDC Terminal Block on Magnum Quad-Series Switches -48VDC

In this picture, the -48VDC terminal block on the Magnum Quad-Series Switch is located on the rear of the unit and is equipped with three (3) screw-down lead posts. It is similar for 24, 100 and 125VDC options on the Quad-Series Switch. The leads are identified as negative (-), positive (+), 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 Quad-Series Switch 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, 24, 100 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 the DC 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 switch.

B4.1 UL Requirements

1.Minimum 14 AWG cable for connection to a Centralized DC power source.

2.Fastening torque of the lugs on the terminal block: 9 inch pound max.

3.Centralized DC Power Source cable securement, use at least four cable ties to secure the cable to the rack at least 4 inches apart with the first one located within 6 inches of the terminal block.

B5.0 OPERATION

Operation of the Magnum Quad-Series Switch with the optional -48VDC, 24V, 100 and 125VDC power supply is identical to that of the AC-powered models.
