Connecting -48V DC Power Supplies

The GigaVUE-HC2 is available with DC power supplies. This section provides instructions for connecting a -48V DC power source to the DC power supplies.

To connect a -48V DC input to the screw terminal DC power supply:
1.   Remove the safety cover from the power terminals.
2. Connect the power supply ground terminal () to earth ground.

 

Figure 83: DC Power Module

3. Connect the positive and negative power cables to the screw terminals using a Phillips screwdriver.
The top connector on the DC power supply is the 0V connector.
The bottom connector on the DC power supply is the -48V connector.
4. Replace the safety cover over the power terminals.

1Connect the neutral and negative power cables to the DC power source as follows:

Connect the neutral wire to the 0V (RTN) connector on the DC power source.
Connect the negative wire to the -48V connector on the DC power source.

Important: As shown in Figure 83: DC Power Module , the leads to the DC power supplies on the GigaVUE-HC2 node should attach from the side of the chassis away from the terminal block. Run the wires to avoid obstructing airflow for the adjacent fans.

5. Repeat Step 2 through Step 5 for the other power supply in the GigaVUE-HC2 chassis:
