Connecting -48V DC Power Supply Modules

The GigaVUE‑HC3 is available with DC power supply modules. This section provides instructions for connecting a -48V DC power source to the DC PSMs. 1 shows a DC power supply module.

1 DC Power Supply Module

To connect a -48V DC input to the screw terminal DC power supply module:

1.   Remove the safety cover from the power terminals.
2. Connect the power supply module ground terminal () to earth ground.
3. Connect the positive and negative power cables to the screw terminals using a Phillips screwdriver.
o   The top connector on the DC power supply module is the 0V connector.
o   The bottom connector on the DC power supply module is the -48V connector.
4. Replace the safety cover over the power terminals.
5. Connect the neutral and negative power cables to the DC power source as follows:
o   Connect the neutral wire to the 0V (RTN) connector on the DC power source.
o   Connect the negative wire to the -48V connector on the DC power source.
6. Repeat Step 2 through Step 5 for the other PSMs in the GigaVUE‑HC3 chassis:
