Connecting -48V DC Power Supply Modules

The GigaVUE‑HC1 is available with DC power supply modules. This section provides instructions for connecting a -48V DC power source to the DC power supply modules.

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

1.   Plug the DC power cable adapter into the DC power supply.

Note:  Terminal block supports 10AWG.

2. If PSM grounding is required, connect earth ground to the SAFETY GROUND (green/yellow) terminal using a straight blade screwdriver.

3. Connect the positive and negative power wires to the appropriate terminals using a straight-blade screwdriver.
o   Connect positive source wire to the + RETURN (black) terminal using a straight blade screwdriver.
o   Connect -48V source wire to the -48V (blue) terminal using a straight blade screwdriver.

Important: The leads to the DC power supply modules on the GigaVUE‑HC1 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.

4. Repeat Step 2 and Step 3 for the other power supply module in the GigaVUE‑HC1 chassis.

Regional Compliance (Australia and New Zealand Standards)

This section provides guidance to ensure that the DC power cable complies with AS/NZS 5000 and AS/NZS 3015.

Note:  For compliance with ANZ standards, the DC cable can be ordered using part number PCD-00051. PCD-00051 is supported on GigaVUE‑TA25, GigaVUE‑TA200, GigaVUE‑HC1, and GigaVUE‑HC1-Plus (with D-SUB DC connector). This requirement is optional and applicable only within the Australia/New Zealand region.

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

Establishing a reliable -48V DC input connection to the power supply involves connector assembly details, cable specifications, and insulation features for optimal performance.

  1. D-sub power cable connector assembly featuring a 3v3 type socket, contacts and backshell.

  2. The table below outlines the colors and specifications of the negative cable, positive cable, and ground cables.
