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.
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. |
