Installing the Power Supply Unit (Optional)
The installation of the power supply unit (PSU) and the PSU bracket are optional. You only need to install
the PSU and PSU bracket, if you do NOT have a direct -48 Vdc power supply. The PSU allows you to
convert from another power source (i.e., North America: 120 Volts, European: 220 Volts) to -48 Vdc.
If desired, you can install the PSU onto the PSU bracket before installing the complete PSU assembly
onto the module. If you choose this method: always ensure that the AC cable is accessible from the top
of the PSU and the DC output cable is at the bottom.

Installing the PSU Bracket
To install the PSU, the PSU bracket needs to be installed onto the module.
Note:
The PSU bracket is symmetrical, and there is no specific mounting orientation.
