  2. Install the power supply unit(s) into the system housing.
  3. Attach dc power cord(s) to the product.
    • Ensure correct polarity of -48 V dc connections: RTN is + and -Vin (typical -48 V) dc is -. Earth ground should be connected very well.
  4. Connect dc power cord(s) to subject power source(s).
  5. Turn ON all the power source(s).
  1. Disconnect or turn off the subject dc power source(s) (at the breaker panel) before removing the power supply unit(s).
