5. Plug the connector into the terminal block.
The wire must be secured to the connector and tightened before plugging into the terminal block connection.
To connect the power supply's output
:
1. Use the "+" and "-" screw connections to establish the 54Vdc to the switch.
Redundancy operation
In order to ensure proper redundancy operation for the power supply unit (PSU), ensure that the output
voltage difference between the two units is kept at 0.90~1.00V for 54V supplies.
Measure output voltage of PSU 1 and PSU 2. If PSU 1 is the primary unit, then V OUT of PSU 1 must be
higher than PSU 2. In order to set the output voltage, connect the power supply to 50% load and set the
PSU 1 and PSU 2 output voltage. Alternatively, adjust an extra 0.2V of output voltage difference between
the two units at no load condition. Voltage difference during actual setup can be verified through Software
command.
Connect and configure the DC power supply
