DC Output Connectors
The power supply has four DC output connectors on the front panel, two
positive (+) and two negative (-). Here are the connector guidelines:

You can use either of the positive connectors with either of the
negative connectors. (The positive connectors are connected
internally in the power supply as are the two negative connectors.)

You can adjust the DC output of the connectors with the TRM
screw on the front panel. The range is 45.0V to 55.2V. The default
is 48.0V. Refer to “TRM Screw for Adjusting the Output DC
Voltage” on page 24.

Allied Telesis recommends testing the output voltages on the
output connectors with a voltmeter and adjusting the output voltage
with the TRM screw, if necessary, before connecting powered
devices to the power supply. This is to ensure that the power
supply provides the correct DC voltage to the devices.

You can remotely turn on or off the DC output connectors using the
Remote Control circuit. Refer to “Remote Control Connector for
Turning On or Off the DC Output Connectors” on page 25.
The wire specifications for the DC output connectors are listed in Table 2.
