Appendix
• Before powering on the OAU 2A, ensure that the DC power cable has been installed.
• You are familiar with the safety precautions for DC power supply.
• Power on the equipment within 24 hours of unpacking.
• During maintenance, the power-off time of the equipment must not be longer than 24 hours.
• Do not connect the OAU 2A to an AC power supply device. Otherwise, the OAU 2A may be damaged.
• Do not connect the RTN 320 to a DC power supply device providing power beyond the range of –38.4 V to –
57.6 V. Otherwise, the RTN 320 may be damaged.
• If the PI is used to output DC power, the DIP switching for setting the power output mode should be set
correctly so that the DC OUT mode is selected. After setting the DIP switch, switch off the power supply. After
waiting for 6 seconds, switch on the power supply again.
