User Manual
RMS-RELAY02B Configurations
RMS-RELAY02B configurations are used to associate the DI/DO status of the external dry
contact card and UPS status. You can disable the functions of the external dry contact card by
disabling RMS-RELAY02B input. The SNMP card changes the DO output status by setting
the DO type and associated event. The SNMP card controls UPS startup/shutdown based on
the configured DI type and DI input status.

 The alarm content includes the alarm device, alarm severity, alarm ID, alarm cause ID, alarm name,
generation time, and clearance time.
 Alarm sending example: If the SNMP card is powered on between 8:00 and 8:59, the SNMP card
will check whether the alarm notification has been sent at 8:00. If it has been sent, the SNMP card
will not send again. If it has not been sent, the SNMP card will send it. If the SNMP card is powered
on between 9:00 and 11:59, the alarm notification will not be sent. It will be sent at 12:00.
For DO1 to DO4:
The NO and COM pins of DO are closed, and the NC and COM pins of DO are open,
when the associated event is consistent with the UPS status; otherwise, the NC and COM
pins of DO are closed, and the NO and COM pins of DO are open.
For DI1 and DI2:
If Type is set to NO, the UPS executes the configured associated event when DI has a
12–24 V DC input; otherwise, the UPS does not execute the associated event. If Type is
set to NC, the UPS does not execute the configured associated event when DI has a
12–24 V DC input; otherwise, the UPS executes the associated event.
The UPS performs the shutdown command if Type is set to NO, DI1 is set to Startup, DI2 is set to
Shutdown, and there is a 12–24 V DC input. If the UPS is faulty, it does not perform the startup
command when DI is set to Startup. Rectify the UPS fault first.
