The AC-powered cabinet uses the EPS30-4815AF power system to convert the AC input into the DC power for power distribution.
The EPS30-4815AF power system converts one AC input into two DC outputs to implement the DC power distribution. It can be connected to one set of batteries and use its monitoring module to manage the batteries.
The EPS30-4815AF power system can also use the external sensor transfer box to collect and report the status of sensors and standby detected parameters.
NOTE:The rectifier modules of the EPS30-4815AF power system work in the load balancing and mutual hot backup mode.
Figure 4-1 shows the appearance of the EPS30-4815AF power system.

Table 4-3 describes the indicators on the rectifier module of the EPS30-4815AF power system.
Table 4-3 Indicators on the rectifier module of the EPS30-4815AF power system|
Indicator |
Status |
Description |
|---|---|---|
|
RUN |
Steady green |
The rectifier module functions properly. |
|
Off |
This indicator is off when the red indicator is on or the yellow indicator is on (not caused by output overcurrent). |
|
|
ALM |
Steady yellow |
The ALM indicator of the rectifier module is valid when PS-off, OTP, and primary protection are valid, or when overcurrent occurs. |
|
Blinking yellow |
The communication of the rectifier module is interrupted. |
|
|
Off |
The rectifier module functions properly. |
|
|
FAULT |
Steady red |
The FAULT indicator of the rectifier module is valid when PS-enable and Vo-OV are valid, or when fan fault, no output, or output short circuit occurs. |
|
Off |
The rectifier module functions properly. |
Table 4-4 describes the indicators on the monitoring module of the EPS30-4815AF power system.
Table 4-4 Indicators on the monitoring module of the EPS30-4815AF power system|
Indicator |
Status |
Description |
|---|---|---|
|
RUN |
Green and blinking 1s on and 1s off |
The monitoring module functions properly. |
|
Blinking green quickly |
The monitoring module hardware is normal but the communication between the monitoring module and the upper device is abnormal. |
|
|
Off |
The monitoring module is faulty or there is no power input. |
|
|
ALM |
Steady red |
The system generates a critical alarm or the battery is disconnected. |
|
Off |
The system does not generate any critical alarm and the battery is already connected. |
The EPS30-4815AF power system supports one 220 V AC power input and the standard 3-pin connector is used.
Figure 4-2 shows the input terminals of the EPS30-4815AF power system.
Figure 4-2 Input terminals of the EPS30-4815AF power systemThe EPS30-4815AF power system supports three output terminals. The two pins on the left of the output terminal are the output positive pole and the two pins on the right of the output terminal are the output negative pole.
Figure 4-3 shows the output terminals of the EPS30-4815AF power system.
