Relay Contacts and LED Indicators
1) While replacing the FAIL battery with system in ON State, user MUST wait for 30 s after removing the FAIL battery and replace with new. In case the user
replaces battery within 30 s and accidently connects the battery in reverse polarity, this may cause the DC-UPS MODULE TO BE DAMAGED!
2) In this case, power supply is Turned ON with full system configuration (as shown in page 7) the module will indicate if the input connections are reverse.

Troubleshooting
LED Display Status Problem Suggestion
Normal mode (Charging)
•All LED display status are OFF.
•DC-UPS module does not operate.
1) Please check wiring and PSU output.
2) Replace DC-UPS module.
Normal mode (Charging)
•Green LED display status is flashing
quickly.
•Red LED display status is On
(not flashing).
1) The input voltage is low (18-21 Vdc).
2) Re-check input voltage and increase to > 21 Vdc.
Normal mode (Charging)
•Orange LED display status is On
(not flashing).
1) Check the Replace BAT relay contact. If it is “Close”,
this either means:
- Battery connection is open or there is no battery
- Battery reverse polarity
- Battery spoil
2) Check battery polarity connection at “BAT. IN”
terminal and make corrections.
3) Check input polarity connection at “DC IN” terminal
and make corrections.
4) Re-check battery voltage. If the battery still fails to
function and will not charge, replace with a new
battery (21-27.6 Vdc).

Troubleshooting
LED Display Status Problem Suggestion
Buffering mode (Buffering)
•Orange LED display status is flashing
slowly.
1) If there is no output voltage, this means the set
buffering time has expired.
2) Restart the DC-UPS module to reset the buffering
time.
Normal mode (Charging)
•RED LED display status is On
(not flashing).
1) Check the Replace BAT relay contact. If it is “Open”,
this either means:
-DC-UPS module is over temperature
- Battery module is over temperature (if the Rx/Tx or
battery sensor function is used)
-DC-UPS module’s output is overload
2) Check the surrounding air temperature for DC-UPS
module or battery module.
3) Check if system is loading over the DC-
UPS module’s
current limit.
