Check the investigation item No. 3.
3
Check for disconnection between R1/R2 terminals
of the resistor unit or check for an error in the
resistance value.
Resistor unit has disconnection, or the resistance
value is abnormal.
Replace the resistor unit.
No error.
Check the investigation item No. 4.
4
Check the reproducibility.
The error is always repeated.
Replace the power backup unit.
The state returns to normal once, but the error
occurs sometimes thereafter.
Check the investigation item No. 5.
5
Check if there is any abnormality in the unit's
ambient environment. (Ex. Ambient temperature,
noise, grounding)
Take remedies according to the causes of the abnormality in the ambient environment.
Alarm No.
1B
Capacitor connection error :
Non-connection of capacitor was detected although the capacitor unit connection is set as enabled.

of the capacitor unit.
There is disconnection between the capacitor
unit’s terminals
Replace the capacitor unit.
No error.
Check the investigation item No. 3.
3
Check the reproducibility.
The error is always repeated.
Replace the power backup unit.
The state returns to normal once, but the error
occurs sometimes thereafter.
Check the investigation item No. 4.
4
Check if there is any abnormality in the unit's
ambient environment. (Ex. Ambient temperature,
noise, grounding)
