4.- MAINTENANCE
PROCEDURE
1º
If the UPS does not provide the expected back up time, recharge the battery for at
least 8 hours. If the autonomy is still low replace the battery. (Take care not to
damage the LEDs’ cover during the replacement).
Replace the battery with the same type as originally installed ( Sealed lead acid, maintenance free 12V
- 7Ah), supplied by the UPS manufacturer (Chloride Part. No.580085.000) with a polarised connector.
The battery contains toxic materials. Dispose of battery properly (must be recycled).
2º
Look inside the unit and look for any damage. (Take care not to damage the LEDs’
cover when you are opening the unit).
3º
Check battery fuses. If the fuses are broken we can change them but not without
knowing the cause of this failure.
The battery fuses are on the PCB. They are automotive fuses of 30A and 32V
4º
Connect the UPS to the mains for 1 or 2 seconds, this is only to wake-up its circuits .
5º
Check the historic to find the possible fault. If the unit doesn’t communicate perhaps
there’s something wrong in the communication circuit or in the microprocessor or with
the voltage.
6º
Use the soft to verify that the system variables have the right values.
7º
Apply the mains and wait for the start up. If the unit doesn’t start, check the
“AUTOTEST BYTE” and see why it hasn’t started. If everything is right, check the
“STATUS BYTE” to verify if the unit was stopped by Software or by “TIMER”.
8º
When the UPS is operating, we must calibrate it with the automatic calibration
program.
9º
Finally, discharge the unit for a few minutes with the nominal charge and later plug the
unit to the mains for at least eight hours to totally charge the battery.
NOTE:
In the next figure you can see the correct position of the PCB wires.
Recommended for security, put the black wire (Neg. Batt.) in the last position.
And take care not to touch the heatsinks with this wire.
REVISION NOTE : If any repair or modification, affecting the revision of the equipment, is
carried out, then this situation should be reflected on the identification sticker.
