ATTENTION !!!
There are no parts inside the UPS or battery group that needs service or maintenance work that
should be done by user. Therefore DO NOT OPEN THE COVER OF UPS. Never touch on any terminal of battery
group. There is risk of electric shock inside the UPS even when it is completely turned off (because of energy
storage components). Therefore unauthorized openning of the UPS cabinet for repairment, maintenance etc. is not

5.1 Scheduled Maintenance
Some parts and components used inside UPS requires periodic maintenance by service personnel. Besides,
some power equipment inside the UPS need good air circulation for cooling functions. In this case, the UPS
should be cleaned against dust periodically. Cooling fans are mechanical and moving parts and they should be
checked periodically for this reason. Also the batteries should be checked periodically that if they are in good
condition or not.
LION Series UPS informs the user about these procedures when the maintenance time is up with its 3
independent hour counter as warnings:
FAN MAINTENANCE counter
BATTERY MAINTENANCE counter
GENERAL MAINTENANCE counter
This type of protective maintenance prevents small problems turning up to big failures.
LION Series UPS has been designed to require very low user maintenance work. User should only make
below maintenance procedure for long years of trouble-free operation.
