6.2 Charging Batteries
The batteries are valve-regulated, non-spillable, lead acid batteries and should be kept charged to attain their design life. The
UPS charges the batteries continuously when it is connected to the utility input power.
If the UPS will be stored for a long time, we recommend connecting the UPS to input power for at least 24 hours every 4 to 6
months to ensure full recharge of the batteries.
6.3 Checking UPS Operation
NOTE: Operation check procedures may interrupt output power supplied to the connected load.
We recommend checking the UPS operation once every 6 months. Ensure that output power loss to the connected load will
not cause data loss or other errors before conducting the check.
1. Press the Enter button to check the indicators and display function, see Operation and Display Panel on page55.
2. Check for any alarm or fault indicators on the operation/display panel.
3. Make sure that there are no audible or silenced alarms. Select the Log, and look at the Current tab for alarm and
fault history, see Log Screen on page69.
4. Check the flow screen to ensure the UPS is operating in Normal mode. If the UPS is operating in Bypass mode,
contact Vertiv Technical Support.
5. Check the flow screen to see if batteries are discharging (operating in Battery mode) while utility power is
normal. If so, contact Vertiv Technical Support.
6.4 Cleaning the UPS
WARNING! Risk of electric shock. Can cause injury or death. Disconnect all local and remote electric power
supplies before working with the UPS. Ensure that the unit is shut down and power has been disconnected
before beginning any maintenance.
The UPS requires no internal cleaning. If the outside of the UPS becomes dusty, wipe with a dry cloth. Do not use liquid or
aerosol cleaners. Do not insert any objects into the ventilation holes or other openings in the UPS.
