Application examples
Parallel connection of the power storage devices
To increase the buffer time, a maximum of 15 power storage
devices can be switched in parallel. It is recommended to
keep the number as low as possible and use power storage
devices with a higher capacity of necessary. For parallel op-
eration, only use power storage devices with the same batch
number .
After discharging of the power storage device, the recharging
time depends on the maximum charging current that the UPS
can make available.
Use a suitable fuse. Flat-type fuse inserts with the same nom-
inal values from the battery used are recommended.
If possible, install at a cool location e. ? g., at the bottom of the
control cabinet to ensure optimum function. For this, the fol-
lowing cabling design is advantageous.
