Danger of explosion!
Do not throw batteries into an open fire.
Do not attempt to open or damage the batteries (the
electrolytes released will harm skin and eyes and
can be toxic!)
Batteries can cause electrical shock and high short
circuit current.
Whenever you work with batteries, take the following
precautions:
• Remove all watches, rings and any other jewelry made of
metal!
• Use only tools with insulated handles!
i
Do not use connecting blocks with central on/off
switches to prevent switch-on current peaks.
Switch the UPS to “OFF” if you don’t want to use it for a longer
period of time. If your company switches off the power every
evening, then the PROTECT D. has to be switched off as well.
Otherwise, the battery will run down. To prolong battery life,
avoid running the battery down frequently!
For your own protection, never switch on the UPS
when the plug has been pulled from the PROTECT D.!
