AEG Protect C.R Operating Instructions Manual page 12

When replacing the batteries, the following must be observed:
Only ever use identical maintenance-free sealed lead
batteries with the same data as the original batteries.
Danger! Explosive!
Never throw batteries into open fire.
Never open or damage batteries. (Electrolyte
may leak out and damage skin and eyes. It may
be toxic!)
Batteries can cause electric shocks and high
short-circuit currents.
Take the following safety precautions when working with the
batteries:
 Take off watches, rings and other metallic objects!
 Always use tools with insulated handles!
Do not switch loads on and off using the UPS
i
main switch. Do not use multiple outlet adapters
with a central on/off switch, in order to avoid
peak inrush currents.
Switch OFF the UPS using its main switch "OFF" if you do not
intend to use it for some time. PROTECT C.R must be
switched off every evening if the electricity supply in your
company is switched off every night. Otherwise, the battery
will be discharged (assumed power failure). Frequent and
complete discharging of the battery leads to a shorter service
life of the battery and should therefore be avoided!
For personal safety reasons, never switch on the
main switch when the mains connector of
PROTECT C.R is disconnected!
