♦Do not connect household appliances such as hairdryers to the UPS! Also take care when working with motor loads. It is essential to avoid back-feeding the inverter, e.g. if the load is intermittently operated in regenerative mode.

Danger! Electric shocks!

Even after the mains voltage has been disconnected, the components within the UPS remain connected to the battery and can thus cause electric shocks. It is therefore imperative to disconnect the battery circuit before carrying out any maintenance or repair work!

If it is necessary to replace the battery or carry out maintenance work, this must be done by or under the supervision of a specialist familiar with batteries and the necessary safety precautions!

Only authorized persons are allowed in the vicinity of the batteries!

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.

Therefore, take the following safety precautions when working with batteries:

♦Take off watches, rings and other metallic objects!

♦Only use tools with insulated handles!
