The UPS is an electrical device that can be dangerous. The device should only ever be opened by specially trained technicians. Repairs are to be made by qualified customer-service personnel only!

The output can also be electrically charged, even if the UPS is not connected to the mains power supply. The UPS has its own internal power supply (battery)!

To ensure operator protection, the device must be properly grounded!

The PROTECT D. must only be connected and operated with a VDE-approved power cord with a grounding conductor to 220 V / 230 V / 240 V AC voltage networks with a protective ground.

Caution – Risk of burns!

The battery has a high short-circuit current. Any incorrect connection or error made in disconnection can lead to the melting of plug connections, to arcing and to serious burns!

The device is equipped with a warning signal that sounds when the PROTECT D. battery power is dead or when the UPS is not working in the normal mode (also see Chapter 9.1.1 “Alarm / error messages”, pg. 59).

To ensure operating safety with the UPS and the battery modules (special accessory), please note the following safety instructions:

Do not attempt to open the UPS! (there are no parts in the UPS that require regular servicing. Please note that if the UPS has been opened, any warranty claims will no longer apply)

Do not expose the device to direct sunlight or a direct heat source!

The device is designed to be installed in heated rooms indoors. Do not install the device close to water or in very humid areas!
