7. Operation
7.1 Operation of the UPS
The operator of the UPS-system must always adhere to the instructions
in this operating manual. The operator may only carry out the following
measures and must always exercise particular care:
 Use of the operating controls: switching-on, starting and switching-
off the UPS.
 Reading of the display messages and interpretation of the acoustic
warning signals.
 Triggering the test mode.
 Using the communication interface, whereby the connection to the
PC or other systems must already be established for UPS-devices
with permanent wiring.
Due to the extensive protective functions the UPS-system performs in re-
lation to the appliance/s, the UPS operates fully automatically. The opera-
tor only carries out the switching-on and starting or switching-off of the
device. In addition, a data exchange can take place via the communica-
tion interface or the SNMP-adapter, however, this is not absolutely nec-
essary for the general operation of the system.
