– Only use suitable power cables when connecting the UPS to the
mains power supply and pay attention to the required current carry-
ing capacity;
– Only use suitable power cables when connecting loads to the UPS
and pay attention to the required current carrying capacity;
– The safeguarding of loads should, whenever possible, be performed
directly in front of a load, less centrally in front of the UPS;
– Never operate any household devices or tools such as, e.g. heaters,
vacuum cleaners, electric drills, hairdryers, toasters, or sensitive de-
vices such as, e.g., scanners or medical devices by means of the
UPS;
– Do not connect any loads or appliances to the UPS that could over-
load the device, such as, e.g., printers, copiers, etc.;
– In general, use appropriate tools for the installation.
2.8 Operation
Only qualified personnel are permitted to access and operate the device, espe-
cially if the UPS is supporting sensitive loads.
In all situations, it must be kept in mind that the UPS contains an energy storage
unit. This means that the UPS can also be carrying a current at the output even
when the UPS has already been disconnected from the mains power supply.
The UPS output is first de-energized when the device has completely shut down
and has been disconnected from the mains power supply.
2.9 Working with accumulators
When handling accumulators, there is always a risk of electric shock, burns
and/or chemical burns.
For this reason, unauthorized personnel should not have access to accumula-
tors.
Accumulators or their connection lines can cause electric shock.
In the event of a short-circuit of the accumulators, touching the current-carrying
parts can result in severe burns.
Do not place accumulators in the vicinity of heat sources and do not bring them
into contact with open fire. Risk of explosion!
