Safety measures
When operating electrical devices,
specific parts of these devices inevi-
tably carry dangerous voltage. As a
result, serious bodily harm or property
damage can occur if they are not
handled correctly:
· Before connecting the device,
ground it at the protective conductor
terminal if available.
· Dangerous voltages may be present
in all circuit parts connected to the
voltage supply.
· There may still be dangerous
voltages present in the device even
after it is disconnected from the
supply voltage (capacitor storage).
· Do not operate operating equip-
ment with open current transformer
circuits.
· Do not exceed the limit values
specified in the user manual and on
the rating plate. This must also be
observed during inspections and
commissioning.
· Observe the safety instructions and
warning notices in the documents
that accompany the devices.
Qualified personnel
To prevent personal injuries and proper-
ty damage, only qualified personnel
with electrical engineering training may
work on the device. They must also
have knowledge
· Of the national accident prevention
regulations
· In safety technology standards
· In the installation, commissioning and
operation of the device.
