Safety measures
When operating electric devices, it is unavoidable
for certain parts of these devices to conduct haz-
ardous voltage. Consequently, severe bodily injury
or material damage can occur if they are not handled
properly:
• Before making connections to the device, ground
the device by means of the ground wire connec-
tion, if present.
• Hazardous voltages can be present in all circuitry
parts that are connected to the power supply.
• There can still be hazardous voltages present in the
device even after it has been disconnected from
the supply voltage (capacitor storage).
• Do not operate equipment with current transformer
circuits when open.

Safety measures
When operating electric devices, it is unavoidable
for certain parts of these devices to conduct haz-
ardous voltage. Consequently, severe bodily injury
or material damage can occur if they are not handled
properly:
• Before making connections to the device, ground
the device by means of the ground wire connec-
tion, if present.
• Hazardous voltages can be present in all circuitry
parts that are connected to the power supply.
• There can still be hazardous voltages present in the
device even after it has been disconnected from
the supply voltage (capacitor storage).
• Do not operate equipment with current transformer
circuits when open.
• Do not exceed the limit values specified in the user
manual and on the rating plate! This must also be
observed during testing and commissioning!

Safety measures
When operating electric devices, it is unavoidable
for certain parts of these devices to conduct haz-
ardous voltage. Consequently, severe bodily injury
or material damage can occur if they are not handled
properly:
• Before making connections to the device, ground
the device by means of the ground wire connec-
tion, if present.
• Hazardous voltages can be present in all circuitry
parts that are connected to the power supply.
• There can still be hazardous voltages present in the
device even after it has been disconnected from
the supply voltage (capacitor storage).
• Do not operate equipment with current transformer
circuits when open.
• Do not exceed the limit values specified in the user

Safety measures
When operating electric devices, it is unavoidable
for certain parts of these devices to conduct haz-
ardous voltage. Consequently, severe bodily injury
or material damage can occur if they are not handled
properly:
• Before making connections to the device, ground
the device by means of the ground wire connec-
tion, if present.
• Hazardous voltages can be present in all circuitry
parts that are connected to the power supply.
• There can still be hazardous voltages present in the
device even after it has been disconnected from
the supply voltage (capacitor storage).
• Do not operate equipment with current transformer
circuits when open.
• Do not exceed the limit values specified in the user
manual and on the rating plate! This must also be
observed during testing and commissioning!
