Safety measures
When operating electrical devices, certain parts
of these devices are invariably subjected to
hazardous voltage. Therefore, severe bodily
injuries or damage to property can occur if they
are not handled properly:

• Before connecting connections, earth the

device at the ground wire connection if
present.

• Hazardous voltages may be present in all

switching parts that are connected to the
power supply.

• Hazardous voltages may also be present

in the device even after disconnecting the
supply voltage (capacitor storage).

• Do not operate equipment with current

transformer circuits while open.

• Do not exceed the threshold values specified

in the user manual and on the rating plate.
Also adhere to this when inspecting and
commissioning.

• Observe the safety and warning instructions in

the documents that belong to the device!
