results in death or lethal injuries due to electric shock.
• Do not touch non-insulated parts or cables.
• Before performing any work or opening the product, short-circuit the secondary circuits of the current
transformers through an external short circuit device, externally disconnect the supply voltage and cables for
the current and voltage measurement.
• Observe all safety information on components associated with the product.
• Wear suitable personal protective equipment for all work on the product.
• Always perform all work in accordance with the locally applicable standards, directives and laws.
• Cover or isolate all live components.
DANGER
Danger to life due to electric arcs if measuring device is not connected correctly
If the measurement points are incorrectly contacted, this can cause an electric arc. Electric arcs can result in death
or serious injury.
• Select the appropriate measurement range on the measuring device.
• Wear suitable personal protective equipment for all work on the device.
• Select correct measurement points.
WARNING
Danger to life due to electric shock
Under fault conditions, when working on the power supply circuit there may be dangerous voltages present on the
product. This can result in death or serious injury.
• For power supply units with a fixed connection, make sure that a disconnection unit (e.g. miniature circuit
breaker) is present outside the power supply unit.
• For power supply units with a plug connection, make sure that the electrical outlet for the power supply unit is
close to the power supply unit.
• The disconnection unit and the electrical outlet for the power supply unit must be freely accessible at all times.
