Identification of warning notes
This symbol indicates hazards that could lead to personal injury.
There are three signal words indicating the severity of a potential injury.
DANGER
Indicates a hazard with a high risk level. If this hazardous situation is not avoided, it will result in death or serious injury.
WARNING
Indicates a hazard with a high risk level. If this hazardous situation is not avoided, it will result in death or serious injury.
CAUTION
Indicates a hazard with a low risk level. If this hazardous situation is not avoided, it could result in minor or moderate injury.
This symbol together with the NOTE signal word warns the reader of actions that might cause property damage or a malfunction.
Here you will find additional information or detailed sources of information.

Safety notes
WARNING: Risk of death due to electric shock
Only use external current transformers with reinforced or double insulation.
Install current transformers and corresponding measuring devices only when the power supply of the system is disconnected.
- The device is protected by double insulation or reinforced insulation.
- Installation should be carried out as described in the installation notes. Accessing circuits within the device is prohibited.
- Always disconnect the device from the energy supply before performing any work on it. Short-circuit the secondary side of each current transformer.
- Use an appropriate voltage measuring device to ensure that no voltage is present.
- Re-install all the equipment, doors, and covers on the device before switching on the device again.
- Ensure that the control cabinet is grounded in accordance with DIN EN 61439-1.
- Ensure that the control cabinet door in which the device is installed is grounded.
- Provide a switch/circuit breaker close to a device, which is marked as the disconnecting device for this device.
- Provide overcurrent protection (≤16 A) for the supply voltage within the installation.
- To protect the device against mechanical or electrical damage, install it in a suitable housing with an appropriate degree of protection in accordance with IEC 60529.
- If the device is not used as described in the documentation, the provided protection may be impaired.
- The device is maintenance-free. Repairs may only be carried out by the manufacturer.
- The device must be stopped if it is damaged, was subjected to an impermissible load, stored incorrectly or if it malfunctions.
- Check that the measuring device is working correctly by measuring a known voltage and a known current.
- Ground each current transformer on the secondary side.
- Never short-circuit the secondary side of the voltage transformer.
- Note the measurement voltage stated on the device rating plate when selecting and connecting the voltage transformer.
