Arcing when a plug connection is opened during operation
Opening a plug connection when a system is in operation can result in arcing that may
cause serious injury or death.
• Only open plug connections when the equipment is in a voltage-free state, unless it has
been explicitly stated that they can be opened in operation.
Risk of fire due to usage of an unsuitable power supply.
When equipment is connected to an unsuitable power supply, components may overheat.
That might result in ignition of fire.
• Only use power supplies with limited energy (LPS) for all connections and terminals of the
electronics modules.
Burn injuries caused by hot surfaces
In operation, devices can reach high temperatures, which can cause burns, if touched.
• Take measures, when maintenance is required.
• Allow the device to cool down before starting any work.
• Use the appropriate personnel protection equipment, e.g. gloves.
