WARNING
Electric shock due to damaged motors or devices
Improper handling of motors or devices can damage them.
Hazardous voltages can be present at the enclosure or at exposed components on damaged
motors or devices.
● Ensure compliance with the limit values specified in the technical data during transport,
storage and operation.
● Do not use any damaged motors or devices.
WARNING
Electric shock due to unconnected cable shields
Hazardous touch voltages can occur through capacitive cross-coupling due to unconnected
cable shields.
● As a minimum, connect cable shields and the cores of cables that are not used at one end
at the grounded housing potential.
WARNING
Electric shock if there is no ground connection
For missing or incorrectly implemented protective conductor connection for devices with
protection class I, high voltages can be present at open, exposed parts, which when touched,
can result in death or severe injury.
● Ground the device in compliance with the applicable regulations.
WARNING
Arcing when a plug connection is opened during operation
Opening a plug connection when a system is 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.
WARNING
Electric shock due to residual charges in power components
Because of the capacitors, a hazardous voltage is present for up to 5 minutes after the power
supply has been switched off. Contact with live parts can result in death or serious injury.
● Wait for 5 minutes before you check that the unit really is in a no-voltage condition and
start work.
