WARNING
Electric shock due to unconnected cable shield
Hazardous contact voltages can occur as a result of capacitive cross-coupling due to
unconnected cable shields.
• Connect cable shields and unused cores of power cables (e.g. brake cores) at least on
one end at the grounded enclosure potential.
WARNING
Electric shock if there is no ground connection
When the ground connection of devices with protection class I is missing or incorrectly
implemented, 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 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.
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.
NOTICE
Property damage due to loose power connections
Insufficient tightening torques or vibration can result in loose power connections. This can
result in damage due to fire, device defects or malfunctions.
•
Tighten all power connections to the prescribed torque.
• Check all power connections at regular intervals, particularly after equipment has been
transported.
