WARNING
Electric shock due to unconnected cable shields
Hazardous touc
h 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
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 t
he capacitors, a hazardous voltage is present for up to 5 minutes after the power
supply has been switched o. 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
Damage to equipment due to unsuitable tightening tools.
Unsuitable tight
ening tools or fastening methods can damage the screws of the equipment.
• Only use screw inserts that exactly match the screw head.
• Tighten the screws with the torque specied in the technical documentation.
• Use a torque wrench or a mechanical precision nut runner with a dynamic torque sensor and
speed limitation system.
• Adjust the tools used regularly.
WARNING
Electromagnetic interference due to inadequate shield support
A lack of adequat
e shield support for the power cables can cause malfunctions and
impermissibly high levels of interference.
• Use the shield connection plates supplied or recommended.
• Use the shield connection clips recommended.
