Fundamental safety instructions for the SIMOTICS documentation
1.1 Fundamental safety instructions
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,
• Do not use any damaged motors or devices.
Electric shock due to unconnected cable shield
Hazardous touch voltages can occur through capacitive cross-coupling due to unconnected
cable shields.
• As a minimum, connect cable shields and the conductors of power cables that are not
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.
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
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
