NOTICE
Device failure as a result of unshielded or incorrectly routed cables to braking resistors
Unshielded or incorrectly routed cables to braking resistors can result in interference being
coupled into the signal processing electronics from the power side. This can result in
significant disturbance of all signals (fault messages) up to failure of individual components
(destruction of the devices).
• Only use shielded cables for cables to braking resistors.
NOTICE
Danger to life through the use of non-approved braking resistors
Braking resistors can be damaged when using braking resistors other than those specified
in this Manual.
• Only use braking resistors approved by Siemens.
