Safety instructions for Braking Modules Booksize

Danger to life if the fundamental safety instructions and remaining risks are not carefully
observed
If the fundamental safety instructions and remaining risks in Chapter 1 (Page 25) are not
observed, accidents involving severe injuries or death may occur.
• Adhere to the fundamental safety instructions.
• When assessing the risk, take into account residual risks.
Fire hazard due to overheating because of inadequate ventilation clearances
Inadequate ventilation clearances can cause overheating with a risk for personnel due to
smoke and fire. This can also result in increased failure rates and a shorter service life of
the components.
• Maintain the 80 mm clearances above and below the components.
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.
