Safety information

Not observing fundamental safety instructions and residual risks
Not observing fundamental safety instructions and residual risks listed in Chapter 1 can
result in accidents with severe injuries or death.
• Comply with the fundamental safety instructions.
• When assessing the risk, take into account remaining risks.
Fire and device damage as a result of ground fault/short-circuit
Inadequate installation of the cables to the braking resistor can result in a ground
fault/short-circuit and place persons at risk as a result of the associated smoke and fire.
• Comply with local installation regulations that enable this fault to be ruled out.
• Protect the cables from mechanical damage.
• In addition, apply one of the following measures:
Fire due to overheating when the total length of the connecting cables is exceeded
Excessively long Braking Module connection cables can cause components to overheat with
the associated risk of fire and smoke.
• The Braking Module connecting cables may not be longer than 100 m.
NOTICE
Damage through the use of non-released braking resistors
Braking resistors can be damaged when using braking resistors other than those specified in
this Manual.
• Only use braking resistors released by Siemens.
