WARNING
Non-observance of the fundamental safety instructions and residual risks
The non-observance of the fundamental safety instructions and residual risks stated in
Chapter 1 can result in accidents with severe injuries or death.
•
Adhere to the fundamental safety instructions.
•
When assessing the risk, take into account residual risks.
WARNING
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:
–
Use cables with double insulation.
–
Maintain adequate clearance, e.g. by using spacers.
–
Lay the cables in separate cable ducts or conduits.
WARNING
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.
WARNING
Fire through overheating due to insufficient ventilation clearances
Inadequate ventilation clearances can cause overheating with a risk for personnel through
smoke development and fire. This can also result in increased failures and reduced service
lives of braking resistors.
•
It is essential that you maintain a ventilation clearance of 200 mm on all sides of the
component with ventilation grilles.
