Safety information
WARNING
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 21) 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.
DANGER
Danger to life due to electric shock in the event of missing touch protection
Death or serious injury can result when live parts are touched.
• For the reactor, use touch protection according to IPXXA or corresponding to the local
installation regulations.
NOTICE
Damage caused by line reactors which are not approved for the SINAMICS S120 Combi
The following can occur if line reactors are used that have not been approved for
SINAMICS S120 Combi by SIEMENS:
- The infeed in the S120 Combi may be damaged or destroyed.
- Line harmonics may occur that damage or destroy loads connected to the same line
supply.
• Only use line reactors which are listed in this Manual.
NOTICE
Damage due to high temperatures of line reactors
The surface temperature of the line reactors may exceed 80°C. This can lead to
temperature-related damage to adjacent components.
• It is absolutely essential that you maintain clearances according to the table Ventilatio
n
c
learances above and below the component (Page 310) around the reactor.
• If this clearance cannot be observed, additional measures such as shielding plates or
a
c
ooling system must be provided.
NOTICE
Faults due to the magnetic fields of line reactors
Reactors generate magnetic fields. Components and cables can be damaged or affected
by this.
• Ensure there is sufficient clearance (at least 200 mm) from the reactors or shield them.
