Description
9 Switchgear maintenance
Maintenance 8DJH switchgear is maintenance-free under normal ambient conditions according to
IEC 62271-1. Inspection or testing of the secondary equipment such as the capacitive voltage
detecting system is done within the scope of locally applicable laws and regulations.
Checking the dew point The dew point needs no checking throughout the entire service life.
Checking the gas quality The gas quality needs no checking throughout the entire service life.
Test operation A function test of the switching devices is required only at the time of commissioning,
modification or retrofit at the panel.
Replacement of
components
Due to the fact that all parts of this switchgear have been optimized to last the normal service
life, it is not possible to recommend particular spare parts.
Information required for spare part orders of single components and devices:
• Type and serial number of the switchgear (see rating plates)
• Description or identification of the device or part on the basis of a sketch, a photo or a circuit
diagram
10 End of life
SF
6
gas
Before recycling the materials, evacuate the SF
6
gas professionally and prepare it for further
use. For further information, please contact the Siemens Service Hotline.
Recycling The switchgear is an environmentally compatible product.
The components of the switchgear can be recycled in an environmentally compatible way by
dismantling into sorted scrap and residual mixed scrap.
After evacuating the SF
6
gas, the switchgear mainly consists of the following materials:
• Steel (enclosure and operating mechanisms)
• Stainless steel (vessel)
• Copper (busbars)
•Silver (contacts)
• Cast-resin based on epoxy resin (bushings and post insulators)
• Plastic materials (switching devices and fuse tripping)
• Silicone rubber
The switchgear can be recycled in ecological manner in compliance with existing legislation.
Auxiliary devices such as short-circuit indicators have to be recycled as electronic scrap.
Any existing batteries have to be recycled professionally.
As delivered by Siemens, the switchgear does not contain hazardous materials as per the
Hazardous Material Regulations applicable in the Federal Republic of Germany. For operation
in other countries, the locally applicable laws and regulations must be observed.
For further information, please contact the Siemens Service Hotline.
NOTE
The equipment contains the fluorinated greenhouse gas SF

. SF
6
has to be reclaimed and must not be
released into the atmosphere.
➭ For use and handling of SF
