DANGER
Potentially lethal shock hazard!
It is essential to switch the unit off and to wait at least 1 minute, or 4
minutes if disconnecting the tube assembly (cable L3), before starting
the repair or taking off a cover panel!
When replacing parts in the vicinity of the power connection, power
switch, board DX32 or X-ray tube assembly, the unit must be
disconnected from the junction box of the main building!
CAUTION
Make sure to reattach all ground cables to ensure correct grounding of
all modules.
CAUTION
Product safety
Modifications to this unit which might affect the safety of the system
owner, patients or other persons are prohibited by law! For reasons of
product safety, this product may be operated only with original Sirona
accessories or third-party accessories expressly approved by Sirona.
The user is responsible for any damage resulting from the use of non-
approved accessories.
NOTICE
Do not damage the cables
Be careful not to kink the cables when removing or installing them. Take
particular care with fiber-optic cables L5, L6, L7, and L15. Tighten cable
ties only as far as the contact and do not apply force.
NOTICE
Risk of damage to boards
Please observe the usual precautionary measures for handling printed
circuit boards (ESD). Touch a ground point to discharge static electricity
before touching any boards.
IMPORTANT
After replacing boards or modules containing boards, check to make
sure that the software version of the module corresponds to the current
software status of the system. The software versions of the modules can
be queried by running service routine S008.2 or using the extended
detail query in SiXABCon. You can also check the info screen in
advance to determine whether the current software constellation is
permissible. If this is not the case, the version number of the entire
software is labeled with an asterisk (e.g. V03.03.01*).
