Protective measures
It is very important that any intervention in the equipment shall start with disconnecting it
from the power supply with the main circuit breaker. To prevent accidental triggering of
high voltage and radiation, set the switch S2 (SS) on board D702 to OFF (lower position,
no triggering of the SS relay).

When switching off the workstation use the power off procedure
described in the Supplement to the Instructions for Use MAMMO-
MAT 3000 - Opdimar.
Switching off the workstation before the software has been
closed down may cause damage to the files on the hard disc.
If the system is only switched off at the control panel or with S2/
D711 in the MAMMOMAT generator, line voltage will still be
present at the generator line connection, line filter Z1, Z2, trans-
former T1, transformer T10 and board D711 (see MAMMOMAT
1000/3000 Nova Wiring Diagram). The Opdimar is switched off
separately.
After shut-down of the system, there may still be about 380 V DC
present on the intermediate circuit of the MAMMOMAT generator.
This will be indicated by LED V24 on board D710. The voltage will
drop to less than 30 V within about 3 minutes, the LED goes out at
about 30 V.
Observe the currently valid guidelines for handling electronics
endangered by electrostatic discharge.
Use ESD-equipment, ground prior to making contact and place
the components on a conductive surface.
The boards contain electrostatic highly sensitive components
requiring particular care in their handling.
Risk of damaging components.
