1.5 Text emphasis
DANGER
WARNING
CAUTION
NOTICE
NOTE
DANGER indicates when there is an immediate danger that leads
to death or serious physical injury.
WARNING indicates a risk of danger that may lead to death or to serious
physical injury.
CAUTION used with the safety alert symbol indicates a risk of danger that
leads to slight or moderate physical injury and/or damage to property.
NOTICE used without the safety alert symbol indicates a risk of danger that if
disregarded leads or may lead to a potential situation which may result in an
undesirable result or state other than death, physical injury or damage to
property.
NOTE contains information provided with special emphasis to facilitate proper
use of the equipment or proper execution of a procedure, i.e. hints, tips.

1.6 Safety Information and Preventive Measures
CAUTION
• When completing repair work and tests, please note:
- the product-specific safety information in the document,
- the safety information in TD00-000.860.01….
• If the system is only switched off at the control panel, line voltage is
present at: Mains input terminal blocks; Fuses F1, 2, 3, 4, 5, 6, 7, 8, 9, 10,
11, 12; Main contactor TLR1 and emergency cut off buttons PB2 and PB3;
Line filter FL1; PCB 03-186 and related parts (solid state relay RY1, resistor
R1).
• Voltage higher than 60Vac is present on: Terminal M3; Transformers
TF155, TF165 and their connected parts; C-arm driving gear motor MT1
and limit switches MW1, MW2; Rotating anode starter 92-074 and
capacitors C5, C6; Tube Rotating Anode Cable and supply connections.
• After shut dow n, there may still be dangerous voltage up to 550Vdc on
inverter power supply. Voltage decreases to zero by means of bleeder
resistors in not less than 5 minutes due to capacitor size, energy stored is
still dangerous if short to ground occurs when It’s less than 60Vdc and till
when capacitors are not fully discharged: Rectifier bridges PD1, PD2;
Capacitors block C1, 2, 3, 4; Inverter block and electrical connection to
High Voltage generator
• High-voltage 20 ÷ 35 kV is present on: High Voltage generator; High
voltage cable; X-ray tube.
• Use ESD precautions for handling Printed Circuit Boards containing ESD
sensitive components.
• To prevent accidental triggering of High Voltage and X- Radiation output xray pushbutton has Dead Man function by which H.V. generator is
disconnected by CPU if push button is not intentionally pressed. For more
safety during intervention: 1) DEMO MODE can be selected by means of
DIP 3 SW1 PCB 01-170. 2) Fuses F6, F9 can be removed and Inverter
voltage monitor disabled by means of DIP2 SW2 set to ON. Vdc across
C1,2,3,4, inverter and H.V. transformer will be zero after discharging time.
• Tests or adjustments that must be made with radiation switched on are
identified with the radiation warning symbol .
During these types of adjustments, radiation protective clothing must be
worn.
