4 WARNINGS AND CAUTIONS
The following safety precautions must be observed in order to avoid the risk of
personal injury or damage to the X-ray unit.
RADIATION SAFETY RULES
Some procedures described in this manual produce X-ray radiation. Always follow
the rules for radiation protection.
Never attempt to open the TUBE HEAD. It does not contain any serviceable parts,
and radiation safety can no longer be guaranteed.
Never take exposures without filter or beam limiting device (collimator) in place.
Otherwise radiation safety cannot be guaranteed.
ELECTRICAL SAFETY RULES
The X-ray unit contains hazardous voltages. While servicing internal parts, always
disconnect the X-ray unit from the mains power supply
- by turning the external mains switch to the off position (permanently installed X-ray units)
or
- by removing the plug from the wall outlet (X-ray units with a detachable power supply
cord).
Wait for 2 minutes before touching any electrical parts.
Turning off the X-ray unit from its own mains switch does not cut off the mains
voltage from the mains terminal.
Always replace the fuses with those of the same type and rating. Otherwise patient,
operator or equipment safety cannot be guaranteed.
The circuit boards can be damaged due to static discharges and require careful
handling.
Do not connect items which are not specified as part of the system.
Do not connect a multiple portable socket outlet (MPSO) or an extension cord to the
system.
The X-ray unit must be connected to a dedicated, protectively grounded power line
(no other devices are connected to the same power line).
If the X-ray unit is not connected to an Uninterruptible Power Supply (UPS), switch
the X-ray unit off during lightning storms.
