Important! … X-Ray Protection
Please strictly observe the protective measures; otherwise the X-ray
equipment shall hurt the patients and the operators.
The X-ray equipment shall cause the injury in the event of improperly operation.
Therefore, please read the instructions carefully and fully understand them before
the equipment is brought into service. We are willing to help and coordinate with
you to put the equipment into service.
Although the equipment produced on the basis of the strict safety standards can
provide the effective protection of X-ray radiation and the useful beamline protection,
actually, no equipment can provide the complete protection, and further more, no
equipment can force the operators to take the adequate protective measures to prevent
oneself or other people from being exposed in the X-ray radiation due to the negligence,
rashness and involuntary of the operators.
Importantly, all operators who operate the X-ray equipment should be properly
trained, and the proper protective measures should be applied to avoid the hurt. The
manufacturers consider that all operators and maintainers who are authorized to use,
install, regulate and maintain the equipment have already known the hazard of the
immoderate exposure in the X-ray and received the sufficient training and grasped the
related knowledge. The manufacturers, agents and sales representatives are not
responsible for any injury and damage caused by exposure in the X-ray.
All kinds of protective materials and equipments can be obtained in market and the
clients are proposed to use these kinds of materials and equipments.

Chapter 3 Installation instruction
This equipment can only be installed and tested by the manufacturer or other
personnel authorized by the manufacturer.
3.1 Field requirement
Field area should not be less than 50 ㎡ in principle. The room, with the narrowest
location not less than 4m, should be divided into operating room and control room, and
lead protective measures should be accordance with local requirement. For this
equipment is a mobile Unit, the ground should be leveled without doorsill at the joint
between rooms to facilitate free access of the equipment through the door with a width of
90cm..
The power supply required by the overall system is single phase AC with frequency
of 50Hz±1Hz, capacity no less than 3.5kW. Ask for 16A three-core inlet, rated voltage of
220V±10% and source resistance not higher than 0.6Ω. The power supply should be
grounded securely with earth resistance not higher than 4Ω. (Criteria for ground wire: a
metal rod buried to a depth of 1m underground with salt and carbon powder sprinkled
around and tamped.)
If the power level is at 220V with no X-Ray emission and drops more than 3V (for
example, if Tube V/A at 70KV/3mA) with X-Ray emission, this indicates that the power
source doesn’t supply sufficient power and a 5kW or above AC voltage stabilizer needs to
be installed (should be equipped with a reliable brand).
Supply the equipment with an independent power source is mandatory since shared
power source might cause severe electromagnetic interferences impacting normal
performance of the X-Ray equipment.

Power plug ground wire must be connected to Earth ground.
Connect to temporary or low capacity power supply is strictly prohibited. Sharing
power source with other load bearing equipment (such as soldering machine etc.) is also
not recommended.
The equipment should be stored only at no-direct sunlight, dry, humidity-controlled and
well ventilated indoors. Direct contact with ground dirt should be strictly avoided.
Weather-resistant measures must be taken for temporary storage at all times.
3.3 Unpacking and Inspection
Unpack; check packed items according to the packing list. Make sure all parts are in
good condition. In case, there is any damage found, please contact the manufacturer
immediately for handling.
12
Mobile C-arm X-ray System Service Manual
Note: Use a box opener to unpack the upper case first and than the side covers at
last remove the fix objects.
z Check whether the accessories are complete and in perfect conditions after
unpacking.
z Please contact your supplier immediately if any accessory is incomplete or
damaged.
z The list of accessories depends on your purchase contract.
Note: Please reserve the packaging material for future reuse in transporting the
instrument.
The installation must be performed in accordance with technical data. Upon
completion of installation, make sure all protection ground wires provided by the
manufacturer are securely connected and protective covers are installed and fixed with
screws before turning on the power of the equipment.
3.4 Installation
3.4.1 Mechanical Movement and Brake Function Test
1. Push the equipment to check for its flexibility and smoothness of movement. Ensuring
it can be tightly locked. Run test on its movements to ensure there is no block in glide of
C-arm along arc, 200m range of forward/backward movement, 12.5° range of left/right
sway, rotation around horizontal axis, etc.
2. Braking mechanism: firstly open the rear cover of X-ray unit, wrap terminal L and N
with insulation tape to avoid occurrence of short circuit between terminals or between
terminal and floor, shown as follows:
13
Mobile C-arm X-ray System Service Manual
3. Connect power supply (220V AC) with the power line, press “Power ON” button and
then press “Brake” button as shown in the following figure. Now the equipment is braked
automatically. Confirm whether the equipment is braked completely by pushing it gently.
And switch off power and remove power line.
3.4.2 Install image intensifier
1. Release the handrails for C-arm circular arc movement, adjust C-arm to proper
position for convenient installation of image intensifier and then lock the locking handrails
again.
2. Take out image intensifier from package box and check whether there is any
appearance damage. Remove the six pieces of mounting screws supplied with image
intensifier connecting plate by using inner hexagon wrench, as shown in the following
figure.

of C-arm, and fix them with mounting screws supplied with the equipment.
Note: At least two persons are needed to avoid personal injury or device damage
caused by the drop of image intensifier
Keep the edge of connecting plate parallel to the one of mounting plate to assure
precision of image intensifier. mounting position.
4. Take out CCD camera from the package box, and detach the cover base to take CCD
camera out.
5. Remove the blue plastic dust-proof cover for output screen from the bottom of image
intensifier, and check whether there is dust on the output screen. Blow away the dust with
blowing balloon if any. The cleanness within this region is extremely important as the
image intensifier output screen is the focal plane for imaging.

6. Remove lens cover of camera, align mounting holes of camera to the ones at the
bottom of image intensifier and fix with three pieces of screws.
Note: Rotate both CCD and image intensifier clockwise until an included angle is
presented up to 90°for installation and fixing.
