Electrical voltage!
See (Safety information / p.
Prior to removing the mini-voltage supply, the system
must be switched off for at least 3 minutes, until the
high voltage in the system and in the I.I. mini-voltage
supply dissipates.
Risk of injury on mechanical parts!
If these guidelines are not followed, minor to moderate injury,
especially to the hands, can occur.
Follow the notes concerning the C-arm carbon fiber
structure.
Risk of injury!
Noncompliance can lead to minor to medium injury
and/or property damage.
The C-arm covers contain counterbalance weights and
weigh approx. 6 kg. Hold the covers firmly when install-
ing or removing them.
Before the C-arm cover is loosened, the C-arm must be
moved to its middle orbital position. If the C-arm cov-
ers are loosened, the C-arm may not be moved to its
orbital end positions (I.I. or SIREPHOS at the orbital
end position).
Rotate the camera into the 0° position prior to beginning
work to avoid having to readjust the camera rotation.
The cathode wire on the image intensifier (black wire con-
nected to plug CON1.8 on the controller) is fairly short in
some locations.
The cathode wire can be extended for easier access to the
measuring points and potentiometer on the controller. To
extend the wire, split the wire and strip off the insulation from
the wire ends.
Place two pieces of appropriately sized shrink tubing over
the wire ends. Solder an approximately 25 cm wire to 0.75
square mm. Insulate the wire ends with the shrink tubing.
