ELECTRICAL PRE-INSTALLATION
The Orthoralix requires a fixed electrical installation.
The mains cable required is two poles with ground (not supplied).
The mains cable inlet is at the rear of the column, and is provided
with cable retainer.
Therefore a suitable outlet shall be provided on the wall behind the
column, from where the mains supply cable has to be derived.
The remote control box is connected to the Z-carriage by a 20 m
cable.
The cable inlet is at the rear of the column.
The mains supply cable has to be connected to the mains circuit
connection points, accessible at the front of the column.

4.5.
X-RAY PROTECTION
The machine is intended for (indoor) dental practice without special
X-ray protection in walls, floors and ceilings.
X-ray protection comes from the distance to be kept from the unit,
proper X-ray beam collimation and inherent shielding implemented
in the machine.
Primary X-ray beams are shielded by a lead plate, located in the
rear of the cassette unit (thickness:1.5 mm in Pan and Transcan,
1 mm in Ceph mode).
In the DDE versions, the X-ray beams are shielded by the sensor
assembly, introducing a filtration equivalent to 1.5 mm of lead.
