Preparation for Installation

3.1

Precautions Regarding Installation

The place where the machine is to be installed needs to meet the criteria set forth in "Getting
Started" and "3.1.1 Installation Site Requirements." Preinstallation procedures should be
performed beforehand for necessary construction work, electrical work, and air-conditioning
system installation.
3.1.1 Installation Site Requirements
Avoid the following installation sites:
- Places where the temperature changes drastically.
- Places near heat sources such as heaters.
- Places where water leakage or equipment submersion may occur.
- Places where corrosive gas may be generated.
- Dusty places.
- Places where the machine is subject to constant or excessive vibration or shock.
- Places that are exposed to direct sunlight.
- Places that are exposed to X-rays while the machine is processing.
Make sure that the machine will never be exposed to direct and scattered X-rays while the
machine is processing.
The size and position of the X-ray shields should be such that the machine is completely
shielded to avoid exposure of direct and scattered X-rays to the machine.
 When installed in the patient environment
In the room where the machine is to be installed, the hospital-grade grounding terminal and
outlet should be provided.
The installation place should be within reach of the cable of the patient environment support
cable kit from the hospital-grade grounding terminal and outlet.
 When installed in other than the patient environment
Make sure that persons other than routine operators of the machine will not touch the
machine inadvertently.

3.1.2 Precautions on Patient Environment
 Additional Protective Grounding
If the RU is installed in the patient environment with the connected equipment in the non-
medically used room, the additional protective grounding will be required.
Definitions of "patient environment", "medically-used room", and "non-medically used room"
are given below.
 Patient Environment
Patient environment is the area for the patient to receive medical procedures (treatment,
tests, diagnosis, monitoring).It is the space measuring 2.5 m in all four directions and 2.5 m
in height from the area of the patient's body. It excludes the space traveled by the patient to
reach the medically-used room.
 Medically-Used Room
Room equipped with protective grounding (medical use outlet or medical use grounding
terminal) implemented by the medical grounding method. The protective grounding inside
the medically-used room is equipotential, and the protective grounding of this medically-
used room is equipotential to that in the other medicallyused room. Generally, a portion of the
medically-used room is the patient environment.
 Non-Medically Used Room
Areas outside the medically-used room are considered the non-medically used room.
3.1.3 Handling Precautions for Printed Circuit Boards and Optical
Unit
When servicing a board or optical unit, use a wristband to ground your body.
If you body is not grounded, the electrostatic buildup on your body may damage the
electronic parts.
3.1.4 Precautions for System Connection
"Accessory equipment connected to be the analog and digital interfaces must be certified
according to the respective IEC Standards. Furthermore all configurations shall comply with
the medical system standard, IEC60601-1-1. Everyone who connects additional equipment
configures a medical system, and is therefore responsible that the system complies with
the requirements of IEC60601-1-1. If in doubt consult with the your local technical service
representative."
