3. PreparationforInstallation
3.1 PrecautionsRegardingInstallation
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 InstallationSiteRequirements
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.
lWheninstalledinthepatientenvironment
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.
lWheninstalledinotherthanthepatientenvironment
Make sure that persons other than routine operators of the machine will not touch the
machine inadvertently.
3.1.2 PrecautionsonPatientEnvironment
nAdditional 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.
Denitionsof"patientenvironment","medically-usedroom",and"non-medicallyused
room" are given below.
lPatient 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.
lMedically-UsedRoom
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 medically-
used room.
Generally, a portion of the medically-used room is the patient environment.
lNon-MedicallyUsedRoom
Areas outside the medically-used room are considered the non-medically used room.
3.1.3 HandlingPrecautionsforPrintedCircuitBoardsand
OpticalUnit
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 PrecautionsforSystemConnection
"Accessory equipment connected to be the analog and digital interfaces must be
certiedaccordingtotherespectiveIECStandards.Furthermoreallcongurations
shall comply with the medical system standard, IEC60601-1-1. Everyone who
