Appendix 1. Additional Protective
Grounding
Additional protective grounding will be required if installing this equipment in the
patient environment with the connected equipment in a non-medically used room.
Refer to Medical System Standard, IEC60601-1-1.
However, there may be cases where additional protective grounding is not possible.
(For example in cases like non-metallic faceplate screws as well as boxes and
isolated supply systems etc.) If this should happen, please refer to “Counter-measures
for additional protective grounding” on the next page.
This installation work should only be performed by persons certified to handle
electrical facility construction.
Definitions of “patient environment”, “medically-used room”, and “non-medically used
room” are given below.
l
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.
l
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
medically-used room.
Generally, a portion of the medically-used room is the patient environment.
l
Non-Medically Used Room
Areas outside the medically-used room are considered the non-medically used room.
n
Connection Locations of Cables for Additional Protective
Grounding of the Equipment and Clamp Locations
<INSTRUCTIONS>
Please use power supply cord and clamp (which is required for keeping the additional
protective ground cord in position) approved by the electrical standard of the country
to which the equipment is to be installed.
<Counter-measures for additional protective grounding>
1. Engage the services of a professional to make the necessary preparations for the
connection of additional protective grounding.
2. If the connected device possess a hospital grade earth terminal and is mobile,
move the connected device and replace with a power supply plug which has
hospital grade earth terminal.
3. Install a isolating transformer to the connected device. In this way, the power supply
from the connected device will be separated from the main power supply.
