3-2 System Preparation
CAUTION:
1. Maintain a generous – free air flowing space around the back and both
sides of the system; failure may result due to increased rise in system
operating temperature.
2. Pay extra attention when moving the system on a sloping ground, do not
move it on a more than 5°-sloped plane to avoid system toppling.
3.2 Connecting Power Cord & Protective
Grounding
This system can work when it is connected to the external power supply or the battery capacity is
sufficient.
When the system is powered by the batteries, self-test is not supported.
3.2.1 Connecting Power
The connection method is described as follows:
1. Plug the power cable in the socket of the ultrasound system.
2. Plug the other end power plug into an appropriate outlet. The grounding terminal should be
connected with a power grounding cable to ensure that protective grounding works normally.
NOTE: Make sure to allow sufficient slack in the cable so that the plug is not pulled out of the wall
if the system is moved slightly. If the plug is pulled out accidentally, data may be lost.
3.2.2 Powered by Battery
The battery can support the ultrasound system for normal working for no less than 90 minutes.
When connected to the external power supply, the system is powered by the external power. The
batteries inside it are in the charging status.
When disconnected from the external power supply, the system is powered by the batteries. Refer
to Appendix F Battery” for the detailed operations and precautions.
3.2.3 Equipotential terminal
The symbol represents the equipotential terminal that is used for balancing the protective earth
potentials between the system and other electrical equipment.
