3-2 System Preparation
3.2
Connecting Power Cord & Protective
Grounding
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
Equipotential terminal
The symbol
represents the equipotential terminal that is used for balancing the protective earth
potentials between the system and other electrical equipment.
WARNING:
1.
Be sure to connect the equipotential wire before inserting the
power plug into the receptacle;be sure to pull out the power plug
from the receptacle before disconnecting the equipotential wire;
otherwise electric shock may result.
2.
When you connect another device to this system, you should use
the equipotential wire to connect each of equipotential terminals;
otherwise electric shock may result.
3.
Connect the earth cable before turning ON the system. Disconnect
the earth cable after turning OFF the system.Otherwise, electric
shock may result.
4.
DO NOT connect this system to outlets with the same circuit
breakers and fuses that control the current to devices such as
life-support systems.If this system malfunctions and generates
overcurrent, or when there is an instantaneous current at power
ON, the circuit breakers and fuses of the building’s supply circuit
may be tripped.
