2  System Connection 
This chapter introduces how to connect the power supply, equipotential terminal, transducers 
and peripherals to the system. 
NOTE:  Before connecting the system, put the system in a proper place and 
ensure at least 20cm of clearance at the back and sides of the system. 
The transportation, storage and operating environments of the system 
must meet requirements listed in the appendix. Besides, store and use the 
system in a clean location where there is no direct sunlight, no sudden 
changes in temperature, no condensation, few dust, no vibration, and far 
from heat generators. 
2.1    Connecting Power Supply 
Connect the power plug of the system to an outlet meeting the following requirements: 
Voltage: 100-240V~ 
Frequency: 50/60Hz 
Input current: 1.0-0.5A 
 
WARNING: 
1.  Do not connect the system to outlets with the same 
circuit breakers and fuses that control current to devices 
such as life-support systems. If the system malfunctions 
and generates an 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.
2.  Do not connect the three-wire power cable of the 
machine to a two-wire plug without grounding protection 
phase, otherwise electric shock may happen. 
3.  Use the power input cord as the power breaking facility 
of the system. 
2.2    Connecting Equipotential Terminal 
When the system is connected with other equipments such as printers, be sure to connect the 
equipotential terminal of the system and those of other equipments with lead wire.
