Hitachi Microscope & Magnifier S-4800 Manual De Usuario

PRECAUTION - 1  

For the sake of safety, the following points should be taken into consideration. 
 
1.  PRECAUTIONS FOR TRANSPORT 
 

(1)  Do not lift the instrument by holding the table.    The strength of table fitting is not sufficient 

for bearing the weight of display unit, approximately 200 kg.    Should the table be lifted, the 
display unit might slip off and crash.    Hence, it is recommended to remove the table and 
transport the display unit independently when moving the instrument. 

 
(2)  The housing supports should be fitted in place before transport. 
 
 
2.    PRECAUTIONS FOR POWER CONNECTION   
 

(1)  When removing the front, rear and top covers of housing and display unit, turn off the AC 

power.    The high voltage circuit within the unit constitutes a shock hazard. 

 
(2)  Connect the grounding wire correctly.    Otherwise, not only will the instrument fail to 

operate normally but there is a shock hazard. 

 
(3)  Avoid touching the connector of high voltage unit and the cable head of high voltage 

transformer.    The high voltage unit and the high voltage transformer are at voltages as 
high as 30 kV, so handling of dangerous parts such as high voltage connector and cable 
head should be left to the service engineer. 

 
(4)  Do not touch the areas marked HAZARD.    These areas are supplied with high voltage. 
 
(5)  When replacing a fuse, turn off the main switch on the distribution board and make sure 

that the AC power supply is cut off.    If not the AC power line near the fuse box may cause 
shock.
