 10.2 CE Marking 
At Sanyo Denki, we are executing tests on the PY2 Servo Amplifier for compliance with the CE marking 
at qualifying institutions.    The CE mark is required to be attached all end products sold in EU countries.   
Only products conforming to the safety standards are permitted to have them.  Accordingly, customers 
are requested to perform the final conformity test on their machines or systems incorporating our 
amplifiers.

10.2.3  Structure of the Control Panel 
1.  A metallic material is used for the control panel and its cover. 
2.  The joint of the roof and the side board shall be masked and welded. 
3.  The joint fixed with screws shall be welded to prevent noise from leaking from the gap in the joint. 
4.  In case of fixing with screws or spot welding, the welding space shall be within 10 cm. 
5.  Use an EMI gasket to prevent clearance between the cover and the control panel.

7.  Perform wiring from the secondary side of the noise filter to the Servo Amplifier, keeping it as short as 
possible. 
8.  The wiring for the primary and secondary sides of the noise filter must keep a certain distance apart.
