Special Warning 

   

In order to ensure the protective performance of the case of the whole electric actuator, 

users must strictly follow the requirements in the 

Operation Manual

 and in this 

Special 

Cautions

 while performing relevant operations when they set and service the actuators. If 

users failed to follow the regulations in the 

Operation Manual

 and the 

Special Cautions

 while 

performing relevant operation and have resulted in fail-safe protection of the case of the 
electric actuators, the users shall bear the responsibility. 
 

Before delivery all locations related to case protection of the products have been strictly 

inspected to ensure that the case is airtight. If users need to open the following locations for 
setting, service or any other reasons: 
 

1.Case of control box 
2.Case of wiring box 
3.Wire outlet plug 
At places where wire comes in and goes out, it must be ensured that: 

1. There is no affect of adverse elements such as rain, snow, hail, damp and dust, etc. as the 
electric actuator will lose original protection function in the above conditions. 
2. At the end of operation, replace the cover. When fastening the clamp nuts at wire inlet and 
outlet, make sure that no adverse elements (such as severe damp, water and dust, etc.) that 
could weaken protective performance left in the inner space.   
3. In the course of mounting covers, make sure that rubber seal rings are not damaged and 
fasteners are securely screwed down without any omission. 
4. After cable comes out of connecting sleeve, securely fasten the clamp nuts, and the gap 
between clamp nuts and box must be sealed by winding with sealing tape, and meanwhile 
sealant (such as 609) or rubber dough must be applied between cable and clamp nuts.   
5. After disassembly and reassembly of parts on some other locations, such as opening 
window or on-site button etc, for some reason, users shall make sure that there will be no 
adverse effect on the sealing result.
