Special Cautions
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:
Case of control box
Case of connection box
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.
