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.
