Ensure power is disconnected before installation.
Use M3.5 stainless steel screws with flat washers/spring washers for fixation, torque: 0.69~0.98N·m.
Avoid dropping the switch from a height exceeding 30cm to prevent ceramic housing damage.
The actuator and stopper should be vertically aligned.
Avoid excessively slow or fast operating speeds; ensure it is within the rated range.
Over-travel (OT) should be set within 70%~100% of the rated value.
Do not use in corrosive environments containing silicon gas, hydrogen sulfide, ammonia, etc.
Non-waterproof structure; install a protective cover in occasions with oil/water splashing.
Prevent chips and dust from accumulating on the actuator and body.
Avoid long-term exposure to hot water or steam environments above 60℃.
