5. If customers don't purchase limit switches, please install the limit switches at the stroke positions of the extension tube
of an actuator yourself and combine that limiter for power failure on controllers and power suppliers to ensure the
power can be disconnected when the extension tube of an actuator moves to the stroke and wire position.
6. The actuator is DC driven. When the two input wires of motor power are exchanged, the extension tube of the
actuator will reversely move. Please use proper controllers and power suppliers while stop. Two input wires of motor
power are short-circuited to provide auxiliary brake. Note that the power of actuator motor should be disconnected
and then short-circuited to avoid short circuit on power supplier.
7. Don't operate up to the stroke limit if there are no limit switches and controllers have no overload protection.
8. Don't apply actuators over the maximum load indicated by the specifications.
9. If the actuator isn't water-proof, please follow the water-proof regulations.
10. Controller power: AC100/110/120/220/230V[50/60Hz] ; the required input power is shown on the controller's
specification tag.
11. Operating temperature: +5°C ~ +40°C (+41°F ~ +104°F).
12. Type of protection of applied parts against electric shock is BF and B.
13. The temperature of Products under storage and transmission is -10℃~+50℃.
14. The clean method of product：Alcoho l（70%）.
15. The procedure of the broken product：Recycle by local rules.
16. The product should be installed in a safe place where is allowed to take off the plug easily in an emergency situation.
17. Cycle of inspection (every six months).
18. The hospital bed cleaning procedure must depend on actuator water-proof level while actuator has assembled with
hospital bed.
19. The temperature of Products under storage and transmission is -10~+50℃ and it need to be stored in no wet, no dust,
no corrosion gas or liquid environment.
20. If client need to adjust the location of external limit, please make mark on original spot (drawing line with pen、sticker
gluing etc.) to prevent linear actuator get damaged.
21. The specification of the external limit please refer to approved drawing and guidebook.
