Power supply voltage must meet the requirements, do not over voltage or under-voltage use.
When installing or repairing the gate, please cut off the input power first.
Please make sure that door opener is grounded reliably, the grounding resistance is less than 4 Ω, and there are leakage and short circuit protection.
The the proper position of the door opening machine on the track, a limit iron should be firmly welded, which should be outside the range of the electric appliance limit, so that it is appropriate to block the two sides of the walking wheel an the door body does not leave the guide wheel constraints. To prevent the electrical limit failure gate from both side of the guide wheel constraints caused by over turning.
Before the door is opened, obstacles should be cleared; vehicle and pedestrians are strictly prohibited from passing through the gate while it is in operation.
