Installation steps
Pretreatment of the installation location
Cleaning the surface: Clean the wall or panel surface where the button is installed, remove dust, debris and oil, etc., to ensure that the surface is flat and smooth.
Check the flatness and firmness: Check whether the wall or panel at the installation location is flat. If there is unevenness or instability, it needs to be repaired or reinforced to ensure that the button will not shake or tilt after installation.
Install the button body
Place the button: Place the button at the predetermined installation location so that the button is flush with the wall or panel. Pay attention to the correct direction and position of the button.
Determine the drilling position and size: According to the design requirements of the button, use tools such as rulers or templates to determine the location and size of the drilling hole, and mark it.
Drilling: Use an electric drill to drill according to the marked position. When drilling, pay attention to keeping the drill bit perpendicular to the wall or panel to avoid tilting the drilling.
Insert and tighten the button: Align the fixing hole of the button with the drilling hole, gently insert the button, and then use tools such as screwdrivers or wrenches to tighten the fixing nut to firmly fix the button on the wall.
Check stability: After installation, shake the button gently to check whether it is firmly installed and whether it is loose. If it is loose, it needs to be re-tightened.
Connect wires
Cut off the power supply: Before connecting the wires, the power supply of the elevator system must be cut off to ensure safe operation. A warning sign can be set at the power switch to prevent others from closing the switch by mistake.
Connect the button wires to the system interface: Connect the button wires to the corresponding interfaces of the elevator system. Usually, the button wires will have different color markings, such as red for live wires and black for neutral wires. Connect them correctly according to the corresponding relationship.
Fix the wires: Use insulating tape or terminal blocks to fix the wires to ensure a firm connection to prevent the wires from loosening or falling off. At the same time, pay attention to avoid squeezing or abrasion of the wires.
Check the connection: After the connection is completed, check again whether the wires are firmly connected, whether there are any missing or wrong connections, and use tools such as multimeters to test whether the circuit is conductive.
