8.2 Check before Power on
After installation of electrical control systems, electrical parts must be checked:
1. Check the connection of all parts, according to the user manual and electrical schematic
diagram.
2. Check whether the strong current part and the weak current part are connected. Check the
resistance between various voltage circuits with ohm grade of a multimeter, and the grounding
resistance should be ∞.
3. Please carefully check whether the power incoming line of the control cabinet and motor
connections are correct, to avoid burning the elevator integrated drive controller after power on.
4. Check whether the control cabinet case, motor case, car grounding wire, hall door grounding
wire are reliably and securely connected, to ensure personal safety.
▲ Note: The cabinet case and the motor case should be one point grounding.
