CHV180 series frequency inverter special for elevator Wiring
.12.
4. Wiring
Only qualified electricians are allowed to operate on the drive for the insurance
of a safe running of the inverter.
Never carry out any insulation or voltage withstand tests on the cables
connecting with the inverter.
Even if the servo drive is stopped, dangerous voltage is present at the input
power lines, DC circuit terminals and motor terminals. Wait for 10 minutes even
when the inverter is switched off until is discharge before operation.
Ground the grounding terminals of the inverter with proper techniques. The
grounding resistor will be less than
10Ω.
Otherwise there is danger of electrical
shock and fire.
Do not connect the 3 phase power supply to the output terminals of the inverter
(U, V, and W), otherwise damage may occur to the inverter.
Please ensure right connection between the power wires and the motor wires.
The power wire is connected with the terminals of R, S and T. And the motor
wire is connected with the terminals of U, V and W.
Never do wiring or other operations on the inverter with wet hands. Otherwise
there is danger of electric shock
Verify that the rated voltage of the servo drive equals to the voltage of the AC
power supply.
The power wires and motor wires must be permanently fastened and
connected.
