Other preparations
1.
Check that there is no damage, deformation, or other defects on the cabinet.
2.
Open the controller cabinet door and check for problems such as loose wires or switches in the wrong position.
3.
Check that the terminal boards on the main control box are in the right positions.
4.
Check that the optical fiber connections are in good condition.
5.
Open the transformer cabinet and check that the connections of the wiring terminals are in good condition.
6.
Make sure that there is no contact between the high and low-voltage circuits.
7.
Check that the temperature sensor installation is in good condition.
8.
Open the power cell cabinet and check that the connections in the front of the power cell are solid.
9.
Check that the installation of the voltage and current sensors is correct and that the jacks of the signal wires are firmly
connected.
10.
Check that the grounding copper busbars are connected reliably.
11.
Make sure that there is no condensation on the surfaces of the AC drive.
12.
Make sure that there are no unwanted objects in the installation space.
13.
Check that the input power of the drive meets the drive specification.
14.
Check that the output voltage of the drive matches the rated voltage of the motor.
15.
Check that the control power supply matches the drive specification.
16.
Check that the rated power of the drive matches the motor specification.
17.
Check that the secondary transformer wiring is correct according to the secondary wiring diagram.
18.
Check that the primary wiring is correct according to the primary wiring diagram.
19.
Make sure that the motor cable shield is grounded at the drive and motor ends of the cable.
20.
Make sure that the control cables are as far as possible from the power cables.
21.
Make sure that the cables do not touch the electrical components of the drive.
22.
Do a check of the tightening torques of all the terminals.
23.
Make sure that the AC drive and the motor are grounded.
24.
Make sure that the shields of the shielded cables are connected to a grounding terminal that is identified with the ground-
ing symbol.
25.
Check that the resistances of the grounding copper busbars match the requirements.
•
Control system grounding: ≤0.5 Ω
•
System safety grounding: ≤0.5 Ω
•
Machine cabinet support: ≤0.5 Ω
•
Transformer support: ≤0.5 Ω
•
External housing of the cooling fans: ≤0.5 Ω
•
Door locks: ≤0.5 Ω
26.
Check that all cables meet the requirements.
See
6.7 Power Cable
27.
Do an insulation test for the control power.
a.
Disconnect the control power input.
b.
Measure the insulation resistance of the 220 V AC terminal at the outgoing parts of the bypass switches QF11,
QF12, and QF13.
Use a 2500 V insulation resistance tester.
The insulation resistance must be higher than 1 MΩ.
28.
Provide an auxiliary AC supply.
29.
Make sure that the installation follows EMC guidelines.
