After finishing the wire layout, check the following things:
1. Are all the connections correct?
2. Is there any connection left out?
3. Is there any short circuit or line-to-ground short circuit between the
terminals and the connecting wires?
When the power is on, if the connections need to be changed, first
the power supply should be turned off, and the filter capacitor of the DC
part of the loop will need some time to discharge electricity. The work only
can begin after the completion of electricity discharge. Besides, because
of the residual voltage, sparks may be generated when there is a short
circuit, thus it’s better to conduct the work under voltage-free conditions.
1.Grounding wire must be connected, or electric shock or fire may
happen.
2.The wiring work should be done by the professional technicians.
3.Start the work after confirming that the power is OFF or electric
shock may happen.
Basic Wire Layout Graph
The wires of AC drive can be divided into main loop and control loop.
Users can open the upper cover and see the terminals of main loop and
control loop. Users must lay the wires according to the figure below to
ensure the accuracy of connections.
D
uring the wiring, the selection of the specification of wire diameter
should be in accordance with the standards of electrical engineering for
safety. The screws of the terminals should be tightened, preventing the
sparks caused by loose screws due to vibration. The standard wire layout
figure for EC5000 AC drive is shown below.

2.4 Instruction for Wire Layout
After removing the upper cover, the connection terminal strips are
exposed, check whether the terminals of main loops and control loops
are marked explicitly and pay attention to the following instructions
during connection, do not make improper connections.
2.4.1 Basic Wire Layout
■
The power supply must be connected with the terminals of the main
loops of AC
drive R/L1, S/L2, T/L3. If the power supply is improperly
connected with other terminals, the AC drive will be damaged. Besides,
check whether the voltage/current of the power supply is within the
allowable range indicated on the nameplate.
■
The grounding terminals must be grounded well, on the one hand it can
prevent electric shock or fire, and on the other hand it can reduce the
noise interference.
■
Connect the terminals with wires, ensure the high reliability of the
connection.
