Connect the shield to inverter

ground terminal

Do not connect this end

3-8

3.3.3 Wiring and EMC guidelines.

For effective interference suppression, do not route power and control cables in the same

conduit or trucking.

To prevent radiated noise, motor cable should be put in a metal conduit. Alternatively an

armored or shielded type motor cable should be used.
For effective suppression of noise emissions the cable armor or shield must be grounded at
both ends to the motor and the inverter ground. These connections should be as short as
possible.
Motor cable and signal lines of other control equipment should be at the least 30 cm apart.

L510 has a built in Class “A” EMC filter to first Environment Restricted. (Category C2).
For some installations such as residential,(Category C1) an optional external Class “B” type
filter will be necessary. Please consult your local supplier.

3.3.4 Failure liability

¾ Teco bears no responsibility for any failures or damaged caused to the inverter if the

recommendations in this instruction manual have not been followed specifically
points listed below,

¾ If a correctly rated Fuse or Circuit breaker has not been installed between the power

source and the inverter.

¾ If a magnetic contactor, a phase capacitor, burst absorber and LC or RC circuits have

been connected between the inverter and the motor.

¾ If an incorrectly rated three-phase squirrel cage induction motor has been used

Note:

When one inverter is driving several motors, the total current of all motors running
simultaneously must be less than the rated current of the inverter, and each motor
has to be equipped with a correctly rated thermal overload relay.

3-10

3.3.5 Considerations for peripheral equipment

(

Power

Ensure that the supply voltage is correct.
A molded-case circuit breaker or fused disconnect
must be installed between the AC source and the
inverter

Circuit
Breaker

& RCD

Use a molded-case circuit breaker that conforms to
the rated voltage and current of the inverter.
Do not use the circuit breaker as the run/stop switch
for the inverter.
Residual Current Circuit Breaker(RCD)
Current setting should be 200mA or above and the
operating time at 0.1 second or longer to prevent
malfunctions.

Magnetic
contactor

Normally a magnetic contactor is not needed.
A contactor can be used to perform functions such
as external control and auto restart after power
failure.
Do not use the magnetic contactor as the run/stop
switch for the inverter.

AC reactor for
power quality
improvement

When a 200V/400V inverter with rating below 15KW
is connected to a high capacity power source
(600KVA or above) then an AC reactor can be
connected for power factor improvement and
reducing harmonics.

Input noise
filter

L510 inverter has a built-in filter to Class “A” first
Environment. (CategoryC2)
To satisfy the required EMC regulations for your
specific application you may require an additional
EMC filter.

Inverter

Connect the single phase power to Terminals, L1(L)

& L3(N) and three phase power to Terminals :
(200V : L1(L),L2,L3(N) or 400V : L1,L2,L3)

Warning! Connecting the input terminals T1, T2,
and T3 to AC input power will damage the inverter.
Output terminals T1, T2, and T3 are connected to U,
V, and W terminals of the motor.
To reverse the motor rotation direction just swap
any two wires at terminals T1, T2, and T3.
Ground the Inverter and motor correctly.
Ground Resistance for 200V power<100 Ohms.

Motor

Three-phase induction motor. Voltage drop on
motor due to long cable can be calculated.
Volts drop should be < 10%.
Phase-to-phase voltage drop (V) =

3 ×resistance of wire (Ω/km)×length of line

(m)×current×10

3.3.6 Ground connection

Inverter Ground terminal must be connected to installation ground correctly and
according to the required local wiring regulations.

¾ Ground cable size must be according to the required local wiring

regulations. Ground connection should be as short as possible.

¾ Do not share the ground of the inverter with other high current loads (Welding

machine, high power motors). Ground each unit separately.

¾ Ensure that all ground terminals and connections are secure

¾ Do not make ground loops when several inverters share a common ground point.

3.8 EMC Filter Disconnection

EMC filter may be disconnected:
Inverter drives with built-in EMC filter are not suitable for connection to certain type of
supply systems, such as listed below; in these cases the RFI filter can be disabled.

In all such cases consult your local electrical standards requirements.
IT type supply systems (ungrounded) & certain supply systems for medical

equipment.

For ungrounded supply systems If the filter is not disconnected the supply system
becomes connected to Earth through the Y capacitors on the filter circuit. This could

result in danger and damage to the Drive.

Disconnection steps:

1. Remove EMC filter protection cover by screwdriver.

2. Remove EMC line by pliers.
Note:- Disconnecting the EMC filter link will disable the filter function, please consult your local
EMC standards requirement..

Is the load too excessive? Reduce the load.

Does the load vary excessively?

1.Minimize the variation of the load.

2.Consider increasing the capacities of the
inverter and the motor.

Consider adding an AC reactor at the power
input side if using single-phase power.

Motor speed
varies
unusually

Is the input power unstable or is
there a phase loss ?

2. Check wiring if using three-phase power

Is the power connected to the
correct L1, L2, and L3 terminals?
is the charging indicator lit ?

1 Is the power applied?

2.Turn the power OFF and then ON again.

3.Make sure the power voltage is correct.

4.Make sure screws are secured firmly.

Is there voltage across the output
terminals T1, T2, and T3?

Turn the power OFF and then ON again.

Is overload causing the motor to
stall?

Reduce the load so the motor will run.

Are there any abnormalities in the
inverter?

Is there a forward or reverse run
command ?

See error descriptions to check wiring and
correct if necessary.

Has the analog frequency signal
been input?

1.Is analog frequency input signal wiring correct?

2.Is voltage of frequency input correct?

Motor can
not run

Is the operation mode setting
correct?
