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
of 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
E510s has a built-in filter (Class A/First Environment
Category C2, except for Frame 4)
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).
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 have to less than 100 Ohms.
Ground Resistance for 400V have to less than 10 Ohms
Motor
Three-phase induction motor.
Voltage drop on motor due to long cable can be
calculated, volts drop should be less than 10%.
The formula of Phase-to-phase voltage drop is
(V) = 3 ×resistance of wire (Ω/km)×length of
line(m)×current×10
