result in severe personal injury or serious damage to material. Only suitably qualified
personnel trained in the setup, installation, commissioning and operation of the product
should carry out work on the device/system.
Only permanently-wired input power connections are allowed.

4
1.2 DuringPower Up
Danger
When the momentary power loss is longer than 2 seconds, the inverter will not have
sufficient stored power for its control circuit. Therefore, when the power is re-applied,
the run operation of the inverter will be based on the setup of following parameters:
Run parameters. 00-02 or 00-03.
Direct run on power up. Parameter. 07-04 and the status of external run switch,
Note-: The start operation will be regardless of the settings for parameters
07-00/07-01/07-02.
Danger. Direct run on power up.
If direct run on power up is enabled and inverter is set to external run
with the run FWD/REV switch closed then the inverter will restart.
Danger
Prior to use, ensure that all risks and safety implications are considered.
When the momentary power loss ride through is selected and the power loss is short,
the inverter will have sufficient stored power for its control circuits to function, therefore,
when the power is resumed the inverter will automatically
restart depending on the setup of parameters 07-00 & 07-01.
1.3 Before Operation
Caution
Make sure the model and inverter capacity are the same as that set in parameter 13-00.
Note: On power up the supply voltage set in parameter 01-01 will flash on display
for 2 seconds.
1.4 During Operation
Danger
Do not connect or disconnect the motor during operation. Otherwise, It may cause the
inverter to trip or damage the unit.
Danger
To avoid electric shock, do not take the front cover off while power is on.
The motor will restart automatically after stop when auto-restart function is enabled. In
this case, care must be taken while working around the drive and associated equipment.
The operation of the stop switch is different than that of the emergency stop switch. The
stop switch has to be activated to be effective. Emergency stop has to be de-activated to
become effective.

5
Caution
Do not touch heat radiating components such as heat sinks and brake resistors.
The inverter can drive the motor from low speed to high speed. Verify the allowable
speed ranges of the motor and the associated machinery.
Note the settings related to the braking unit.
Risk of electric shock. The DC link capacitors remain charged for five minutes after
power has been removed. It is not permissible to open the equipment until 5 minutes
after the power has been removed.
Caution
The Inverter should be used in environments with temperature range from (14-104℉)
or (-10 to 40℃) and relative humidity of 95%.
Note: models with fan: -10~50℃, models without fan: -10~40℃
Danger
Make sure that the power is switched off before disassembling or checking any
components.

3.1.1 Wiring and EMC guidelines
For effective interference suppression, do not route power and control cables in the same conduit or
trunking.
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.
BL51 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.

Conductor size for enclosure &
Back plate must comply with the local electrical
standards. minimum 10mm².
2. Back plate. Galvanized steel (unpainted).
3. Ferrite core / Output reactor.
Ferrite cores can be used to reduce
radiated noise due to long motor cables.
If ferrite core is used loop motor wires, 3times
round the core. Install core as close to the
inverter as possible
Output reactors provide additional
benefit of reducing dv/dt for protection of motor
windings.
4. Metal Cable clamp no more than 150mm from
the inverter.
Note: If no enclosure & back plate is used then
connect the cable shield by a good 360 º
termination to the Inverter output terminal E.
5. Screened (Shielded four core cable).
6. Separate Protective Earth wire, routed outside
motor cable separated by at least 100mm.
Note: - this is the preferred method
especially for large output cables and long
length.
Multi-core screened (3 core & protective
earth) can be used for small power and short
length.
7. Connect the cable shield by a good
360º termination and connect to themotor

3.1.2 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
BL51 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 :
( 400V : L1,L2,L3).
Warning! Connecting the 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%.

Notes:
1. It is required to reconnect after setting Master and Slave.
2. It is required to short the COM and AGND port of frame3 and frame 4 when pressure
converter connected with +24Vpower supply.
3. When the communication modes is selected to be multiple pumps in parallel connection, the
baud rate setting 09-02 of Master and Slave are required to be consistent. Refer to parameter
14-31 for the actions in parallel connection modes.
