Chapter 2 Installation and Wiring
2.1 External Dimension and Installation Dimension (See Appendix
1)
2.2 Mounting Place Requirements and Management
·Don’t carry the inverter by its cover. The cover cannot support the weight of the inverter and may drop.
·Please install the inverter on a strong support, failing which the inverter may fall off.
·Don’t install the inverter in places where water pipes may leak onto it.
·Don’t allow screws, washers and other metal foreign matters to fall inside the inverter, otherwise there is a
danger of fire or damage.
·Don’t operate the inverter if parts are not complete, otherwise there is a danger of fire or human injury.
·Don’t install the inverter under direct sunshine; otherwise, it may be damaged.
·Don’t short circuit PB, + and -, otherwise there is a danger of fire or the inverter may be damaged.
·Cable lugs must be connected to main terminals firmly.
·Don’t apply supply voltage (AC 220V) to control terminals except terminals TA, TB, TC.
Please mount the inverter as following application occasions and maintain appropriate condition
2.2.1 Installation Location
The installation location should meet the following conditions:
Good indoor ventilation
Ambient temperature: -10 °C ~ 40 °C. If the temperature is higher than 40 °C, the inverter should be forced
ventilation is required and derating used.
Humidity should be lower than 95%, no condensing and rain water drops.
Do not mount the inverter on the timber or other combustible matters.
Avoid direct sunlight.
It is strictly prohibited to install the inverters in places where have flammable, explosive, corrosive gases or
liquids;
Mount in the location free of dust, metal powder, corrosive gas or combustible gas.
The installation foundation should be solid and free of vibration.
No electromagnetic interference, away from source of interference.
Attention

Chapter 2 Installation and Wiring
9
Derating use must be considered when the inverter is installed at high altitude, greater than 1000 m. This is
because the cooling effect of inverter is deteriorated because of the thin air. Derating 6% per 1000 m higher of
the altitude.
2.2.2 Ambient Temperature
In order to enhance operating reliability of the inverter, be sure where the inverter mounted has a good ventilation;
when the inverter is used in a closed case, cooling fans or an air-conditioning must be installed to keep the ambient
temperature below 40℃
2.2.3 Preventive Measures
Installing the inverter, please set a shield to prevent metal debris falling into it, and remove the shield after installing.
Please remove the protection membrane when the ambient temperature is over 40° C or the internal temperature is
too high due to other reasons. Please pay attention to avoid small parts falling into the inverter.
2.3 Installation Direction and Space
Inverters of this series are all equipped fans for forced cooling. In order to be an effective cooling cycle, the inverter
must be mounted in the vertical direction, up, down, left and right away from adjacent articles or baffle (wall)
maintain adequate space, as Figure 2-1

2.4.2 Main Circuit Wiring operation
When the motor is running, please make sure if it is in positive rotation while the motor receives positive rotation
command. If the motor is in reverse rotation, the rotation direction of the motor can be changed by exchanging any
two wires of output terminals (U, V, and W) of the inverter. The rotation direction can also be changed by modifying
the function code P2.37 to change the phase sequence of the motor.
Do not mistakenly connect the input power cable to the output terminal; otherwise the components in the inverter
will be damaged. Output terminals are prohibited to be grounded. The lines should not be collided with the
enclosure, or short connected; otherwise the inverter will be damaged.
Earth terminal PE must be grounded. 380V class grounding resistance should be 10Ω or less. The earth wire should
never share with electric welder or power equipment. The earth wire should be of conductor diameter specified in the
technical standard for electrical equipment, and should be as close to the ground point as possible. On occasions
using more than two inverters at the same time, please do not form the earth wire into ring circuit. Proper grounding
method and incorrect grounding method are shown in Fig. 2-9.

Figure 2-9 Earthing Connection Method
Notes: The neutral point of motor using Y connection can’t be connected to earth.
Since the inverter output PWM wave, if a capacitor for improving power factor or a lightning varistor is installed on
the output side, which would case tripping or damage to parts, be sure to remove it.
If a contactor or other on-off part is needed to be installed between the output and the motor, be sure the on-off
operation is done when the inverter has no output, otherwise the inverter would be damaged.
Countermeasures to conduction interference: To inhibit conduction interference of the output, besides installing
noise filter and using shielded motor cables, leading all the output cables to earthing metal tube is also a method.
Make the distance between the output cables and the control signal cables greater than 30 cm, the effect of
conduction interference will obviously decrease too.
Countermeasures to RFI: The input cables, output cables and the inverter itself would produce RFI. Placing noise
filters both at input and output sides, and shielded with metal shell would reduce RFI. The cables between the
inverter and the motor should be as short as possible. Measure to reduce RFI is shown as Figure 2-10.

The longer the distance between the inverter and the motor, the higher the carrier frequency would be, and the
greater the high harmonic leakage current of the cables would be. Leakage current has a negative impact to inverters
and Equipment nearby, so reduce leakage current as little as possible.
The relationship of the distance between the inverter and the motor and carrier frequency is shown as Table 2-7

In order to reduce interference and attenuation of control signal, the length of control cables should be limited
in 50m and away from power cables for more than 30cm. Avoid control wire and power wire being parallel. Try to
use STP (Shielded Twisted Pair) to connect analog input and output signal.

2.5.2 Wiring of control circuit terminals
●Wiring of analog input terminals
AI1/AI2 terminals accept analog signal input, toggle switches SW1 and SW3 select the input voltage (0 ~ 10V) or
the input current (0 ~ 20mA). AI3 (exclusive for 35R5GB and above models) terminals accept analog signal input,
toggle switch SW4 selects the input voltage ( - 10 ~ 10V) or the input current (-20 ~ 20mA). The wiring of terminals
is shown in Fig. 2-14:

●Wiring of analog output terminal
In S2R4GB ~ 3004GB, analog output terminal AO1 external connecting analog meter can indicate a variety of
physical quantities. Slide switch SW2 selects the output voltage (0/2 ~ 10V) or the output current (0/4 ~ 20mA). The
wiring of terminals is shown in Fig. 2-15:
