2.4 Peripheral Electrical Devices and System Configuration
When the SSI700 is used to control the synchronous or asynchronous motor, forming a
control system, it is necessary to install various electrical devices on the input and output
sides of the AC drive to ensure the system safety and stability.
Figure 2-2 System configuration of three-phase 220 V/380 V voltage class, 2.2 Kw and
above

Part Mounting Location Function Description
MCCB Power receiving side Interrupt the power supply when overcurrent occurs on
down stream devices
Contactor Between MCCB and
AC drive input side
Start and stop the AC drive.
Do not start and stop the AC drive frequently by switching
the contactor on and off (less than twice per minute) nor use
it to directly start the AC drive.
AC input
reactor AC drive input side
• Improve the power factor of the input side.
• Eliminate the higher harmonics of the input side effectively
and prevent other devices from being damaged due to
distortion of the voltage waveform.
• Eliminate the input current unbalance due to unbalance
between the power phases.

Part Mounting Location Function Description
EMC
Input filter AC drive input side
• Reduce the external conduction and radiation interference
of the AC drive.
• Decrease the conduction interference flowing from the
power end to the AC drive and improve the anti interference
capacity of the AC drive.
AC output
reactor
Between AC drive output
side and the motor, close
to the AC drive
The output side of the AC drive generally has much higher
harmonics. When the motor is far from the AC drive, there is
much distributed capacitance in the circuit and certain
harmonics may cause resonance in the circuit, bringing
about the following two impacts:
• Degrade the motor insulation performance and damage
the motor in the long run.
• Generate large leakage current and cause frequent AC
drive protection trips.
If the distance between the AC drive and the motor is
greater than 50 m, install an AC output reactor.
1) Do not install the capacitor or surge suppressor on the output side of the AC drive.
Otherwise, it may cause faults to the AC drive or damage to the capacitor and surge
suppressor.
2) Inputs/Outputs (main circuit) of the AC drive contain harmonics, which may interfere
with the communication device connected to the AC drive. Therefore, install an anti-
interference filter to minimize the interference.
3) For more details on peripheral devices, refer to related selection manual.

The optional parts include braking unit of different functions and external operation panel,
etc. If any optional part is required, specify it in your order.

Chapter 3 Mechanical and Electrical Installation
3.1 Mechanical Installation
3.1.1 Installation Environment Requirements
Item Requirements
Ambient temperature -10°C to +50°C
Heat dissipation
Install the AC drive on the surface of an incombustible object, and
ensure that there is sufficient space around for heat dissipation.
Install the AC drive vertically on the support using screws.
Mounting location
Free from direct sunlight, high humidity and condensation
Free from corrosive, explosive and combustible gas
Free from oil dirt, dust and metal powder
Vibration Less than 0.6 g
Far away from the punching machine or the like
Protective enclosure
The SSI700 series AC drives of plastic housing are the whole unit
built-in products operated through remote control and need to be
installed in the final system.The final system must have the required
fireproof cover, electrical protective cover and mechanical protective
cover, and satisfy the regional laws & regulations and related IEC
requirements.
3.1.2 Installation Clearance Requirements
The clearance that needs to be reserved varies with the power class of the SSI700, as
shown in the following figure.
Figure 3-1 Clearance around the SSI700 for installation
The SSI700 series AC drive dissipates heat from the bottom to the top. When multiple AC
drives are required to work together, install them side by side.
For application installing multiple AC drives, if one row of AC drives need to be installed
above another row, install an insulation guide plate to prevent AC drives in the lower row
from heating those in the upper row and causing faults.

SSI700 User Manual Mechanical and Electrical Installation
www.ssinverter.info

■ Installation Precautions
1) Reserve the installation clearances as specified in Figure 3-1 to ensure sufficient space
for heat dissipation. Take heat dissipation of other parts in the cabinet into consideration.
2) Install the AC drives upright to facilitate heat dissipation. If multiple AC drives are
installed in the cabinet, install them side by side. If one row of AC drives need to be
installed above another row, install an insulation guide plate .
3) Use incombustible hanging bracket.

(other voltage classes).
U, V, W AC drive output terminals Connect to a three-phase motor.
Grounding terminal Must be grounded.
3.2.2 Wiring of AC Drive Main Circuit
■ Precautions on the Wiring
1) Power input terminals R, S, T
– The cable connection on the input side of the AC drive has no phase sequence
requirement.
– The specification and installation method of external power cables must comply with the
local safety regulations and related IEC standards.
– Use copper conductors of a proper size as power cables according to the recommended
values in section 8.3.
2) Braking resistor connecting terminals B1 , B2
– The connecting terminals of the braking resistor are effective only for the AC configured
with the built-in braking unit.
– The cable length of the braking resistor shall be less than 5 m. Otherwise, it may
damage the AC drive.
3) AC drive output terminals U, V, W
– The specification and installation method of external power cables must comply with the
local safety regulations and related IEC standards.
– Use copper conductors of a proper size as power cables according to the recommended
values in section 8.3.
– The capacitor or surge absorber cannot be connected to the output side of the AC drive.
Otherwise, it may cause frequent AC drive fault or even damage the AC drive.
– If the motor cable is too long, electrical resonance will be generated due to the impact of
distributed capacitance. This will damage the motor insulation or generate higher leakage
current, causing the AC drive to trip in overcurrent protection. If the motor cable is greater
than 100 m long, an AC output reactor must be installed close to the AC drive.
4) Terminal PE
– This terminal must be reliably connected to the main earthing conductor. Otherwise, it
may cause electric shock, mal-function or even damage to the AC drive.
– Do not connect the earthing terminal to the neutral conductor of the power supply.
– The impedance of the PE conductor must be able to withstand the large shortcircuit
current that may arise when a fault occurs.
– Select the size of the PE conductor according to the following table:
Cross-sectional Area of a
Phase Conductor (S)
Min. Cross-sectional Area of
Protective Conductor (Sp)
S ≤16 mm2S
16 mm2 < S ≤35 mm216 mm2
35 mm2 < S S/2

SSI700 User Manual Mechanical and Electrical Installation
www.ssinverter.info

– You must use a yellow/green cable as the PE conductor.
5) Requirements on upstream protection device
– Install upstream protection device on the input power circuit. The protection device must
provide the protections on overcurrent, short-circuit and electrical solation.
– When selecting the protective device, you should consider the current capacity of the
power cable, system overload capacity and short-circuit capacity of the upstream power
distribution of the equipment. Generally, make selection according to the recommended
values in section 8.4.

■ Description of Wiring of Signal Terminals
1) Wiring of AI terminals
Weak analog voltage signals are easy to suffer external interference, and therefore the
shielded cable must be used and the cable length must be less than 20 m, as shown in
following figure.
Figure 3-4 Wiring mode of AI terminals
In applications where the analog signal suffers severe interference, install filter capacitor
or ferrite magnetic core at the analog signal source.
Figure 3-5 Install filter capacitor or ferrite magnetic core
2) Wiring of DO terminal
When the digital output terminal needs to drive the relay, an absorption diode shall be
installed between two sides of the relay coil. Otherwise, it may cause damage to the
24 VDC power supply. The driving capacity is not more than 50 mA.
Note
Do not reverse the polarity of the absorption diode during installation, as shown in Figure 3-3.
Otherwise, the 24 VDC power supply will be damaged immediately once there is digital output.
