safety requirements.
IEC/EN 61800-3: 2004 Adjustable speed electrical power drive systems-Part
3: EMC product standard including specific test methods.
1.7 Safe instructions
Please check the model in the nameplate of the inverter and the rated value of
the inverter. Please do not use the damaged inverter in transit.
Installation and application environment should be free of rain, drips, steam,
dust and oily dirt; without corrosive or flammable gases or liquids, metal
particles or metal powder. Environment temperature within the scope of -10℃～
+50℃.
Please install inverter away from combustibles.
Do not drop anything into the inverter.
The reliability of inverters relies heavily on the temperature. The around
temperature increases by 10℃, inverter life will be halved. Because of the wrong
installation or fixing, the temperature of inverter will increase and inverter will
be damaged.
If inverter is installed in a control cabinet, smooth ventilation should be ensured
and inverter should be installed vertically. If there are several inverters in one
cabinet, in order to ensure ventilation, please install inverters side by side. If it is
necessary to install several inverters up and down, please add heat-insulation
plate.

1.8 Precautions
1.8.1 Instructions for use
Never touch the internal elements within 15 minutes after power off. Wait till it
is completely discharged.
Input terminals R, S and T are connected to power supply of 400V while output
terminals U, V and W are connected to motor.
Proper grounding should be ensured with grounding resistance not exceeding
4Ω; separate grounding is required for motor and inverter. Grounding with
series connection is forbidden.
Load switch is forbidden at output while inverter is in operation.
AC reactor or/and DC reactor is recommended when your inverter is above 37KW.
There should be separate wiring between control loop and power loop to avoid
any possible interference.
Signal line should not be too long to avoid any increase with common mode
interference.
It shall comply with the requirements for surrounding environment as stipulated
in Table 1-1 “Technical Specifications for TT100 Series Inverter”.
1.8.2 Special Warning!!
Never touch high-voltage terminals inside the inverter to avoid any electric shock.
Before inverter is powered on, please be sure that input voltage is correct.
Please do not connect input power supplyonto U,V,Wor terminals.
Please do not install inverter directly under sunshine, do not block up the cooling hole.

TT100
·6·
All safety covers should be well fixed before inverter is power connected, to
avoid any electric shock.
Only professional personnel are allowed for any maintenance, checking or
replacement of parts.
No live-line work is allowed.
1.9 Maintenance
1.9.1 Periodic Checking
Cooling fan and wind channel should be cleaned regularly to check whether it is
normal; remove the dust accumulated in the inverter on a regular basis.
Check inverter‟s input and output wiring and wiring terminals regularly and
check if wirings are ageing.
Check whether screws on each terminals are fastened.
Check whether inverter is corrosive.
1.9.2 Replacement of wearing parts
The wearing parts include cooling fan and electrolytic capacitors.
The life of the fan usually is 2~3 years. Users should change the cooling fan
according to all running time of inverter. Cooling fan could be damaged
because bearing is damaged and fan blades are aging. Users could check fan
blades for cracks or check the abnormal vibration noise when starting. Users
could change fan according to abnormal phenomena.
The useful life of electrolytic capacitors is 4~5 years. Users should change the
electrolytic capacitors according to all running time of inverter. Capacitors
could be damaged because the power supply is unstable, the environment
temperature is high, frequent over-load occurs and electrolyte is ageing. By
checking whether there is leakage of liquid, or the safety valve bulges out, or
the static electricity and insulated resistor is ok, users could change the
capacitor according to these phenomena.
1.9.3 Storage
Please put the inverter in the packing case of manufacture.
If inverter is stored for long time, please charge the inverter within half a year
to prevent the electrolytic capacitors damaged. The charging time should be
longer than 5 hours.
1.9.4 Daily Maintenance
Environment temperature, humidity, dust and vibration would decrease the life of
inverter. So daily maintenance is necessary to inverter.
Daily inspecting:
Inspecting for noise of motor when it is working.
Inspecting for abnormal vibration of motor when it is working.
Inspecting for the installing environment of inverter.
Inspecting for the fan and inverter temperature.
Daily cleaning:
Keep the inverter clean. Clean surface dust of inverter to prevent dust, metal
powder, oily dirt and water from dropping into the inverter.Inspecting for the fan
and inverter temperature.

Wiring for digital input terminals:
Generally, shield cable is adopted and wiring distance should be as short as possible. When active
signal is adopted, it is necessary to take filter measures to prevent power supply interference. Mode of
contact control is recommended.
Digital input terminals are only connected by source electrode (NPN mode) or by drain electrode (PNP
mode). If NPN mode is adopted, please turn the toggle switch to the end of “NPN”.
Wiring for control terminals as follows:
1. Wiring for positive source electrode (NPN mode).
2. Wiring for active source electrode (NPN
mode)

IV. Operation and Simple Running

TT100
·18·
This chapter defines and interprets the terms and nouns describing the control, running and status of the
inverter. Please read it carefully. It will be helpful to your correct operation.
4.1 Control mode
Control mode of TT100 inverter is V/F control.
4.2 Mode of torque compensation
Linear compensation (F137=0); Square compensation (F137=1); User-defined multipoint compensation
(F137=2); Auto torque compensation (F137=3)
4.3 Mode of frequency setting
Please refer to F203~F207 for the method for setting the running frequency of the TT100 inverter.
4.4 Mode of controlling for running command
The channel for inverter to receive control commands (including start, stop and jogging, etc) contains three
modes: 1. Keypad (keypad panel) control; 2. External terminal control; 3. Modbus control.
The modes of control command can be selected through the function codes F200 and F201.
4.5 Operating status of inverter
When the inverter is powered on, it may have four kinds of operating status: stopped status, programming
status, running status, and fault alarm status. They are described in the following:
4.5.1 Stopped status
If re-energize the inverter (if “self-startup after being powered on”is not set) or decelerate the inverter to
stop, the inverter is at the stopping status until receiving control command. At this moment, the running
status indicator on the keypad goes off, and the display shows the display status before power down.
4.5.2 Programming status
Through keypad panel, the inverter can be switched to the status that can read or change the function
code parameters. Such a status is the programming status.
There are numbers of function parameters in the inverter. By changing these parameters, the user can
realize different control modes.
4.5.3 Running status
The inverter at the stopped status or fault-free status will enter running status after having received
operation command.
The running indicator on keypad panel lights up under normal running status.
4.5.4 Fault alarm status
The status under which the inverter has a fault and the fault code is displayed.
Fault codes mainly include: OC, OE, OL1, OL2, OH, LU, PF1, representing “over current”, “over
voltage”, “inverter overload”, “motor overload”, “overheat”, “input undervoltage”, “input out-phase”, and
respectively.
For trouble shooting, please refer to Appendix I to this manual, “Trouble Shooting”.
4.6 Keypad panel and operation method
Keypad panel (keypad) is a standard part for configuration of TT100 inverter. Through keypad panel, the
user may carry out parameter setting, status monitoring and operation control over the inverter. Both keypad
panel and display screen are arranged on the keypad controller, which mainly consists of three sections: data
display section, status indicating section, and keypad operating section. There are two types of keypad
controller (with potentiometer or without potentiometer) for inverter. For details, please refer to Chapter II of
this manual, “Keypad panel”.
It is necessary to know the functions and how to use the keypad panel. Please read this manual carefully
