CT100G Series Inverter Safety precautions
- 3 -
»Keep the signal cables of the inverter away from the power cables as far as
possible, or distribute the two categories of cables vertically-crossed if the
distance is not far enough, otherwise it may cause signal interference.
» Ensure that all the screws are tightened when wiring, otherwise damage to
the inverter may occur.
» The encoders and sensors should be applied with the shielded cables and
the shielded layer should be grounded reliably.
Operation
» Confirm that the wiring is completed and correct and then cover the plate
before power on.
» Do not open the plate after power on, otherwise electric shock may occur.
» Operate the inverter appropriately, otherwise damage to the inverter may
occur.
» Non-professionals are not allowed to test the signals when the inverter is
running. Otherwise, physical injury or damage to the devices may occur.
» Do not change the parameters of the inverter at random, otherwise damage
to the inverter may occur.
» Do not touch the fans and brake resistors, otherwise it may cause
mechanical injury or burn.
» Do not start up or stop the inverter by power on or off, otherwise damage to
the inverter may occur.
» Ensure that the circuit breakers or contactors at the output sides of the
inverter are not in output state before switching, otherwise damage to the
inverter may occur.

Others
» This inverter is not suitable for the occasions when the specifications exceed
those specified in this manual. If you have special requirements, please
contact our technical department.
» The inverter is equipped with surge suppressors inside, which can protect it
from the lightning. It is necessary to mount external surge suppressors at the
power input side of the inverter in high lightning incidence areas.
» When the conductors between the inverter and the motor exceed 100m, it is
recommended to mount the output reactors to avoid overcurrent caused by
excessive distributed capacitance.
» Do not mount the compensation capacitors and the surge absorbers at the
output sides of the inverter. Otherwise, it may cause damage to the inverter
due to overheating.
» Mounting the input or output reactors, special filters and magnetic rings at
the input or output sides of the inverter can effectively reduce the noise and
thus avoid interference to other devices.
» Non-professionals are not allowed to perform withstand voltage tests on the
inverter, , otherwise damage to the inverter may occur.
» Deal with the devices as industrial effluent after scrapping. Burning is strictly
prohibited, otherwise an explosion may occur.
» The cooling effect of the inverter is reduced and the electrolytic capacitor
electrolyte is also volatile in high altitude areas, which will shorten the life of
the inverter. Check the altitude of the actual usage site is below 1000m. If
higher than 1000m, reduce 1% for every additional 100m.

Note: 1. The inverters with power less than or equal to CT100G-4T-160G are
equipped with braking units, but 37-160kw models are optional with or without
braking units. And braking resistors inside whose power and resistance are as
required as the table 2-2, otherwise has risk of damage. CT100G-4T-185G and
bigger power models can be equipped with external braking units bought by
customers themselves.
2. The above models are the standard general purpose inverters, excluding the
industrial special inverters. You can customize non-standard inverters of other
specifications.

CHAPTER 2 INSTALLATION AND WIRING
2.1 Installation environment
1. Ambient temperature: -10℃～+40℃, derate to use if the temperature is above
40℃
2. Relative humidity: ≤ 95%, no condensation
3. Vibration: ＜0.5g
4. The inverter should be installed on the flame-retardant materials and there is
enough space for heat dissipation.
5. The inverter can output the rated power when the altitude is below 1000m. If
the altitude is above 1000m, the output power will decrease. It is recommended
to derate 1% for every additional 100m.
6. The inverter is not allowed to fall to the ground suddenly.
7. The inverter is not allowed to be installed near the electromagnetic radiation
sources.
8. The inverter is not allowed to be installed in the atmospheres with flammable,
explosive or corrosive gases.
9. The inverter is not allowed to be installed in the environments with direct
sunlight, oil mist or steam.
10. Avoid screws, cables, drilling debris and other conductive matters falling into
the inverter during installation, otherwise it may cause the inverter failure.
11. For the bad installation environments (like textile industry), it is recommended
to install the radiator outside the cabinet.

Circuit breaker
Cut off the power and protect the latter when the latter devices
have failure.
Select the circuit breaker of the breaking current by 2 times of
the inverter.
Leakage

PWM high frequency chopper voltage output causes high
frequency leakage current, so select a special leakage
protector.
Contactor
Frequent switching on-off the contactor causes inverter failure,
so do not start or stop the inverter by switching on-off the main
circuit, which will affect the life of the inverter.
Input reactor

Improve the input power factor;
Reduce the impact on the system caused by the unbalance of

it to the PE terminal of the inverter. Keep the control cable away from the main
circuit and strong power circuit (including power cables, motor cables, relays,
contactors, etc.) more than 20cm. Vertical wiring is recommended instead of
parallel wiring to prevent the inverter malfunction caused by external

By using the internal +24V power supply of the inverter, the wiring of the external
controller for the PN type source current is as shown below:
Figure 2-8 Wiring of PNP type source current
Note: Be sure to remove the short-circuit plate between +24V and PW and
connect the plate between PW and COM.
