CT100 inverter Safety precautions

1 Safety precautions
Please read this manual carefully and follow all safety precautions before
installing, debugging, maintaining and repairing the inverter.
If any physical injury or death or damage to the devices occurs for ignoring to the
safety precautions in the manual, our company will not be responsible for any
damages and we are not legally bound in any manner.
Following the warning symbols are used in this manual:
Serious physical injury or even death may occur if not follow the relative
requirements.
Physical injury or damage to the devices may occur if not follow the
relative requirements.
1.1 Safety guidelines
1.1.1 Before installation
» Do not operate the inverter if there are any signs of water in the inverter when
unpacking.
» Do not operate the inverter if there is any damage or components loss to the
inverter when unpacking. Otherwise, physical injury or damage to the devices
may occur.
» Do not touch the control terminals, PCB board or components inside the
inverter with hands or body.
» Do not operate the inverter if the packing list is not consistent with the devices.
» Do not operate the inverter if the information on the type designation label is
not consistent with your order.
1.1.2 Installation

CT100 inverter Safety precautions
2
» Only qualified electricians are allowed to perform the installation, otherwise
electric shock may occur.
» Please install the inverter on fire-retardant materials and keep the inverter
away from combustible materials, otherwise a fire may occur.
» Please assemble and tighten the mounting screws of the inverter according
to the regulations, otherwise the inverter may fall off.
» Do not install the inverter in explosive atmospheres, otherwise an explosion
may occur.
» Handle the inverter with care to prevent it falls off and thus causes injury to
your feet or device damage.
» Keep the inverter away from the places with large vibrations, water drops
and direct sunlight.
» When installing the inverter in the cabinet, especially if two or more inverters
are installed in a cabinet, please pay attention to the installation space and
ventilation.
» Take measures to avoid screws, cables and other conductive matters fall
into the inverter during installation.
1.1.3 Wiring
» Only qualified electricians are allowed to perform the wiring, otherwise
electric shock or device damage may occur.
» Carry out wiring strictly in accordance with this manual, otherwise there is a
risk of electric shock or device damage.
» Ensure all input power supply is disconnected before wiring, otherwise
electric shock may occur.
» Please select all cables, circuit breakers and contactors meeting the national
standards as required by the manual.
» The inverter must be grounded reliably, otherwise electric shock may occur.
» Carry out wiring strictly in accordance with the silk printing instructions and
avoid connecting the input and output wires reversely, otherwise the damage
to the devices may occur.

CT100 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.
1.1.4 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.

1.2 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
exceeds, derate 1% for every additional 100m.

external braking resistors and you need to purchase the resistors by yourselves.
2. The inverters of power between CT100-4T-18G/22P-B～
CT100-4T-37G/45P-B are built-in with DC reactors. The inverters of power
between CT100-4T-45G/55P～CT100-4T-315G/355P are mounted with external
DC reactors and you need to purchase the reactors by yourselves. The inverters
of power between CT100-4T-355G～CT100-4T-500G are applied with input AC
reactors.
3. The above models are the standard general inverters, excluding the industrial
special inverters. You can customize non-standard inverters of other
specifications.
