2.2 Installation
2.2.1 Installation environment
1) Environment temperature: the operating environment temperature has a great influence on the
service life of the variable frequency drive. The operating environment temperature of the variable
frequency drive is not allowed to exceed the allowable temperature range (-10°C ~+50 °C).
2) The variable frequency drive is installed on the surface of the flame-retardant object, leaving
enough heat dissipation space around. When the variable frequency drive works, it is easy to
generate a large amount of heat. And it is vertically installed on the installation support base by
screws.
3) The variable frequency drive is installed in a place that is not easy to vibrate. If it is installed in a
vibrating place, it must ensure that the vibration is not more than 0.6g. Pay special attention to
keep away from punching machines and other equipment.
4) The variable frequency drive shall be avoided being installed in places with direct sunlight,
humidity and condensed water drops.
5) It is avoided being installed in corrosive, flammable and explosive air.
6) It is avoided being installed in occasions with oil stains and dust.
2.2.2 Installation space and direction
TI120 series variable frequency drives have different reserved sizes of surrounding installation
space and spacing space according to different variable frequency drive power levels.
When installing the variable frequency drive, it shall be installed in a vertical and upward direction. It
is forbidden to install it by lying down, lying on one's side, upside down and other installation methods
that do not meet the installation requirements.

2.3.4 Wiring note of main circuit
1) Input power supply R,S,T
● There is no phase sequence requirement for the input side wiring of the variable frequency
drive.
● The specifications and installation methods of external power wiring shall conform to the
requirements of local regulations and relevant IEC standards.
● For power cable wiring, please select copper wires with corresponding sizes according to the
values in the recommendation table in chapter 2.3.3.
2) DC bus+,-
● Pay attention to the residual voltage at the terminals (+), (-) of the DC bus just after the power
failure, and wait for the indicator lamp to turn off, and confirm that the power failure will last for 10
minutes before wiring operation, otherwise there is a risk of electric shock.
● When selecting external brake components for 160kW and above, pay attention to that the
polarity of (+), (-) cannot be reversed, otherwise the variable frequency drive will be damaged
or even fire disaster.
● Wiring length of brake unit shall not exceed 10m. Twisted pair or tight two-wire parallel wiring
shall be used.
● Do not connect the brake resistor directly to the DC bus, and it may cause damage to the
variable frequency drive or even fire disaster.
3) Brake resistor terminals B1, B2/+
● For models with 132kW or below and confirmed to have built-in brake unit, the brake resistor
wiring terminal is valid.
● The brake resistor selection shall be selected according to the recommended value and the
wiring distance shall be less than 5m. Otherwise, the variable frequency drive may be
damaged.
4) variable frequency drive outputs U, V, W
● The specifications and installation methods of external power wiring shall conform to the
requirements of local regulations and relevant IEC standards.
● For power cable wiring, please select copper wires with corresponding sizes according to the
values in the recommendation table in 2.3.3.
● Capacitors or surge absorbers shall not be connected to the output side of the variable
frequency drive; otherwise the variable frequency drive will be frequently protected or even
damaged.
● When the motor cable is too long, it is easy to generate electrical resonance due to the influence
of distributed capacitance, so it shall cause insulation damage of the motor or larger leakage
current to make the variable frequency drive over-current protection. When the length of the

TI120 Series Variable Frequency Drive System Installation and Wiring

motor cable is more than 100m, an AC output reactor must be installed near the variable
frequency drive.
5) Grounding terminal
● Terminals must be reliably grounded and the resistance of grounding wire must be less than
10Ω. Otherwise, the equipment will work abnormally or even be damaged.
● Do not share the grounding terminal with the N terminal of the neutral line of the power
supply.
● The impedance of the protective grounding conductor must meet the requirement of
withstanding short-circuit large current in case of failure.
● The size of the protective grounding conductor shall be selected according to the following
table.
