Chapter 3 Installation and Wiring

3.1 Safety Precautions

This chapter explains the warnings that must be followed to ensure that the user can safely use the product,
maximize the performance of the inverter, and ensure reliable operation of the inverter.
Cautions in use
:
● While install the inverter in the closed cabinet, please build in cooling fan, air-conditioner
or other cooling equipment to ensure the temperature at the air-in port below 40℃. So that
the inverter can work safely and reliably.
● While installing, please use cloth or paper cover the inverter to prevent metal dust, oil,
water and others.And remove it carefully after working.
● While operation, please follow the ESD regulations. Otherwise, the inverter may be
damaged.
● While multi inverters are installed in the same cabinet, enough space must be left for
cooling fan.
● Inverter cannot work over rated range. Otherwise, the inverter may be damaged.
● While transporting the inverter, please hold the firm case. If only hold the pre-cover, there
is danger of inverter main body falling, injury or inverter damage.

Cautions in use motor

● Different motor has different max allowable running speed. Motor can not run over the
max allowable running speed.
● While inverter is running at low speed, the motor auto-cool effect is seriously worse. If
motor runs at low speed for long time, it will be damaged for overheat. If needed, please use
special motor for inverter.
● While constant speed machinery runs at inconstant speed, there maybe sympathetic
vibration. Please install vibration-proof rubber under motor rack or use jumping frequency
control function.
● While using frequency inverter or working frequency power supply to drive, the torque
characteristic are different. Please do confirm the torque characteristic of the equipment
connected.
● The rated current of diving motor is higher than that of standard motor, please confirm it
and choose the right inverter.
● While the wire between motor and inverter is long, the max torque of the motor will reduce
for voltage drop. So please use thick cable while the distance between the motor and the
inverter is long.
