1.3 Safety guidelines
Only qualified electricians are allowed to operate on the inverter.
Do not carry out any wiring and inspection or changing components
when the power supply is applied. Ensure all input power supply is
disconnected before wiring and checking and always wait for at least
the time designated on the inverter or until the DC bus voltage is less

than 36V. Below is the table of the waiting time:
Inverter module
Minimum waiting time
1PH 230V
0.4kW-2.2kW
5 minutes
3PH 400V
0.75kW-110kW
5 minutes
Do not refit the inverter unauthorized; otherwise fire, electric shock or
other injury may occur.
The base of the radiator may become hot during running. Do not
touch to avoid hurt.
The electrical parts and components inside the inverter are
electrostatic. Take measurements to avoid electrostatic discharge
during relevant operation.
1.3.1 Delivery and installation
Please install the inverter on fire-retardant material and keep the
inverter away from combustible materials.
Connect the braking optional parts (braking resistors, braking units or
feedback units) according to the wiring diagram.
Do not operate on the inverter if there is any damage or components
loss to the inverter.
Do not touch the inverter with wet items or body, otherwise electric
shock may occur.
Note:
Select appropriate moving and installing tools to ensure a safe and normal running of the
inverter and avoid physical injury or death. For physical safety, the erector should take some
mechanical protective measurements, such as wearing exposure shoes and working
uniforms.
Ensure to avoid physical shock or vibration during delivery and installation.
Do not carry the inverter by its cover. The cover may fall off.
Install away from children and other public places.
The inverter cannot meet the requirements of low voltage protection in IEC61800-5-1 if the
sea level of installation site is above 2000m.
The leakage current of the inverter may be above 3.5mA during operation. Ground with
proper techniques and ensure the grounding resistor is less than 10Ω. The conductivity of PE
grounding conductor is the same as that of the phase conductor (with the same cross
sectional area).
R, S and T are the input terminals of the power supply, while U, V and W are the motor
terminals. Please connect the input power cables and motor cables with proper techniques;
otherwise the damage to the inverter may occur.
1.3.2 Commissioning and running
Disconnect all power supplies applied to the inverter before the
terminal wiring and wait for at least the designated time after
disconnecting the power supply.
High voltage is present inside the inverter during running. Do not carry
out any operation except for the keypad setting.
The inverter may start up by itself when P01.21=1. Do not get close to
the inverter and motor.
The inverter can not be used as “Emergency-stop device”.
The inverter can not be used to break the motor suddenly. A
mechanical braking device should be provided.

DRV-24 frequency inverters Safety precautions

Note:
Do not switch on or off the input power supply of the inverter frequently.
For inverters that have been stored for a long time, check and fix the capacitance and try to
run it again before utilization (see Maintenance and Hardware Fault Diagnose).
Cover the front board before running, otherwise electric shock may occur.
1.3.3 Maintenance and replacement of components
Only qualified electricians are allowed to perform the maintenance,
inspection, and components replacement of the inverter.
Disconnect all power supplies to the inverter before the terminal
wiring. Wait for at least the time designated on the inverter after
disconnection.
Take measures to avoid screws, cables and other conductive matters
to fall into the inverter during maintenance and component
replacement.
Note:
Please select proper torque to tighten screws.
Keep the inverter, parts and components away from combustible materials during
maintenance and component replacement.
Do not carry out any isolation and pressure test on the inverter and do not measure the
control circuit of the inverter by megameter.
1.3.4 What to do after scrapping
There are heavy metals in the inverter. Deal with it as industrial
effluent.
2 Product Overview
2.1 Quick start-up
2.1.1 Unpacking inspection
Check as follows after receiving products:
1. Check that there are no damage and humidification to the package. If not, please

3 Installation Guidelines
The chapter describes the mechanical installation and electric installation.
Only qualified electricians are allowed to carry out what described in
this chapter. Please operate as the instructions in Safety Precautions.
Ignoring these may cause physical injury or death or damage to the
devices.
Ensure the power supply of the inverter is disconnected during the
operation. Wait for at least the time designated after the
disconnection if the power supply is applied.
The installation and design of the inverter should be complied with the
requirement of the local laws and regulations in the installation site. If
the installation infringes the requirement, our company will exempt
from any responsibility. Additionally, if users do not comply with the
suggestion, some damage beyond the assured maintenance range
may occur.
3.1 Mechanical installation
3.1.1 Installation environment
The installation environment is the safeguard for a full performance and long-term stable functions
of the inverter. Check the installation environment as follows:

temperature
-10°C~+50°C, and the temperature changing rate is less than
0.5°C/minute.
If the ambient temperature of the inverter is above 40°C,
derate 1% for every additional 1°C.
It is not recommended to use the inverter if the ambient
temperature is above 50°C.
In order to improve the reliability of the device, do not use
the inverter if the ambient temperature changes frequently.
Please provide cooling fan or air conditioner to control the
internal ambient temperature below the required one if the
inverter is used in a close space such as in the control
cabinet.
When the temperature is too low, if the inverter needs to
restart to run after a long stop, it is necessary to provide an
external heating device to increase the internal temperature,

Route the motor cable, input power cable and control cables separately.
3.2.3 Wiring of terminals in main circuit
1. Fasten the grounding conductor of the input power cable with the grounding terminal of the
inverter (PE) by 360 degree grounding technique. Connect the phase conductors to L1, L2 and L3
terminals and fasten.
2. Strip the motor cable and connect the shield to the grounding terminal of the inverter by 360
degree grounding technique. Connect the phase conductors to U, Vand Wterminals and fasten.
3. Connect the optional brake resistor with a shielded cable to the designated position by the same
procedures in the previous step.
4. Secure the cables outside the inverter mechanically.
