improve the reliability. Goodrive300-16 inverters have safe and reliable fault protection
function, built-in realtime clock, two groups of PID adjusters and multi-motor combined
system and available BACnet communication, etc.
With EMC design, Goodrive300-16 inverters can meet the demand of environmental
protection which focuses on low noise and weakening electromagnetic interference in the
application sites for the customers.
This manual provides installation and configuration, parameters setting, fault diagnoses and
daily maintenance and relative precautions to customers. Please read this manual carefully
before the installation to ensure a proper installation and operation and high performance of
Goodrive300-16 inverters.
If the product is ultimately used for military affairs or manufacture of weapon, it will be listed
on the export control formulated by Foreign Trade Law of the People's Republic of China.
Rigorous review and necessary export formalities are needed when exported.

Chapter 1 Safety precautions
1.1 What this chapter contains
Please read this manual carefully and follow all safety precautions before moving, installing,
operating and servicing the inverter. If ignored, physical injury or death may occur, or
damage may occur to the devices.
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.
1.2 Safety definition
Danger:
Serious physical injury or even death may occur if not follow
relevant requirements
Warning:
Physical injury or damage to the devices may occur if not follow
relevant requirements
Note:
Physical hurt may occur if not follow relevant requirements
Qualified
electricians:
People working on the device should take part in professional
electrical and safety training, receive the certification and be
familiar with all steps and requirements of installing,
commissioning, operating and maintaining the device to avoid any
emergency.
1.3 Warning symbols
Warnings caution you about conditions which can result in serious injury or death and/or
damage to the equipment, and advice on how to avoid the danger. Following warning

1.4 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
380V
4kW-110kW
5 minutes
380V
132 kW
15 minutes
Do not refit the inverter unauthorizedly; 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
measures to avoid electrostatic discharge during relevant operation.
1.4.1 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.

Goodrive300-16 special inverter for HVAC Safety precautions

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 measures, 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.
Please use the inverter on appropriate condition (See chapter Installation
Environment).
Do not allow screws, cables and other conductive items to fall inside the inverter.
The leakage current of the inverter may be above 3.5mA during operation. High
leakage current, earth connection essential before connecting supply. 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 Tare 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.
1.4.2 Commission 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.

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.
1.4.3 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.
Carry out a sound anti-electrostatic protection to the inverter and its internal
components during maintenance and component replacement.

Hibernation starting
deviation
5.0%
Relative to the maximum PID1 value
Allow hibernation only when the output
feature is positive, feedback is larger than
reference, the absolute value of the actual
deviation is larger than the value and the
hold time is larger than P22.04.
Allow hibernation only when the output
feature is negative, feedback is smaller
than reference, the absolute value of the
actual deviation is larger than the value
and the hold time is larger than P22.04.

the feedback cannot reach the set value
after boost, the inverter will enter
hibernation immediately after boost time.
