Do not operate on a damaged or incomplete inverter.
Do not touch the inverter with wet items or body parts; otherwise, electric
shockmay occur.
Note:
Select appropriate tools for delivery and installation to ensure a safe and proper running of
the inverter and avoid physical injury or death. To ensure physical safety, the installation
staff should take mechanical protective measures like wearing safety shoes and working
uniforms.
Ensure to avoid physical shock or vibration during delivery and installation;
Do not carry the inverter by its front cover only as the cover may fall off;
Installation site should be away from children and other public places;
The inverter should be used in proper environment (see section 4.2.1 "Installation
environment" for details);
Prevent the screws, cables and other conductive parts from falling into the inverter;
As leakage current of the inverter during running may exceed 3.5mA, ground properly and
ensure the grounding resistance is less than 10Ω. The conductivity of PE grounding
conductor is the same with that of the phase conductor. For models higher than 30 kW, the
cross sectional area of the PE grounding conductor can be slightly less than the
recommended area.

1.4.2 Commissioning and running
Disconnect all power sources applied to the inverter before terminal wiring and
wait for at least the time designated on the inverter after disconnecting the
power sources.
High voltage is present inside the inverter during running. Do not carry out any
operation on the inverter during running except for keypad setup. It must be
noted that the control terminal of inverter is ELV (Extra Low Voltage)
circuit,
which cannot be connected directly to the accessible terminals of other
devices if no protective isolation measure is taken. For instance, RS485
terminal of the inverter can be connected to RS232 interface of the PC only
after a converter with protective isolation is connected between them.
The inverter
may start up by itself when P01.21 (restart after power down) is
set to 1. Do not get close to the inverter and motor.
The inverter cannot be used as "Emergency-stop device".
The inverter cannot act as an emergency brake for the motor; it is a must to
install mechanical brake device.
During driving permanent magnet synchronous motor, besides above-
mentioned items, the following work must be done before installation and
maintenance.
1. Disconnect all the input power sources including main power and control
power.
2. Ensure the permanent-magnet synchronous motor has been stopped, and
the voltage on output end of the inverter is lower than 36V.
3. After the permanent-magnet synchronous motor is stopped, wait for at
least
the time designated on the inverter, and ensure the voltage between "+"
and "-" is lower than 36V.
4. During operation, it is a must to ensure the permanent-magnet
synchronous motor cannot run again by the action of external load; it is
recommended to install effective external brake device or disconnect the
direct electrical connection between permanent-magnet synchronous
motor and the inverter.
Note:
Do not switch on or switch off input power sources of the inverter frequently.
For inverters that have been stored for a long time, set the capacitance and carry out
inspection and pilot run on the inverter before use.
Close the front cover before running; otherwise, electric shock may occur.
1.4.3 Maintenance and component replacement

After the inverter is installed properly, check the installation condition of the inverter.
1. Check whether the input power cable and current-carrying capacity of the motor cable
fulfill actual load requirements.
2. Check whether peripheral accessories (including input reactors, input filters, output reactors,
output filters, DC reactors, brake units and brake resistors) of the inverter are of correct type
and installed properly; check whether the installation cables fulfill requirements on
current-carrying capacity.
3. Check whether the inverter is installed on fire-retardant materials, check whether the
hot parts (reactors, brake resistors, etc.) are kept away from combustible materials.
4. Check whether all the control cables are routed separately with power cables based on
EMC requirement.
5. Check whether all the grounding systems are grounded properly according to
inverter requirements.
6. Check whether installation spacing of the inverter complies with the requirements
in operation manual.
7. Check whether installation mode of the inverter complies with the requirements
in operation manual. Vertical installation should be adopted whenever possible.
8. Check whether external connecting terminals of the inverter are firm and tight enough,
and whether the moment is up to the requirement.
9. Check whether there are redundant screws, cables or other conductive objects inside
the inverter, if yes, take them out.
2.6 Basic commissioning
Carry out basic commissioning according to the following procedures before operating on the
inverter.
1. Select motor type, set motor parameters and select inverter control mode according
to actual motor parameters.
2. Whether autotuning is needed? If possible, disconnect the motor load to carry out
dynamic parameter autotuning; if the load cannot be disconnected, perform static autotuning.
3. Adjust the acceleration and deceleration time based on actual working conditions of the
load.
4. Jogging to carry out device commissioning. Check whether the motor running direction
is consistent with the direction required, if no, it is recommended to change the motor running
direction by exchanging the motor wiring of any two phases.
5. Set all the control parameters and carry out actual operation.

3 Product Overview
3.1 What this chapter contains
This chapter mainly introduces the operation principles, product features, layouts, nameplates,
and model instructions.
3.2 Basic principle
The HD2 IP55 high-ingress protection series inverter is used to control asynchronous AC
induction motor and permanent-magnet synchronous motor. The figure below shows the
main circuit diagram of the inverter. The rectifier converts 3PH AC voltage into DC voltage,
and the capacitor bank of intermediate circuit stabilizes the DC voltage. The inverter converts
DC voltage into the AC voltage used by AC motor. When the circuit voltage exceeds the
maximum limit value, external brake resistor will be connected to intermediate circuit to
consume the feedback energy.
