1.4.1 Delivery and installation





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.
R, S and T are the power input terminals, and U, V and W are output motor terminals.

Connect the input power cables and motor cables properly; otherwise, damage to the
inverter may occur.
Only trained and qualified electricians are allowed to carry out related
operations.
Do not perform wiring, inspection, or component replacement when power
supply is applied. Ensure all the input power supplies are disconnected before
wiring and inspection and wait for at least the time designated on the inverter
or until the DC bus voltage is less than 36V. The minimum waiting time is listed
in the table below.
Inverter model
380V HD2IP-9.5A-43
Do not refit the inverter unless authorized; otherwise, fire, electric shock or
other injuries 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 prevent electrostatic discharge during related operation.
Install the inverter on fire-retardant material and keep the inverter away from
combustible materials.
Connect the optional brake parts (brake resistors, brake units or feedback
units) according to the wiring diagram.
Do not operate on a damaged or incomplete inverter.
Do not touch the inverter with wet items or body parts; otherwise, electric
shock may occur.
