SD1 Series Inverters Safety Precautions
-2-
1.3 Safety Guide
Only qualified electricians are allowed to operate on the inverter.
Do not perform any wiring, inspection, or component changes when the
power supply is connected. Ensure the power supply is disconnected
before wiring or any inspection takes place, and always wait for at least
the appropriate designated time, or until the DC bus voltage is less than
36V. See table below for waiting times:
Do not carry out any unauthorized refitting of the inverter; otherwise, fire,
electric shock or other serious injury may occur.
The base of the heatsink may become hot during running. Do not touch to
avoid harm.
The electrical parts and components inside the inverter are electrostatic.
Take precautions to avoid electrostatic discharge during related 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 optional brake parts (braking resistors, braking units, or
feedback units) according to the wiring diagram.
Do not work on or operate the inverter if there is any damage to the
inverter, or any component loss.
Do not touch the inverter with wet items; otherwise, electric shock may
Note:
Select appropriate tools for moving and installing the inverter to ensure a safe and normal
installation, avoiding physical injury or death. For physical safety, the installer should take
the necessary precautions, such as wearing protective 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 public places.
The leakage current of the inverter may be above 3.5mA during operation. Ground properly
and ensure the grounding resistor is less than 10Ω. The conductivity of PE grounding
conductor is the same as that of the phase conductor.
R, S and T are the input terminals of the power supply, while U, V and W are the motor
