Safety Guidelines - Salicru CV30 User Manual

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:
1PH 220V
3PH 220V
3PH 380V
 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 resistors 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 installer 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.
