Safety Guidelines - HBD PV500-0007M1 User Manual

PV500 series solar pumping inverters

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.
● 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 erector should
take some mechanical protective measurements, such as wearing safety shoes and
working uniforms.
● Do not carry the inverter by its cover. The cover may fall off.
● Ensure to avoid physical shock or vibration during delivery and installation.
● Install away from children and other public places.
● The inverter cannot meet the requirements of low voltage protection in IEC61800-5-1 if
the altitude 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).
