OPERATING AND MAINTENANCE MANUAL
PYD SERIES SOLAR INVERTER
26
•
Ground the frequency inverter correctly as standard. Failure to do so may result in electric
shock.
•
Never connect the power supply wires to the output terminals (U, V, W) of the inverter.
Failure to comply will result in damage to the inverter.
•
Ensure that all connection cables comply with EMC requirements and the safety standard
of the region. Use the cable sizes recommended in the manual. Failure to comply may
result in accidents.
•
Never connect the braking resistor between the DC bus terminals (P +) and (P-). Failure to
comply may result in fire.
•
Never connect the power supply wires to the output terminals (U, V, W) of the inverter.
Failure to comply will result in damage to the inverter.
•
Ensure that all connection cables comply with EMC requirements and the safety standard
of the region. Use the cable sizes recommended in the manual. Failure to comply may
result in accidents.
•
Never connect the braking resistor between the DC bus terminals (P +) and (P-). Failure to
comply may result in fire.
Before ignition:
•
Check that the following requirements are met:
•
The voltage class of the power supply is consistent with the rated voltage class of the fre-
quency converter. The input terminals (R, S, T) and output terminals (U, V, W) are connec-
ted correctly. There is no short circuit in the peripheral circuit. The wiring is secure. Failure
to comply will result in damage to the frequency converter.
•
Cover the frequency converter properly before switching it on to avoid electric shock.
•
Do not perform the voltage withstand test on any part of the frequency inverter because
the voltage withstand test has been performed at the factory. Failure to do so will result in
accidents.
•
All peripheral devices must be connected correctly according to the instructions described
in this manual. Failure to do so will result in accidents.
