Thank you for purchasing LS Variable Frequency Drives!
Always follow safety instructions to prevent accidents and potential hazards from occurring.
In this manual, safety messages are classified as follows:
WARNING
CAUTION
Throughout this manual we use the following two illustrations to make you aware of safety considerations:
Identifies potential hazards under certain conditions.
Read the message and follow the instructions carefully.
Identifies shock hazards under certain conditions.
Particular attention should be directed because dangerous voltage may be present.
Keep operating instructions handy for quick reference.
Read this manual carefully to maximize the performance of SV-iC5 series inverter and ensure its safe use.
Do not remove the cover while power is applied or the unit is in operation.
Otherwise, electric shock could occur.
Do not run the inverter with the front cover removed.
Otherwise, you may get an electric shock due to high voltage terminals or charged capacitor
exposure.
Do not remove the cover except for periodic inspections or wiring, even if
the input power is not applied.
Otherwise, you may access the charged circuits and get an electric shock.
Wiring and periodic inspections should be performed at least 10 minutes
after disconnecting the input power and after checking the DC link voltage
is discharged with a meter (below DC 30V).
Otherwise, you may get an electric shock.
Operate the switches with dry hands.
Otherwise, you may get an electric shock.
Do not use the cable when its insulating tube is damaged.
Otherwise, you may get an electric shock.
Do not subject the cables to scratches, excessive stress, heavy loads or
pinching.
Otherwise, you may get an electric shock.
