SAFETY INSTRUCTIONS
Always follow safety instructions to prevent accidents and potential hazards
from occurring.
In this manual, safety messages are classified as follows:
WARNING
Improper operation may result in serious personal injury or
death.
CAUTION
Improper operation may result in slight to medium personal
injury or property damage.
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.
WARNING
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.

    What causes inverter overload in LSIS DC Drives?
    • S
      Samuel JohnsonAug 21, 2025
      The LSIS DC Drive will turn off its output when the output current exceeds the rated level (150% for 1 minute), indicating an inverter overload.
  • K
    Kyle PhillipsAug 25, 2025
    Why does LSIS DC Drives show an over voltage error?
    • N
      Nicholas SmithAug 25, 2025
      The LSIS DC Drive turns off its output if the DC voltage of the main circuit rises above 400V during motor deceleration, which is often caused by a surge voltage in the power supply system.

    What causes heat sink overheat in LSIS DC Drives?
    • G
      Gary BishopAug 26, 2025
      The LSIS DC Drive will turn off its output if the heat sink overheats. This can be caused by a damaged cooling fan or foreign objects obstructing the cooling fan.
  • B
    Brandon WilliamsAug 28, 2025
    Why does LSIS DC Drives show a low voltage error?
    • D
      Dana WhiteAug 28, 2025
      The LSIS DC Drive turns off its output if the DC voltage drops below 180V. This is because insufficient torque or overheating of the motor can occur when the input voltage of the inverter drops.

    What causes output phase loss in LSIS DC Drives?
    • C
      Christopher RuizAug 30, 2025
      The LSIS DC Drive turns off its output if one or more of the output phases (U, V, W) are open.

    What causes instant cut off in LSIS DC Drives?
    • J
      Jared BergSep 5, 2025
      The inverter instantly turns off the output when the EST terminal is turned on in LSIS DC Drives.
  • R

    What does external fault A contact input mean on LSIS DC Drives?
    • C
      Carl HensonSep 7, 2025
      When the multi-function input terminal (I20-I24) is set to 19 {External fault signal input : A (Normal Open Contact)}, the LSIS DC Drive turns off the output.
