Safety Information

Safety information
•Do not open the cover of the equipment while it is on or operating. Likewise,
do not operate the inverter while the cover is open. Exposure of high voltage
terminals or charging area to the external environment may result in an
electric shock. Do not remove any covers or touch the internal circuit boards
(PCBs) or electrical contacts on the product when the power is on or during
operation. Doing so may result in serious injury, death, or serious property
damage.
•Do not open the cover of the equipment even when the power supply to the
inverter has been turned off unless it is necessary for maintenance or regular
inspection. Opening the cover may result in an electric shock even when the
power supply is off.
•The equipment may hold charge long after the po
wer supply has been turned
off. Use a multi-
meter to make sure that there is no voltage before working on
the inverter, motor or motor cable.
•Supply earthing system: TT, TN, not suitable for corner-earthed systems.
•Wait at least 10 minutes before opening t
he covers and exposing the terminal
connections. Before starting work on the inverter, test the connections to
ensure all DC voltage has been fully discharged. Personal injury or death by
electric shock may result.
•Do not install this equipment on or near combustible material. Doing so may
cause a fire.
•This equipment must be electrically grounded for safe and proper operation.
•Do not use or supply power to a faulty inverter. If the inverter is faulty,
disconnect the power supply and arrange for qualified technical support.
•
The inverter will become hot during normal operation. To avoid burns, do not

Safety Information
touch the inverter until it has cooled.
•Do not allow foreign objects, such as screws, metal filings, debris, water, or
oil to enter the inverter. Foreign objects inside the inverter may cause the
inverter to malfunction or result in a fire.
•Do not touch the inverter with wet hands. Doing so may result in electric
shock.
•Do not modify the inverter. Doing so will void the warranty.
•The inverter is designed to operate 3-phase motors. Do not use the inverter
to operate single phase motors.
•Do not place heavy objects on top of electric cables. Doing so may damage
the cable and result in electric shock.
