SAFETY INSTRUCTIONS
1. Electrical Shock Prevention
• Do not open the front cover of the inverter while power is on
or while the inverter is running, as an electrical shock may
result.
• Do not operate the inverter with the front cover or wiring cover
removed, as accidental contact with exposed high-voltage
terminals and internal components may occur, resulting in an
electrical shock.
• If power is off, do not remove the front cover except when
necessary for wiring or periodic inspection. While the front
cover is removed, accidental contact with exposed high-
voltage terminals and internal components may occur,
resulting in an electrical shock.
• Prior to starting wiring or inspection, confirm that input power
to the inverter has been switched off via observation of the
inverter’s display panel. Additionally, wait for at least 10
minutes after removal of input power, and then confirm that all
residual voltage has been dissipated by using a voltage meter.
Internal DC bus capacitors may contain high voltages for
several minutes after removal of input power, resulting in a
dangerous situation should anything come into contact with
them.
• All personnel involved in the installation or inspection of this
equipment should be fully competent to perform the required
work.
• Always install plug-in options prior to wiring main power.
• Do not touch the plug-in option with wet hands.
• Do not subject the cables to scratches, excessive stress,
