Safety Information
Read and follow all safety instructions in this manual precisely to avoid unsafe operating
conditions, property damage, personal injury, or death.
Safety symbols in this manual
Indicates an imminently hazardous situation which, if not avoided, will result in severe injury or
death.
Indicates a potentially hazardous situation which, if not avoided, could result in injury or death.
Indicates a potentially hazardous situation that, if not avoided, could result in minor injury or
property damage.
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 power 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
