Important Safety Instructions
Operation Warnings
• Your inverter produces a modified sine wave, not a pure sine
wave. Inductive loads like a refrigerator or drill are not suitable for
long-term use with a modified sine wave inverter. Otherwise, it may
damage or shorten the working life of the inverter or associated
devices.
• Your inverter does not require routine maintenance. Do not open the
device for any reason. There are no user-serviceable parts inside.
• Potentially lethal voltages exist within the inverter as long as the
battery is connected. During any service work, the battery should
therefore be disconnected.
• Do not connect or disconnect batteries while the inverter is
operating. Dangerous arcing may result.
