  • Page 7: Usage/Storage Location

    1.1 Usage/Storage Location Do not use or store the product in locations such as the following. There is the risk of fire due to factors such as product failure, damage, and deterioration if this instruction is not followed.  Hot, cold, or humid locations that are not in compliance with the operating environments specified by the instruction manual.

  • Page 8: Wiring

    1.3 Wiring  Use wires whose dielectric strength corresponds to the circuit voltage. There is the risk of electric shock if you use wires without dielectric strength.  Fully cover the input and output terminals and the conducting parts of the wires with tubes, tape, or other such insulating objects.

  • Page 9: Precautions During Usage

    PRECAUTIONS DURING USAGE Pay attention to the following when using the unit.  The main circuit thyristor may be damaged in short circuit mode. To prevent fire and property damage in case of ground faults, ensure that the design is safe by, for example, installing protective functions on the power input side of the unit main circuit using breakers or other devices.
  • Page 10  A load must be connected during test operation. When test operation is performed with no load, voltage continues to be applied to the output terminal. Additionally, do not perform test operation with no load while the external potential transformer (PT) is connected. Doing so may damage the unit.
