Installation hole dimensions for embedded installation
Note 1: The ventilation area is approx. 100 × 120.
Note 2: Attach packing to the flange section.
Note 3: Do not wire or arrange other devices in front of the section marked with a * as extremely hot wind will be blown out.
Note 4: For the installation direction of this resistor, the "Ceiling" is the top and "Ground" is the bottom.
Note 5: Touching the resistor when it is hot could lead to burns. Always install a protective cover or consider the installation site so
that workers will not touch the unit.
Note 6: The resistor's heating value will differ according to the acceleration/deceleration frequency, speed being used and the load
2
GD conditions, etc. However, install the resistor so that the hot wind is always exhausted to outside the panel.
