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
