● R-UNIT-1, R-UNIT-2
2-ø6 hole
Ceiling
Ground
Embedded installation
(outer heat radiating section)
Note 1: Do not wire or arrange other devices in front of the section marked with a * as extremely hot wind will be blown out.
Note 2: For the installation direction of this resistor, the "Ceiling" is the top and "Ground" is the bottom.
Note 3: 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 4: The resistor's heating value will differ according to the acceleration/deceleration frequency, speed being used and the load
