3-8-3 Absorption of Regenerative Energy with the External
Regeneration Resistor (Models Conforming to UL/cUL
Standards and Models Not Conforming to Any
Standards)
Connect one or more external regeneration resistors when a Regeneration Unit (R88A-
RG08UA) cannot absorb all of the regenerative energy. Remove the short bar from be-
tween the RG and JP terminals on the Regeneration Unit and connect the resistor be-
tween the P and RG terminals. Connecting to the wrong terminals may destroy the Re-
generation Unit, so connect the resistor carefully. (The Regeneration Unit does not con-
form to EC Directives.)
The external regeneration resistor will heat to approximately 120
_
C. Do not install it near
devices or wiring that is sensitive to heat. Install heat radiation plates suitable to the radi-
ation conditions.
