Wiring External Regeneration Resistors
Remove the short bar from between the RG and JP terminals on the Regeneration Unit and connect the
resistor(s) between the P and RG terminals.

Note The thermal switch output must be connected in the same way as the ALM output from the Re-
generation Unit, i.e., so that power supply is broken when the contacts open. If a power interrup-
tion sequence based on the output is not included in the circuit, the Regeneration Unit may be
damaged.
