*1. Select a combination that has an absorption capacity greater than the average regeneration power (Pr).
*2. Do not use a combination with resistance values lower than the minimum external regeneration resistance of each drive. For
 Surface temperatures on regeneration resistance can reach 200C.
Do not place objects that tend to catch fire nearby. To prevent people from touching them, install a
cover that enables heat dissipation.
