Disposal and recycling instructions
WARNING
The AVR R221 is dedicated for the alternators LSA40 and LSA423 single phase
(50Hz/60Hz). It is particularly recommended for applications in which the alternator’s
voltage difference between no-load operation and load operation is out of ISO8528-3
class G2.
The R221 is an IP00 product. It must be installed inside a unit so that this unit’s cover can
provide IP20 minimum total protection (it must only be installed on our alternators in the
appropriate location so that when viewed externally, it has a higher degree of protection than
IP20).
