Disposal and recycling instructions
The R250 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).
