adapters from other manufacturers, even if these units
have a registered approval rating from a national
testing laboratory, requires the approval of an
authorized Sartorius service technician.

The IP 65 protection rating is ensured only if the square
rubber gasket is installed and the plug
is connected securely to form a leak-tight seal.
