4.2 Electrical equipment
• Operating voltage see label 50/60 Hz
• Current rating see label
• Protection Class 1, i.e. operating isolation with ground connection to EN 61 010
• Protection IP20 to DIN EN 60 529
• Interference suppression to EN55011 Class B
• Oven protected by a fuse 250V/15A fast blow
• Controller protected by a 100 mA fuse (200 mA on 115 V)
• When connecting a MEMMERT oven to the electrical supply you have to observe any local
regulations which apply (e.g. in Germany DIN VDE 0100 with FI protection circuit)
This product is intended to operate on a supply network with a system impedance Zmax at the
transfer point (building connection) of 0.292 Ohm max. The user has to ensure that the product is
only operated on an electrical supply network which meets these requirements. If necessary, details
of the system impedance can be obtained from the local electricity supply authority.
Note:
Any work involving opening up the oven must only be carried out by a suitably qualified
electrician!
4.3 External connection
Equipment connected to the external connections must have interfaces which meet the requirements for
safe low voltage (e.g. PC, printer).
4.4 Material quality from MEMMERT:
• External casing: stainless steel (Mat.Ref. 1.4016)
• Piping: stainless steel (Mat.Ref. 1.4571)
• Working space: stainless steel (Mat.Ref. 1.4404) featuring high stability, optimal hygienic properties,
and corrosion resistance against many (not all!) chemical compounds (warning against chlorine
compounds, for example).
• Thermoshelves: aluminium. The heating mat is vulcanised to the underside of the thermoshelf and
covered with stainless steel; it consists of Silicone rubber.
• Thermoshelves: stainless steel (Mat. Ref. 1.4404). The heating mat is vulcanised to the underside of
the thermoshelf and covered with stainless steel; it consists of Silicone rubber.
• Connector between thermoshelf and electrical socket in rear wall: Ryton R4 (GF PPS plastics)
and PEEK-GF30
• Seals in solenoid valves and electrical sockets: fluoride rubber FKM/FPM (Viton)
• Door seal: Silicone rubber
The load for the vacuum drying oven must be carefully evaluated for its chemical compatibility with the
above materials.
A table listing about the compatibility of all these materials can be requested from MEMMERT.
