2 Technical data summary
MEMMERT appliances are electrically heated and thermostatically controlled. Series
UM/SM have natural air circulation whilst series ULM/SLM have fan assisted circulation.
A PT100 DIN B, DIN 43 760 measures the temperature in the working chamber.

When the fan of the models ULM / SLM is switched on, the working
temperature can be set from 10°C degrees above ambient up to the
nominal temperature = maximum temperature (according to rating plate).

Protection of
the oven, the
environment
and the
contents of the
oven
The contents of

TWW
(adjustable overheat controller)
takes over control of oven if
temperature is exceeded.
Special safety
measures required
depending on the
purpose for which
the oven is used
2.1 Electrical
supply
50 or 60 Hz. Adequate insulated supply which incorporates earth conductor according to
EN 61010, Protection IP 20, no humidity protection according to DIN 40 050. Interference
suppression Grade N according to VDE 0875, limiting values of the class B, part one.
A fuse 250V/15A quick is used for oven protection (in ovens with 400V 3N~ power supply
3 fuses).
Before current-connection please compare label on the oven and instructions of
your local current supplier.
(e.g. in Germany, DIN VDE 0100 with FI - safety device).
