Requirements for the assembly site
Ambient temperature :
5°C to 40°C
When the ambient temperature exceeds or falls below that
specified, the electrical and mechanical components may be
damaged, and performance data changed to an unknown
extent.
Humidity :
Maximum relative humidity 80% at temperatures up to 31°C,
linear decline down to 50% relative humidity at 40°C
At a higher humidity, the electrical and mechanical compo-
nents may be damaged, and performance data changed to an
unknown extent.
Altitude of assembly site :
Max. 2000 m above sea level
Assembly / transport fastening
SM
Install the AS300 only on a stable laboratory bench to avoid
unpleasant transmission of vibrations.
Undo the hex nut SM with an open-ended spanner until
the sieve disk can be moved freely
Undo the wing screws A (transport fastening) with hex
nuts
Install the appropriate sieve clamping unit
Retain wing screws A with hex nuts (transport fastening)
for transport at a later date.
Re-using the transport fasteners
Screw the hex nuts fully onto the wing screws
Screw the wing screw through the sieve disk into the
housing
Turn the hex nut downwards and tighten with an open-
ended spanner until the sieve disk can no longer move
Mechanical components can be damaged if operated with the
transport fasteners or transported without transport fasten-
ers.
Electrical connection
Refer to the data plate for the voltage and frequency at
which the AS300 control is to be operated.
Ensure that the values shown there correspond to those
for the local power supply.
Use the supplied power cord to connect the AS300 con-
trol to the power supply.
When plugging the power cord into the power source,
use an external fuse corresponding to the local regula-
tions.
Failure to observe the values on the data plate can cause
damage to the electrical and mechanical components.
