Operating Instructions PMA 35001-X
The IP protection rating of the color-mixing scale in accordance with EN 60529 is
IP 43.
The device must be handled carefully in accordance with the IP protection rating.
The environment must be suitably secured.
The color-mixing scale meets all requirements for electromagnetic compatibility
(EMC). Interference stronger than the maximum values specified in the standards
(see Declarations of Conformity) should be avoided.
The casing on all connection cables as well as the casing on the wires inside the
equipment housing are made of PVC. Chemicals that corrode this material must
be kept away from these cables.
None of the components of the color-mixing scale should be exposed to ambient
temperatures outside the range of 0°C to 40°C during operation. Sufficient
ventilation must be provided, in order to avoid excessive build-up of heat.
The equipment must only be used indoors. Avoid generating static electricity
on glass and plastic parts. The color-mixing scale must be connected to the
equipotential bonding conductor using a suitable low resistance method.
All electrical circuits are earthed and electrically connected to the metal parts of
the device.
– The scale must be checked for correct function and safety by a trained and
qualified person at appropriate intervals (e.g. checking the cable for damage).
– Operating personnel must be trained to recognize faulty operating states and to
be able to initiate the necessary safety measures.
Proceed with extreme caution when using pre-wired connection cables purchased
from other manufacturers, as the pin assignments may not be compatible with
Sartorius equipment.
Only use cables and cable lengths approved by Sartorius.
– The operator is solely responsible when using cables not supplied by Sartorius.
The scale should only be opened by trained personnel with the power
disconnected. Danger to life: do not touch conductive parts of the power supply
wiring!
The scale must be installed and operated in a way that ensures that the control
unit cannot be damaged (e.g., by falling objects).
If the control unit is damaged, disconnect the device from the power supply
immediately.
A defective device may only be repaired by trained service technicians in
accordance with Sartorius guidelines. Only original replacement parts should be
used. Always ensure that the equipment is disconnected from AC power before
performing any maintenance, cleaning, or repair work.
If the equipment is opened by anyone other than persons authorized by Sartorius,
all claims under the manufacturer's warranty are forfeited. If necessary, speak to
your dealer or the Sartorius Service Center.
