SAFETY AND COMPLIANCE
ELECTROMAGNETIC COMPATIBILITY (EMC)
This is a class A product. In a domestic environment this product may cause radio interference in which case the user
may be required to take adequate measures.
The Ultimaker 2 Extended can in very rare cases temporarily loose display function caused by ESD. Display function can
be fully restored by turning the machine o and then on again.
The EMC test report of the Ultimaker 2 Extended is available on request at info@ultimaker.com.
ELECTRICAL SAFETY
The Ultimaker 2 Extended operates on 24 volts (Extra-low-voltage) and is therefore outside the scope of the low-
voltage directive. The power supply meets all CE mark regulations and is protected against short-circuit, overload, over
voltage and over temperature. For more information concerning electrical safety aspects we refer you to the Mean Well
EC-Conformity Declaration for the GS220AX power adapters.
Only use the Ultimaker 2 Extended with power supplies and cables supplied by Ultimaker B.V..
CAUTION: Always unplug the printer before doing maintenance or modifications.
MECHANICAL SAFETY
The Ultimaker 2 Extended contains many moving parts, but the stepper motors do not have enough power to cause
serious injuries and moving gears have been covered. Still, it is advised to only reach in the machine when it is turned
o.
CAUTION: Always unplug the printer before doing maintenance or modifications.
RISK OF BURNS
There is a potential risk of burns, as the print head can reach temperatures of up to 260°C and the heated bed of up to
120°C. The nozzle of the print head is mostly surrounded by an aluminum cover to prevent contact, but still we advise
against reaching in the machine when the print head and/or heated bed are hot.
CAUTION: Always let the printer cool down for at least 30 minutes before doing maintenance or modifications.
HEALTH
The Ultimaker 2 Extended is designed to print with PLA and ABS filaments. The use of other materials is at your own
risk.
When printing ABS, small concentrations of Styrene vapor can be released. This can (in some cases) cause headaches,
fatigue, dizziness, confusion, drowsiness, malaise, diculty in concentrating, and a feeling of intoxication. Therefore
good ventilation is required, and long term exposure should be avoided. It is advisable to use a fume hood (with active
carbon filtering for ductless extraction). Fume extraction is mandatory for use in oces, classrooms and alike.
Printing pure PLA is considered safe, although good ventilation is still advised for possible unknown vapors released
from coloring dyes in colored PLA.
CAUTION: Only use your printer in a well-ventilated area.
