Take the following precautions:
● Do not attempt to dismantle the internal circuit enclosures, top heating, fusing lamps, build unit,
pr
ocessing station, or e-cabinet except during hardware maintenance tasks. In that case, follow the
instructions strictly.
● Do not remove or open any other closed system covers or plugs.
● Do not insert objects through slots in the equipment.
● Test the functionality of the Residual Current Circuit Breakers (RCCBs) every year. See
Check
the functionality of the Residual Current Circuit Breakers (RCCBs) on page 275 and Check the
functionality of the Residual Current Circuit Breaker (RCCB) on page 296.
NOTE: A blown fuse may indicate malfunctioning electrical circuits within the system. Call your
ser
vice representative (see
When you need help on page 382), and do not attempt to replace the fuse
y
ourself.
Heat hazard
Take precautions to avoid the risk of burns.
The top heating, fusing, and build chamber subsystems of the printer operate at high temperatures and
can cause burns if t
ouched. To avoid personal injury, take the following precautions:
● Take special care when accessing the printing area. Let the printer cool down before you open the
co
vers.
● Take special care with zones marked with warning labels.
● Do not place objects inside the equipment while operating.
● Do not cover enclosures while operating.
● Remember to let the equipment cool down before performing some maintenance operations.
● Wait for at least the minimum cooling time (see
Unpack the build on page 77) before extracting the
build unit fr
om the printer after printing, or unpacking parts from the build unit.
● Use the appropriate personal protective equipment (i.e. heat resistant gloves) during the powder
r
emoval process.
● If heat resistance gloves are required according to the Explosion Protection Document (EPD) or Dust
Haz
ard Analysis (DHA), it is recommended to choose them according to standard ISO/EN 13732-1
Ergonomics of the thermal environment - Methods of assessment of human responses to contact
with surfaces. Part 1: Hot Surfaces.
Fire hazard
Take precautions to avoid the risk of fire.
The top heating, fusing, and build chamber subsystems of the printer operate at high temperatures.
C
all your service representative if the built-in Residual Current Circuit Breaker (Ground Fault Circuit
Interrupter) is repeatedly tripped.
