Electrical equipment
Electrical and control equipment in the machine are located in a separate space. Live components are
insulated or guarded so that they cannot be accessed by direct contact. Conductive elements are
connected with electric shock insulation. The electrical equipment zone is protected by a fixed guard
with the corresponding warning pictogram placed on it.
The liquid cooling system associated with the extruder modules is a close-loop system.
The connectors are fitted with check valves to prevent leakage once disconnected.
