2. General information 

 
2.1 Safety 

 

  The equipment is only designed and may only be used for the dosing of dry additives. 

Any use that is not in conformity with the instructions is considered improper and as such 
frees the manufacturer from any liability regarding damage to things and/or persons.  

  Before switching on the unit for the first time, ensure that the mains power voltage  

applied is between 80 and 260Vac. 

  Always switch off the Movacolor control cabinet and disconnect the mains power plug from 

electrical power before performing maintenance. 

  Ensure that all parts are securely fixed to the extruder or injection molding machine. 

 

  Dangerous voltages are present inside the control cabinet for up to 2 minutes after it has 

been switched off. 

 
 
2.2 Certification 

 

The Movacolor dosing unit is designed and produced in conformity with the following European 
regulations: 

•

 

 standards for machinery (health, safety, environment) 

•

  EMC (electromagnetic compatibility) 

•

  VEM (safety electric material) 

•

  98/37/EC, Annex 1(See the declaration of conformity, Appendix E) 

 

 
 

2.3 Operating environmental conditions 

 

•

  The unit must be protected against weather conditions  

•

  Operating temperature -20 to +70 degr. C. 

•

  Protection class: IP-50
