INFORMATION

This manual is conceived in a way to offer to the personnel involved in project and safety verification 
of a machine all information concerning characteristics, working conditions, application limits hazards 
and cautions about X-PLUS ET series stepping motor drives. The knowledge of this information is 
essential for a correct project of machines, apparatus and systems in which the drives are used; it is 
strongly  recommended  not  to  start  any  operation  with  the  drives  before  you  have  completely  read 
and  understood  the  content  of  this  manual;  if  you  find  some  part  of  this  manual  not  completely 
understandable  or  lacking  regarding  your  particular  application,  do  not  hesitate  to  contact  directly 
R.T.A. that can provide, if necessary, further information in order to make the user able to design his 
machine and the related safety systems in the best way. Take into account that an incorrect use or 
installation,  a  wrong  dimensioning  of  external  safety  elements  related  with  the  drive  could  bring  to 
economical damages and also to hazards for human life.

HAZARDS AND PRECAUTIONS 

2.1 - 

 

INFORMATION

X-PLUS ET series drives are suitable to drive two phases stepping motors with 4, 6 or 8 terminals. 
(see also section 10 for more details about motor and application limits). The use of stepping motors 
with 5 terminals is not allowed. 
Their use for different purposes is not allowed. 

2.2 - 

 

WARNING!

 

X-PLUS ET series drives [UL category: Open Type Motor Drive] are power conversion equipments 
with protection degree IP20 (IEC 60529), foreseen for use in pollution degree 2 environment, with a 
working temperature range between  5°C (41 °F) and 40°C (104 °F). Thereby, they must be located 
within  a  protective  enclosure  suitable  to  maintain  the  above  mentioned  conditions.  The  position 
inside the enclosure must be chosen in a way to avoid that small tools or particles of material can 
drop  inside  the  drive  through  the  ventilation  holes. 

Avoid  absolutely  to  install  in  explosive  or 

flammable  environments.

 

Avoid  also  to  install  near  easily  flammable  materials  and 

components

; we recommend to verify that all the components located in the enclosure are realized 

using self-extinguishing materials. 

2.3 - 

 

WARNING!

 

X-PLUS  ET  series  drives  are  designed  for  use  in  general  industrial  equipments.  Do  not  use  in 
installations in which an utilization mistake or a malfunction or a failure of the drive could cause: 

  Injuries or hazards for human life  

  Property damages 

  Risks of social and public upsets
