After settlement the assembly of final unit CK of other type is possible (e.g. diode+resistor, reverse polarity, etc.)
produced by DAMEL -catalogue card K4-15-121).
" The motor is intended for feeding from the mains, start-up can be executed:
- by direct switching on the voltage on I or II speed,
- by direct switching on the voltage on I speed and start-up on II speed through starter.
" The motors adapted for work in temperate climate; after settlement the adaptation for work in tropical climate TA
or TH is possible.
COMPATIBILITY WITH REQUIREMENTS OF STANDARDS
The motors meet requirements of Directive 94/9/EC (ATEX), European harmonized standards and
domestic norms:
- norms for electrical equipment in areas of explosion hazard:
EN 50014:1997+A1:1999+A2:1999  Polish equivalent PN-EN 50014:2002U,
