|
- Indoor installation, free from corrosive or flammable gases. |
||
Balancing |
||
|
- Grade "R" |
||
Concentricity and perpendicularity of the axis / flange |
||
|
- grade "N" (normal) - according IEC 72 - DIN0530 |
||
Shaft output |
||
|
- with key, with coaxial threaded hole |
||
Brake |
||
|
- optional. Spring parking brake, 24VDC power supply with polarity not determined. Brake engaged in the absence of power. Braking torque greater than motor Tn |
||
Connections and cables |
||
