  The above types for Type-E combination motor controllers are listed in compliance with both CE and UL/cUL standards. 
For more information about the accessories, refer to SINAMICS V90, SIMOTICS S-1FL6 Operating Instructions. 
Requirements for United States/Canadian installations (UL/cUL) 
Suitable for use on a circuit capable of delivering not more than 65000 rms Symmetrical Amperes, 480 VAC maximum for 
400 V variants of drives or 240 VAC maximum for 200 V variant drives, when protected by UL/cUL listed (JDDZ) fuse or 
type E combination motor controller. For each frame size AA, A, B, C and D, use 75 °C copper wire only. 
This equipment is capable of providing internal motor overload protection according to UL508C. 
For Canadian (cUL) installations the drive mains supply must be fitted with any external recommended suppressor with the 
following features: 
•  Surge-protective devices; device shall be a Listed Surge-protective device (Category code VZCA and VZCA7) 
•  Rated nominal voltage 480/277 VAC, 50/60 Hz, 3-phase 
•  Clamping voltage VPR = 2000 V, IN = 3kA min, MCOV = 508 VAC, SCCR = 65 kA 
•  Suitable for Type 2 SPD application 
•
  Clamping shall be provided between phases and also between phase and ground 
The components are subject to continuous further development within the scope of product maintenance (improvements to 
robustness, discontinuations of components, etc). 
These further developments are "spare parts-compatible" and do not change the article number. 
In the scope of such spare parts-compatible further developments, connector positions are sometimes changed slightly. This 
does not cause any problems with proper use of the components. Please take this fact into consideration in special 
installation situations (e.g. allow sufficient clearance for the cable length).
