3.3.7 Applications in North America
For applications for the North American market special care must be taken
with the approval of the individual components of the system SmartWire-DT.
3.3.7.1 Current carrying capacity of the SmartWire-DT connecting cable in accordance with
NFPA 79
If the SmartWire-DT connection system is used for applications in North
America, the maximum current carrying capacity of the SmartWire-DT con-
necting cable is reduced from 3 A to 2 A.
If, due to the application, the maximum current carrying capacity of the
SmartWire-DT connecting cable exceeds the value 2 A, this can be compen-
sated by means of additional SmartWire-DT power feeder modules
(￫ Chapter 1 “EU5C-SWD-PF1-1, EU5C-SWD-PF2-1 power modules”, page
15).
3.3.7.2 DOL starter
With the use of DOL starters in the North American market various special
features must be observed that are based on market practices and the asso-
ciated Standards.
DANGER
The safety and redundancy circuit architectures for switching off
drive groups described here, in terms of the safety categories
that can be achieved, are approved when using the following
SmartWire-DT coordinators and SmartWire-DT components:
• EU5C-SWD-CAN
• EU5C-SWD-DP
• EU5C-SWD-PF1-1
• EU5C-SWD-PF2-1

A comprehensive overview of the special North American fea-
tures is provided by the publication “Special Conditions for the
use of motor-protective circuit-breakers and motor starters in
North America”, VER1210+1280-928EN.
