UL, cUL Installation Instructions
1. Input power and output motor field wiring
shall be copper conductors, rated 75ºC.
2. Use UL listed closed-loop connectors sized
for the selected wire gauge. Install connectors
using the correct crimp tool recommended by
the connector manufacturer. Applies only to
units bus bars.
3. Table showing corresponding wire size,
terminal screw, closed-loop connector size.
Torque ratings for attachment of connector to
bus bar (see table).
4. Branch circuit protection, shall be provided
per the NEC.
For units with UL cUL, see ordering information.

LR Recommendation
LR recommendations for marine, offshore or industrial
use.
System design needs to take into account the power
supply source and the motor drive together with the
electronic soft starter. Particular features to be
considered are torque production, harmonic production
and their consequential effects and EMC. These points
are relevant for marine, off-shore or industrial use.
