Wiring

Pass motor leads through Motor Insight overload relay 
CT pass through. If multiple passes of the motor leads 
are required, make sure that the current flow is from 
top to bottom through Motor Insight overload relay. If 
external CTs are used, pass the 5 amp secondary of the 
external CTs through Motor Insight overload relay inter-
nal CTs. See 

Table 3A

 for wrap and CT multiplier.
