4.2 Terminal box and current sensing transformer connections
Make sure that the black lead from the sensor module is always connected to the terminal 2 (installation is already done in the
factory). Black lead from sensor module must be always connected to that terminal of which power supply cable is lead through current
sensor.
4.2.1 Installation of current sensing module
One of the motor power leads passes through the "toroid" (current sensing
module). Information from the current sensing module is used to determine
running amps, power consumption and locked rotor conditions. There are 3
voltage sensing leads attached to the motor terminals and connected to the
sensor module. Two of the leads are white, and one is black. For proper
calculation of power factor and motor power it is necessary for the black voltage
sensing lead and the power lead through the current sensing module to be
connected to the same motor terminal.
Class II transformers have a maximum VA (Volt-Ampere) rating of less than 100
and a maximum secondary output of 30 VAC.
