InsulGard System Installation and Start Up Guideline
16
2) Diagram of the main required connections to Insulgard
Figure 1-13 Main connection to InsulGard
3) IPDS sensors installation specifics
a) Be sure to install the capacitors on the HV Phase leads and not on the neutral side of the winding.
b) If a motor has surge capacitors, install the HV connection on the motor winding side of the surge capacitors.
See diagrams below.
