CLIP 5115919 - Caterpillar

Introduction
This Special Instruction provides information in order to improve the overload sensing capabilities on the above listed products. Moving the "CT" to the positions that are shown in this Special Instruction will allow the overload protection device to better monitor the distribution panel. This will prevent users from accidentally overloading the generator with a single-phase load.Important Safety Information
Work safely. Most accidents that involve product operation, maintenance, and repair are caused by failure to observe basic safety rules or precautions. An accident can often be avoided by recognizing potentially hazardous situations before an accident occurs.A person must be alert to potential hazards.

Illustration 1 g01922158
Remove the current transformers from there current positions of "T1", "T2", and "T3". Refer to Illustration 1.
Illustration 2 g01922254
Install the transformers that were removed in Step 1. Be sure that the "CT's" are placed with old "T1" going to the new position of "T7", the old "T2" going to the new position of "T8", and old "T3" going to the new position of"T9".Note: Reference the wiring diagram for overload setpoints. The settings on the wiring diagram are for 100:5 current transformers. If the current ratio for the transformer is different, please contact DSN.
