Cutler-Hammer Automatic Transfer Switch Wiring Diagrams

Directions for Use The drawing package can be used a s a point to point wiring diagram for maintenance and diagnostic purposes for Solid State Logic SPB Transfer Switches, all voltages.

This document contains the following wiring infonnation:

Pagel Basic Solid State Intelligence Panel Wuing exclusive of added option functions

Page 2 Power Switching Panel basic wiring exclusive of added option functions.

Pages 3 - 18 Wiring for optional functions

Page 19 Legend Sheet describing symbols used throughout this document

Note: Unnumbered sheets may be added to this document on specific occasions to illustrate custom options additions per order instructions.

All transfer switch units will be standardly wired as indicated by Pages I , and 2. The Intelligence Panel and Power Panel are interconnected via keyed plug/socket connectors (P1-SIIP2-S2). Your specific unit may be equipped with certain optional functions as noted which require additional wiring as shown on pages 3 - 18.

Wiring for optionally added functions will typically interface with the basic unit wiring (pages 1-2) which should be used as the base reference.

Note: BOLD lines on option wiring indicate components and wiring added to the basic wiring diagram to accomplish that specific option function.

Cutler-Hammer Automatic Transfer Switch

Standard Features

Test Pushhutton Simulates a power failure in the logic. Will cause the Generator to start. and load to transfer to the Emergency Source.

Undervoltage Protection on NORMAL (All phases) Monitors the voltage 00 the NORMAL Source for an uodervo1tage condition. Should the voltage drop below a preset Dropout. the generator is started and transfer to the EMERGENCY Source takes place.

Engine Start Contact Contact that provides a closure to Engine Controller when the NORMAL Source fails.

Logic Disconnect Plugs provided to disconnect the logic circuitry for maintenance purposes.

Auxiliary Contacts Auxiliary contacts integral to the switching devices rated at 120 VAC, 10 amps. These may be applied for customer use, and may be applied to certain customer specified options.

Fully Rated Neutral A fully rated solid neutral is supplied on all two and three pole switches. All four pole switches are supplied with switched neutral contacts of identica1 construction and rating as the power poles.
