Notes on Master Connection Diagram
(see Preceding Page):
1. All Aux. Switch contacts shown with Breaker in OPEN position and with trip unit in “non-tripped” state
(OTS switches).
2. The Spring Release accessory consists of an “SR” coil and a P.C. Board. The printed circuit provides a
.20 second pulse for the closing operation. Voltage must be removed and then reapplied for subsequent
operation.
The Latch Check Switch (LCS) acts as a “logic” input to the “SR” device. The close signal pulse will not
be sent until the breaker is reset.
3. To provide selected time delays for Short Time and/or Ground Time functions for testing or Non-Zone
Interlocking applications a jumper from B-8 to B-9 is required.
4. On breakers having Ground Fault function active, a jumper installed from B-6 to B-7 will enable Zero
Sequence Ground Fault Sensing and disable Residual Ground Fault Sensing. Inputs B-4 and B-5 will be
reassigned for Zero Sequence Ground Sensor inputs.
5. Normally open contact programmed as Relay A via Digitrip front panel (Alarm Contact).
6. Normally closed contact programmed as Relay B via Digitrip front panel (Block Close Contact).
7. Normally open contact programmed as Relay C via Digitrip front panel (Latching Contact).
8. Motor Operator Switch shown with closing spring discharged.
9. Second Shunt Trip may be installed (using A-7, A-8 contacts) in place of UVR.
