7.3.4 Return Bypass Switch to OPEN,
800--1200 Amp Models
This procedure explains how to return the bypass switch
handle to the OPEN position. The bypass handle must
be in the CLOSED position (yellow indicator on
NORMAL or EMERGENCY) and the isolation handle
must be in the CONN position (window). See
Figure 7-49, Figure 7-50, and Figure 7-51.
Note: You can only bypass to the same source that is
connected to the ATS. A solenoid interlock
prevents incorrect operation.
