7.2.1 Bypassing the ATS,
150--600 Amp Mo dels
This procedure explains how to bypass the closed
transfer switch contacts. Bypassing is required before
the transfer switch can be tested or isolated.
D The bypass switch handle must be in the OPEN
position (green window indicator). See Figure 7-5.
D The Isolation Handle must be in the CONN
(connected) position. Check the position window
indicator. See Figure 7-6.
D The TS Connected light must be on. See Figure 7-7
and Figure 7-8.

connected to the transfer switch. A solenoid
interlock prevents connection to the wrong
source.
