OFF position.
2. Open the ATS enclosure and manually transfer the
ATS to utility. (Open the emergency breaker and
close the utility breaker. See Section 2.7 for

on the door should be off.
6.4 Service Disconnect to OFF
Operation
Note: This section describes service disconnect and
reconnect procedures for transfer switches that
use the Service Disconnect to OFF position. Go
to Section 6.3 for transfer switches that use the
Service Disconnect to Emergency position.
The two-position service disconnect switch disconnects
the source from the load, by transferring to the OFF
position, and inhibits further transfer.
The service disconnect switch and utility disconnected
lamp are located on the enclosure door. See Figure 6-5
for the typical service disconnect switch location. See
Figure 6-6 for the service disconnect switch decal.
When the switch is in the SERVICE DISCONNECT
position, the controller display shows SERVICE
DISCONNECTED and the utility disconnected lamp on
the enclosure door illuminates if either source is
available.
