Chapter 2 Install the Controller
1. Remove the key from the keyswitch.
2. Use your thumb to press down on the black release and pull the ESM away
from the controller.
Install an Energy Storage
Module (ESM)
Table 10 lists which ESMs are compatible with which GuardLogix controllers.
IMPORTANT
The next step depends on which of the following conditions applies to
your application:
• If you are removing the ESM from a powered controller, go to step
2.
• If you are removing the ESM from a controller that is not powered,
either because the chassis power is turned off or the controller has
been removed from a powered chassis, do not remove the ESM
immediately.
Wait until the controller’s OK status indicator transitions from
Green to Solid Red to OFF before you remove the ESM.
After the OK status indicator transitions to OFF, go to step 2
.
