2.1 Installation And Replacement
The controller is hot swappable. It can be removed and installed with the system operating.
2.1.1 Pre-Steps
1. Performing this procedure may activate external alarms. Do one of the following: 1) If possible, disable these
alarms. 2) If these alarms cannot be easily disabled, notify the appropriate personnel to disregard any future alarms
associated with this system.
2. Connect an approved grounding strap to your wrist. Attach the other end to a suitable ground.
2.1.2 Controller Removal
1. Loosen the captive fastener securing the top of the latch mechanism to the front of the controller. Pull the top of the
latch mechanism away from the controller (this will retract the latch mechanism located on the underside of the
controller). This unlocks the controller from the shelf. Refer to Figure 2-1.
