Removing a Module
To remove an existing module, you must first disconnect the communications and
power cables from the existing module, and then remove the module. If you are
removing a blank module plate, there are no communications or power cables to
disconnect.
Warning Hazardous Voltages:
Hazardous voltages are
present in the control panel as long as any of the power
supplies are connected to the AC power.
1.
Power down the control panel. The frame can remain on during this

from any neighboring modules.
