One XRM-24(E) transformer is supplied standard with the control panel. An optional second XRM-24(E) transformer can be ordered and installed to provide maximum system power. Install the transformers in the locations indicated in the following illustration.

1.When the location is dry and free of construction dust, install the chassis/ transformer/circuit board assembly.

2.Mount the chassis to the backbox by aligning the two mounting tabs with the slots in the backbox, then position the two mounting hole tabs over the studs with nuts located in the upper portion of the backbox.

3.Slide the tabs located on the bottom of the chassis into the mounting slots in the backbox by pressing the chassis down.

4.Secure the chassis to the backbox by tightening the two mounting nuts (#10-32) at the top, and to ensure proper grounding, use a 3/8” nut driver or socket.

5.If the main circuit board is not already attached to the chassis, install it by positioning the ten mounting holes over the studs on the chassis and secure with the supplied screws.

6.Connect the Standard XRM-24 Transformer plug to Transformer 1 Connector J10 on the FACP main circuit board

7.Connect the Optional XRM-24 Transformer plug to Transformer 2 Connector J11 on the FACP main circuit board.
