2.2 Mounting Optional Transformer/Remounting Chassis

One XRM-24B(E) transformer is supplied standard with the control panel. An optional second
XRM-24B(E) transformer can be ordered and installed to provide maximum system power. Note
that the XRM-24B and XRM-24BE are only suitable for use with MS-9200UDLS(E) with a main
circuit board assembly number 9200UDLS-PCX Rev Y, where "X" and "Y" can be any letter or
number. Install the transformers in the locations indicated in the following illustration.
1. The standard transformer is premounted to the chassis. If the optional second transformer has
been ordered, mount it to the chassis as illustrated below.
The chassis does not need to be removed to install the optional transformer.
2. When the location is dry and free of construction dust, install the chassis/transformer/circuit
board assembly.
3. 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.
4. Slide the tabs located on the bottom of the chassis into the mounting slots in the backbox by
pressing the chassis down.
5. 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.
6. 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.
7. Connect the Standard XRM-24B(E) Transformer plug to Transformer 1 Connector J10 on the
FACP main circuit board
8. Connect the Optional XRM-24B(E) Transformer plug to Transformer 2 Connector J11 on the
FACP main circuit board.
9. Complete the installation as detailed in the following sections.
