Figure 8, p. 16 illustrates an application with more than two expansion modules, which requires
the use of a PM014 power supply module. In this scenario, the UC600 only provides power and
IMC communications for the first two expansion modules.
Observe the following when using this method:
• The IMC harness/IMC terminals that connect the second expansion module to the PM014
must not transmit 24 VDC. Remove the bottom (red) wire from the IMC cable harness.
• The PM014 can provide power for an additional 11 expansion modules.
• The UC600 provides 24 Vdc power for the first two expansion modules that are positioned on
the left side as shown in the figure below.
• The PM014 provides power for the two expansion modules that are on positioned on the right
side of the PM014 in the figure below.
• The transformer provides 24 VAC input power for the UC600 and the PM014.
NNoottee:: The above guidelines also apply when using a Tracer UC400 controller.

Figure 9, p. 17 illustrates an application where an XM70/90 is used to provide power for two
additional expansion modules. On this link a total of four expansion modules can be added.
• VAC input power is provided by the transformer (for UC600 and XM70/90)
• Maximum of two expansion modules can be powered by the UC600 24 VDC through the IMC
cable.
• Maximum of two expansion modules can be powered by the XM70/90 through the IMC cable.
• The IMC cable between the expansion module powered by the UC600/400 DC power and the
XM70/90 must have the 24 Vdc wire removed.
• Connect the modified IMC cable between the XM30 that is powered from the UC400/UC600
and the XM70/90.
• The XM70/90 can power up to two XM30 or XM32 expansion modules.
