The optional USM2.5 status monitoring upgrade plugs into the XM Series 2 Inverter Module.
The USM2.5 can be configured for various status monitoring interfaces by setting the DIP
switch. Status monitoring interfaces are listed according to their manufacturer, along with
the associated parts in Section 3.1. The USM2.5 also accommodates a tamper switch
assembly to indicate unauthorized enclosure entries.
CAUTION: The USM2.5 PCB contains static sensitive components that could be easily
damaged if not handled properly.
When installing the USM2.5 use the following procedure:
USM2.5 Installation Procedure:
1. Refer to Section 2.1 for Inverter Module removal.
2. Install the USM2.5 assembly on the Inverter Module:
Tools Required: #2 Phillips head screwdriver.
a) The 2 x 9 pin Strip Connector (Fig. 2-3), must be installed onto the
Inverter Module. A properly installed strip connector will be fully
seated and firmly in place.
b) A new USM2.5 will come with a snap-on support. Position the
USM2.5 over the strip connector and the rear hole for the support
and carefully push into place. Verify the position of the strip connector,
and that the support is fully seated into the Inverter Module mounting
shield.
c) When replacing a USM2.5 the support may already be installed. If
so, align the USM2.5 over the supports and gently rock onto the
strip connector. verify the position of the strip connector, and that
the support is fully seated into the Inverter Module mounting shield.
d) Secure the top of the USM2.5 card to the Inverter Module with the
captive screw fastener. The lower portion is covered by an optional
blanking plate (Fig. 2-2) or an Internal Transponder. Use 2 #6 screws
to secure the blanking plate, or the two captive screw fasteners
with the Internal Transponder.
3. Setup the USM2.5 for proper operation (see Section 3, Configuration):
a) Before reinstalling the Inverter Module, set the DIP switch, SW1 to
the proper configuration settings for the status monitoring interface,
as per Table 3-1 (page 12). Always verify USM2.5 configuration
especially after upgrading or modifying the XM Series 2 Power
Supply.
4. Carefully reinstall the Inverter Module. Refer to section 2.1.
