DISTRIBUTED I/O – PRODUCT DATA

Terminal Block Connection

NOTE: The terminal blocks are to be mounted on 1.5-inch
(35-mm) DIN rails (DIN/EN 50 022 35x15). The
mounting panel should have a min. thickness of 0.08
inch (2 mm) to provide reference potential for proper
grounding and shielding. The max. distance between
the fastening points of the rail should be 5.9 inches
(150 mm).
The L W connector module (see section "L
ON ORKS
Connector Module XSL511") can be used as an interface
between the L W bus and the Distributed I/O modules.
ON ORKS
The terminal blocks may be fitted alongside one another.
Depending upon the configuration, either one or two
termination modules are required for terminating a L
bus with FTT devices on it. See also section "LonWorks Bus
Termination Modules" on page 23 for more information on
termination.
Mounting with the LonWorks Connector Module
IMPORTANT
When mounting the terminal blocks using the XSL511
LonWorks Connector Module, the following worst-case
power consumption analysis must be performed to
determine the required transformer.
Select the worst-case max. current rating for the XSL511
based upon the max. temperature of the installation as stated
in Table 13. The electronic fuse RXE160 is applied in XSL511
with date code 9916 and higher. Ratings are as follows:

Calculate the worst-case current draw for the Distributed I/O
modules and the Excel 500-XCL5010 controller to be
connected to the transformer based on the input voltage
stated in Table 14:

connector module, however, if mounting vertically, it is re-
commended that you mount it at the bottom to ensure a good
connection of the bus in case of slippage on the DIN rail.
When mounting the terminal blocks, avoid sliding them in a
rough or sudden fashion as this might dislodge the contact of
terminal 17 of the XSL513 or of terminal 18 of the XSL514.
1. Mount the DIN rail at the desired location (vertically or
horizontally).

2. Install the 3
the rail.
3. Install the connector module onto the left end of the rail
next to the end bracket by first hooking the terminal end of
the module onto the rail and snapping it into place.
4. If necessary (e.g. in case of vibrations due to refrigerating

equipment, etc.), mount braces (see Fig. 20).
5. Install the first terminal block onto the rail.
NOTE: To avoid damage, ensure that the sliding bus con-
nector does not extend past the module's left edge.

6. Push the sliding bus connector to the left until it locks
onto the matching circuit board section on the adjacent
connector module (see Fig. 19).
7. If necessary (e.g. in case of vibrations due to re-
frigerating equipment, etc.), mount braces (see Fig. 20).
8. Lock in all other modules and connect them using the
sliding bus connector. Slide each sliding bus connector
as far to the left as possible.
NOTE: The electronics module / manual terminal disconnect
module will not fit properly on the terminal block if the
sliding bus connector is not on the left side.
9. Fit the end cover included with the XSL511 onto the last
module.
