A monitor port is provided at the rear side of the combiner products
DEV 2404, DEV 2408, DEV 2416, DEV 2428 and of the splitter products
DEV 2405, DEV 2409, and of the DEV 2417 carrying the combined output
signal or the split input signal at a reduced level. Except the DEV 2404 and
the DEV 2405, these products are delivered in a compact 1 RU chassis.
The housings of the combiner units or of the splitter units applied for the
DEV 2404, DEV 2405, DEV 2441, DEV 2442, DEV 2443, DEV 2461,

4.2 INSTALLATION OF THE PRODUCT
4.2.1 Mechanical Integration of the Product in a 19" Rack
For the integration in a 19" rack, the lightweight devices DEV 2404,
DEV 2405, DEV 2441, DEV 2442, DEV 2443, DEV 2461, DEV 2462, and
DEV 2463 can be directly fixed to the rack using the four rack mount flanges.
For the integration of a DEV 2408, DEV 2409, DEV 2416, DEV 2417,
DEV 2428, or of a DEV 2432 the rack slots must be prepared with rails for
the chassis. After inserting the chassis in the rack, fix the chassis with four
screws to the rack at its rack mount flanges.

DEV 2443, DEV 2444,
DEV 2462, & DEV 2463 DEV 2408, DEV 2416,
& DEV 2428
The devices DEV 2404, DEV 2405, DEV 2441, DEV 2442, DEV 2443,
DEV 2461, DEV 2462, and DEV 2463, are delivered with a grounding cable
of ~200 mm length already assembled to the grounding bolt (G, left in the
figure above) of the product, which is located on the left at the rear side of
the panel. The open end of this grounding cable provides a ring tongue
terminal. It is recommended to assemble this cable end to a point of the rack
providing ground potential.
The grounding bolt of the DEV 2408, DEV 2409, DEV 2416, DEV 2417,
DEV 2428, and of the DEV 2432 is located on the left at the rear side of the
chassis. It is recommended to connect these products to the 19" rack via an
external grounding cable. To assemble the grounding cable to the grounding
bolt (G, right in the figure above), please take off the upper nut and the first
washer and connect the grounding cable, which must have a ring tongue
terminal matching for the M4 fastening bolt. Then the washer and the nut
have to be tightened again.

4.2.3 Connection of RF Signal Cables
Please refer to the product drawings provided in chapter 3.1 for the location
and for the functionality of the different RF connectors on a combiner or on a
splitter and –if applicable- for the naming of the single combiner/splitter units.
Apply strain relieves to the external RF cables which are to be connected in
a way that the connectors of the device are not stressed mechanically.
When connecting RF cables to the chassis, each connector is to be
tightened with a torque wrench. The torque applied to 75 Ohm F connectors
should not exceed 4.5 Nm (39.8 lbf-in).
Note:
For the products of this series, female precision F connectors are
applied. Make sure that the applied connectors are male precision
F connectors (with thin inner conductor).
Recommendation for the input wiring of a combiner DEV 2404,
DEV 2408, DEV 2416, DEV 2428, DEV 2432, DEV 2462, and DEV 2463:
Best signal quality is achieved by connecting the signal sources
symmetrically to the input ports:
●1…4 of the (each) 4:1 combiner (unit);
●1…4 and 5…8 of the (each) 8:1 combiner (unit);
●1…4 / 5…8 and 9…12 / 13…16 of the 16:1 combiner; and
●1…4 / 5…8, 9…12 / 13…16 and 17…20 / 21…24, 25…28 / 29…32
of the 32:1 combiner;
and by connecting impedance matched loads to the unused input ports
of the (each) combiner (unit). The latter applies for the combiner units of
the DEV 2461, as well.
Recommendation for the output wiring of a splitter DEV 2405, DEV 2409,
DEV 2417, DEV 2442, and DEV 2443: Best signal quality is achieved by
connecting the signal receivers symmetrically to the output ports:
●1…4 of the (each) 1:4 splitter (unit);
●1…4 and 5…8 of the (each) 1:8 splitter (unit); and
●1…4 / 5…8 and 9…12 / 13…16 of the (each) 1:16 splitter (unit);
and by connecting impedance matched loads to the unused output ports
of the (each) splitter (unit). The latter applies for the splitter units of the
DEV 2441, as well.
4.3 MAINTENANCE OF THE PRODUCT
The product is maintenance-free.
Cleaning of the surface of the chassis should be done carefully with a dry
lint-free cloth.

5 OPERATION OF THE PRODUCT
After going through the installation steps as described above, the device is
ready to use.
Due to the structure of this series of passive combiners/splitters, there is no
need to interact with the device after the installation. No indicators and no
actuators are installed which need to be operated or to be maintained.
