FCC NOTICE
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, these is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by tuning the equipment off and on, the user is encouraged to try to correct the interference by one or more the following measures:
-- Reorient or relocate the receiving antenna.
-- Increase the separation between the equipment and receiver.
-- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
-- Consult the dealer or an experienced radio/TV technician for help.
Caution: any modification or change not expressely approved by the party
responsible for compliance could void the user’s authority to operate the equipment.
Canadian Compliance Statement
This Class B Digital apparatus meets all the requirements of the Canadian Interference-Causing Equipment Regulations. Cet appareil numerique de la classe B respecte les exigences du Reglement
sur le material broilleur du Canada.

PRELIMINARY OPERATIONS
Mounting Instructions
The cables are attached to an encased box. Make sure that you place the box at a height of 120cm from the floor (see Figure 1).

Arranging the Cable Tubes and Junction Boxes
All the cables consist of 4 wires that must be connected in parallel from one node to the next. It is possible to link nodes in free topology, i.e. by means of a star or bus configuration.
Cabling: Recommendations
Figure 2 provides an example of a typical free topology installation.

Page 8 Arranging the Cable Tubes and Junction Boxes
If you want to mount the tubes on the surface of the walls, it is advisable to place the junction boxes under each terminal (see example in Figure 3).

• The LONWORKS
• In a free topology configuration, the sum total of the sections must not
exceed 500m
• In a bus configuration, the sum total of the sections must not exceed
2700m
• In a free topology configuration, activate the 50ohm terminator by placing
the appropriate jumper on the FTT10A plug-in of the CTU-PLG06 board inside the TemaServer
• In a bus configuration, place two terminators (with resistance values of
100ohm 1% ½W) at each end of the bus
