2. Approvals
Conformity with the Directive 89/336/EEC Electromagnetic Compatibility (EMC)
has been assessed by application of standards EN 61000-6-2 (industrial immunity)
EN 61000-6-4 (industrial emission).
1. Safety
General:
Before using this unit, read this manual completely and gather all information on
the unit. Make sure that you understand it fully. Check that your application does
not exceed the safe operating specifications for this unit.
Before installation, maintenance or modification work:
Prevent damage to internal electronics from electrostatic discharges (ESD)
by discharging your body to a grounding point (e.g. use of wrist strap).
Prevent access to hazardous voltages by disconnecting the unit from AC/DC
mains supply and all other electrical connections.
Installation:
This unit should only be installed by qualified personnel.
This unit should only be installed in a “restricted access area”, for example a
lockable cabinet where access is restricted to service personnel only.
This unit is intended for permanent connection to the AC/DC mains supply.
The power supply wiring must be sufficiently fused, and if necessary it must be
possible to disconnect manually from the AC/DC mains supply. Ensure compliance
to national installation regulations.
Units with the rated voltage exceeding 42.4 V peak or 60 VDC, are defined as
class I equipment with a protective earthing conductor terminal.
Units with the rated voltage up to 42.4 V peak or 60 VDC, are defined as class III
equipment and shall be separated from hazardous voltage by double or reinforced
insulation.
This unit uses convection cooling.To avoid obstructing the air flow around the
unit, follow the spacing recommendations (see Installation section).

3. Introduction
The TD-29P is designed for communication on 2-wire copper cable (twisted pair).
Multidrop or point to point half duplex communication is possible at baud rates,
9600 bit/s and 19.2 kbit/s.
The TD-29P is easy to configure for different operating conditions with DIP-switches.
Character format, baud rate, transmission level and DCD detection level can be selected.
DTE-equipment can be connected through an RS-485 interface.There are two baud rate
settings.The maximum bus length in multidrop configuration is dependent on the number
of units connected.
The TD-29P is designed to be used on dedicated lines and is not approved to
European standard CTR-15 (2-wire leased line).
