5.2 How to connect wires
Before carrying out wiring, turn off the power and check that the cables to be connected are not alive
because there is a possibility of electric shock.
NOTE:
All wiring must confirm to appropriate standards of good practice and local codes and
regulations. Wiring must be suitable for Voltage, Current and temperature rating of the system.
Provide power from a single-phase instrument power supply. If there is a lot of noise in the
power line, insert an insulating transformer into the primary side of the line and use a line filter on
the secondary side. Do not place the primary and secondary power cables close to each other.
Use repeater after each set of 32 instruments connected in RS-485 Communication.
Unused terminals should not be used as jumper points as they may be internally connected,
which may cause damage to the unit.
Use >250V-1Amp Cable for Power Supply.
Supply voltage must be below maximum voltage rating specified on the label.

Note: - Consider RS485 Connection Detail for DDU-TM-44/DDU-44 or DDU-TM-46/DDU-46
same as above figure 15
In case of RS-232 Output base master unit, external RS-232 to RS-485 Connector required, and
it will be connected direct in case of RS-485 output from Master.
