4.2 How to connect wires?
Before carrying out wiring, turn off the power to the controller 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.
For RTD input, use shielded wires that have low conductor resistance and
cause no significant differences in resistance between the three wires.
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.
Unused control 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
If cable has two parallel wires inside then isolation between them must be
2.5 KV.
