Power connection
Note
1. Before connecting terminal, power must be shut off.
2. Use ring type terminal against oscillation, impact, etc.
3. YT-2300 series (except PTM included type) use DC 4-20mA as power. Minimum
supply current is 3.2mA (standard type) and 3.8mA (Hart type) and Maximum supply
current must not be exceeded 24mA.
4. In case of PTM type, additional power should be supplied to PTM separately. Supply
voltage is 9-27V and must not be exceeded 30V.
5. In order to protect the product the ground terminals should be grounded.
6. Use twisted cable which conductor sectional area is 1.25
and is suitable for 600V
㎟
as on conductor table of NEC Article 310. Outer diameter of cable should be 6.35-10mm.
Use shield wire against electromagnetic wave and noise.
7. Do not install the cable near the equipment such as high-capacity transformer or motor
generating noise.
The following is terminal part of YT-2300 series.

Terminal connection of current input signal
3. Insert a cable through cable connector in YT-2300.
4. Use ring type as cable terminal in order not to come out.
5. Insert terminal bolts in terminal holes of cable and lock them with + terminal and -
terminal each on terminal plate. Tighten terminal bolts with 1.5Nm (15kfgcm) torque.
6. Be sure not to change the polarity of terminal.
Terminal connection of feedback signal
1. Open cover by loosening 4pcs of M4 bolts of product cover.
2. Loosen terminal locking bolts of feedback signal for position transmitter on terminal
plate.
