Caution:
The external input signals are separated by basic insulation from power supply for the unit.
The external input signals should be separated by supplementary insulation from where user may touch in case that it is installed where
user may touch.
Connect the terminals by using the ring terminals and also insulate the cables of adjoining terminals when wiring to terminal block.

Demand control is available by connecting remote switches with terminal No.10 - 14.
Make sure to use the non-voltage switch (for the remote switch)
Remote switch cable length : Maximum 10m
Remote switch : Minimum applicable load DC12V, 1mA
• 4-20mA / 1-5V / 0-10V / 0-10kΩ
1Use 4-20mA / 1-5V / 0-10V
Connect the transmission cables to No. 3 and 4 on the terminal block (TB62).
No. 3 on the terminal block(TB62) : Plus side
No. 4 on the terminal block(TB62) : Minus side (Reference side)
