4) Wiring
(1) Caution for wiring
•Make sure that external input signal of the mixture module of AC and analog I/O is not affected by induction noise or occurs
from the AC through using another cable.
•Wire is adopted with consideration about peripheral temperature and electric current allowance. Thicker than Max. size of
wire AWG22 (0.3 ) is better.
•If wire is put near to high temp. radiated device or contacted with oil for a long time, it may cause of electric leakage so that
it gets broken or miss-operation during wiring.
•Be sure to connect with care of polarity while connecting to external 24V DC power supply.
•In case of wiring with high voltage line or generation line, it makes induction failure so then it may cause of miss-operation
and out of order.

b) Analog output
*1 : Be sure to use two-core twisted shield wire.
* Be careful to use that analog output is 1 channel.
