2. Note on connection

Warning
●
In case of connection with the instrument, keep strictly to the following items. If
neglected, it may cause an unexpected failure or a damage to the instrument.
D Be sure to set the power supply to OFF, when the connection is made.
D Since the terminal boards at front of the instrument is made of resin, take care not to drop
it down or not to apply strong impact.
D The electric wire which suits the terminal block of this unit is 0.08 mm

/AWG28
〜
2.5
mm
2
/AWG12.
D The electric wire bare length is 5 mm to 6 mm.
D Connecting cable with the instrument should be away from the noise source such as power
supply line and/or I/O line for control and so on as far as possible.
D
Conduit wiring should be the type of exclusive one, and avoid using with another line
together.
D All of the connections should be executed securely by referring to the Instruction manual
for the instrument.
