Name Function
(2) ERR terminal • This is the terminal that outputs MINI-S3 link errors and self-diagnostic errors.
(See Section 4.2.10.)
(3) Power input terminal • This connects 100 VAC or 200 VAC power supply.
(See Section 4.1 for the specification and Section 6.4.2 for the connection.)
(4) Voltage sWitching • Used to set the voltage inputted to the power input terminal
terminal (See Section 6.4.2 for the connection)
100 VAC input :
Short-circuit between terminals
by
use of a jumper supplied
with the A2C.
200 VAC input : Open between terminals.
(0)
LG terminal
• For grounding of the power filter
• This has the electric potential of the half of that of the input voltage.
(6)
FG terminal
• This is connected to the shielding pattern on the printed circuit board.
POINTI
If the supply voltage to the power input terminal is different from voltage
setting of the voltage switching terminal, the following occurs.
