2-2 WIRING
Check terminal Nos. on the rear panel described on Page 6 and correctly wire the cables.
2-2-1 Terminal Board
• Remove the cover from the terminal board before conducting required wirings.
• It is recommended to attach press-fit terminals to the connecting wires.
Use the press fit terminals having the size equivalent to 1.25-3.
• After completing wirings to the terminal board, do not forget to put a cover on the terminal board.
2-2-2 Connecting Power Supply
• Do not forget to check that power voltage is from 100 to 240 VAC (±10%) and use the cable with pressure
proof capacity having more than power supply voltage.
• For DC power supply (Optional), check the DC voltage is from 10 to 30 VDC (8W).
Note: Although the WGI-400A may be operated with power supply voltage exceeding the
allowable power voltage range, the operation may not be guaranteed Always use the
WGI-400A within the specified power voltage range.
Note: Control input/output and analog output terminals has a tightening torque of 0.5 N･m or
less.
2-2-3 Connecting Transducers
• Connect transducers to terminals A to E as described in the following.
(Cable colors are KYOWA's standard color codes.)
A: Bridge excitation + side (Red)
B: Bridge output - side (White)
C: Bridge excitation - side (Black)
D: Bridge output + side (Green)
E: Shield
+: TEDS (+)
-:
TEDS (-)
Note: Do not connect the power cable to the TEDS terminal.
• Use as short as possible 4-conductor shield cable (TEDS: 6-conductor cable) for transducer wiring.
In addition, locate the transducer far apart from power lines and wirings interfered with noise.
