●About the signal I/O terminal block
RoHS-Compliant Product
The parts and attachments (including the operation manual, packaging box, etc.) used for this unit are
compliant with the RoHS Directive restricting the use of hazardous substances with regard to adverse
effects on the environment and human body.
What is RoHS?
It is an abbreviation for Restriction on Hazardous Substances, which is implemented by the
European Union (EU). The Directive restricts the use of six specific substances in electric and
electronic equipment handled within EU borders. The six substances are lead, mercury, cadmium,
hexavalent chromium, PBB (polybrominated biphenyls), and PBDE (polybrominated diphenyl
ethers).
For connection to the signal I/O terminal block, wire correctly after checking the
signal names and terminal block numbers.
Also, turn off the power of the main body before connection / wiring to the signal
I/O terminal block.
CAUTION Misuse may cause the risk of injury to
persons or damage to property.

INSTALLATION & CONNECTION
Chapter
22-1. Installation
To install the F377A into a control panel, use the following procedure.
1. Make a hole in the panel according
to the panel-cut dimensions.
2. Remove the screws (two), and
remove the guide rails from both
sides.
* Do not use other screws than
those installed to the F377A body.
3. Fit in the F377A from the front of
the panel.
4. Install from the rear the guide rails
having been removed from both
sides in Step 2, and fix them with
the screws (two).
2-2. Connection
■Power input connection
Connect the positive (+) side of the power source to
the red screw side of the terminal block on the back
of the F377A, and its negative (-) side to the black
screw side. The input voltage is 24V DC(±15%).

How to connect
1. Strip 5mm of the covering of the wire to be
connected.The size of connectable wires is
from 0.21 to 3.31mm2(AWG12 to 24).
2. Twist the tip to such an extent that it will not spread out.
3. Loosen the screw with a screwdriver to open
the connection hole.
A Phillips screwdriver 3 to 3.5mm #1 in shaft
diameter is recommended.
(Precision screwdriver, etc.)
4. Insert the wire into the connection hole so as
not to let the tip spread out.
5. Tighten the screw with the screwdriver.
0.5Nm of tightening torque is recommended.
6. Lightly pull the wire to make sure that it is securely clamped.
7. Insert the wire-connected plug into the
F377A body, and tighten the screws (two).
How to remove the terminal block
1. Loosen the screws (two) with a screwdriver.
2. Remove the terminal block by giving it a
strong pull.
