b) Connecting to Field Wiring Terminals
Make sure to use M3 crimp terminals (round shape) that are appropriate for the size
of the wire. Put installation covers at each crimp when connecting to the field wiring
terminals as shown in the following figure.
Make sure that the minimum clearance for air circulation is provided on both sides of
each crimp terminal by checking that the terminals are parallel to the barriers
between the terminals.
When connecting to field wiring terminals, always use round shape crimp terminals for
M3 screws and mount insulation cover at each crimp.
If bare wire are used, an electric shock or a short-circuit if the wires become
loose.
c) Protective Fuses
When the output modules are used, install fuses to the circuit to protect the output
circuit. Use a fuse with a current rating of 2A or less, which meets the specifications
described in IEC 1272 Sheet 2.
Recommended fuse: 217000 Series (manufactured by Littelfuse Inc.)
