ventilation, as shown in the figure below.
Terminal Block Dimensions
•
Use the terminals that comply with the specifications given below.
•
Set terminal wiring torque to from 5 to 7kgfcm.
•
Use wiring cables of #16 to #22 AWG.
Set terminal wiring torque to within the specified range
(0.5 to 0.7 Nm) when wiring with terminal block. Otherwise,
it may cause terminal block damage or contact defects
leading to product damage or personal injury.
Make sure to disconnect power to the controller system
before performing installation, wiring, maintenance and
cleaning. Never touch the power terminals when the power
is on. Otherwise it may cause electrical shock.
Route wires of different signal characteristics by separate
paths. Separate incoming power to the controller by a path
separate from the I/O device wiring. Shield the signal lines
to prevent noises which can cause product malfunction.
