TROUBLESHOOTING APPENDICES INDEX
The precautions on the connection of the power cables are described below.
CAUTION
Be sure to ground the FG terminals and LG terminals to the protective
ground conductor.Not doing so could result in electric shock or erroneous
operation.
Use a solderless terminal with insulation sleeve for wiring of a terminal
block.
Use up to two solderless terminals for a single terminal.
Use applicable solderless terminals and tighten them with the specified
torque.
If any solderlessspade terminal is used, it may be disconnected when the
terminal screw comes loose, resultingin failure.
Wire the module correctly after confirming the rated voltage and terminal
layout.
Connecting a power supply of a different rated voltage or incorrect wiring
may cause a fire or failure
Tighten a terminal block mounting screw, terminal screw, and module fix-
ing screw within the specified torque range.
If the terminal block mounting screw or terminal screw is too loose, it may
cause a short circuit, fire, or malfunctions.
If too tight, it may damage the screw and/or the module, resulting in a
drop of the screw or module, a short circuit or malfunctions.
If the module fixing screw is too loose, it may cause a drop of the screw
or module.
Over tightening the screw may cause a drop due to the damage of the
screw or module.
Be sure there are no foreign substances such as sawdust or wiring debris
inside the module.
Such debris could cause a fire, failure, or erroneous operation.
The module has an ingress prevention label on its top to prevent foreign
matter, such as wire offcuts, from entering the module during wiring.
Do not peel this label during wiring.
Before starting system operation, be sure to peel this label because of
heat dissipation.
Install our PLC in a control panel for use.
Wire the main power supply to the power supply module installed in a
control panel through a distribution terminal block.
Furthermore, the wiring and replacement of a power supply module have
to be performed by a maintenance worker who acquainted with shock
protection.
(For the wiring methods, refer to Section 10.3.)
