[WIRING PRECAUTIONS]
DANGER
!
Completely turn off the external power when installing or placing wiring. Not
completely turning off all power could result in electric shock or damage to
the product.
CAUTION
!
When wiring in the PC, be sure that it is done correctly by checking the
product's rated voltage and the terminal layout. Connecting a power supply
that is different from the rating or incorrectly wiring the product could result
in fire or damage.
!
Be sure there are no foreign substances such as sawdust or wiring debris
inside the module. Such debris could cause fires, damage, or erroneous
operation.
!
Solder the coaxial cable connector properly. Incomplete soldering may
cause a malfunction.
!
Tighten terminal screws to the specified torque.
If a terminal screw is not tightened to the specified torque, it the module may
fall out, short circuit, or malfunction.
If a terminal screw is tightened excessively, exceeding the specified torque,
the module may fall out, short circuit, or malfunction due to breakage of the
screw or the module.
!
Be sure to fix communication cables or power cables leading from the
module by placing them in the duct or clamping them.
Cables not placed in the duct or without clamping may hang or shift,
allowing them to be accidentally pulled, which may cause a module
malfunction and cable damage.
!
When removing the communication cable or power cables from the module,
do not pull the cable. When removing the cable with a connector, hold the
connector on the side that is connected to the module.
When removing the cable connected to the terminal block, first loosen the
screws on the terminal block.
Pulling the cable that is still connected to the module may cause malfunction
or damage to the module or cable.
