[WIRING PRECAUTIONS]
z
Before installation or wiring, be sure to shut off all phases of the external
power supply used in the system.
If the power is not disconnected at all phases an electric shock or product
damage may result.
z
Always earth the FG terminal to the protective earth conductor. Otherwise
there will be an electric shock or misoperation.
z
Perform correct wiring for the module according to the product’s rated voltage
and terminal arrangement. Connecting to a power supply different from rating
or miss-wiring may cause fire and/or product failure.
z
Ensure that no foreign matter such as chips and wire-offcuts enter the module.
Foreign matter can cause a fire, failure or malfunction.
z
Be sure that the communication cable connected to the module is kept in the
duct or is fixed with cramps.
Failure to do so may cause a damage to the module or cables due to
dangling, shifting or inadvertent handling of cable, or malfunction because of
bad cable contacts.
z
Do not install the control lines together with the communication cables, or
bring them close to each other. Failure to do so may cause malfunctions due
to noise.
z
When disconnecting the communication and power supply cables from the
module, do not hold and pull the cable part.
Disconnect the cables after loosening the screws in the portions connected to
the module.
Pulling the cables connected to the module can damage the module and
cables or can cause a malfunction due to a cable connection fault.
