Mandatory
Be careful not to let wire fragments and other
foreign matter into the module and units. They
could cause a fire, failure, and malfunction.
Mandatory
For module wiring, use sheathed crimp
terminals or cover the terminals with tape so the
conductors will not be exposed.
Handle the terminal board cover with care not
to let it drop or be damaged. After wiring the
module, place the terminal board cover
securely over the terminal board. An exposed
conductor is dangerous because it causes
electric shock.
Mandatory
Cabling must be done by qualified personnel.
The wrong cabling can cause fire, module
trouble or electric shock.
