Wiring Precautions - Mitsubishi Electric AJ65BT-RPI-10A User Manual

[Wiring Precautions]

● Be sure to shut off all phases of the external power supply used by the
system before installation or wiring.
Not doing so can cause the product to be damaged or malfunction.
● Always ground the FG terminal to the protective ground conductor.
Otherwise there will be an electric shock or misoperation.
● Terminal screws which are not to be used must be tightened always.
Otherwise there will be a danger of short circuit against the bare solderless
terminals.
● Use applicable solderless terminals and tighten them with the specified
torque. If any solderless spade terminal is used, it may be disconnected
when the terminal screw comes loose, resulting in failure.
● Perform correct wiring for the module according to the product's rated
voltage and terminal arrangement. Connecting to a power supply different
from the rating or mis-wiring may cause fire and/or trouble.
● Fix terminal screws securely with the specified torque.
Loose terminal screws may cause short circuit or malfunction.
If the terminal screws are too tight, it may cause falling, short circuit or
erroneous operation due to damage of the screws or module.
● Make sure foreign objects do not get inside the module, such as dirt and wire
chips.
It may cause fire, trouble or malfunction.
● Be sure to fix wires or cables that are connected to the module in place,
either by running them through a duct or by using clamps.
If the cables are not fixed in one of these ways, dispersion, movement, or
careless pulling of the cables may cause damage to the module or cables, or
malfunction due to cable contact faults.
● 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.
● When disconnecting a communication or power supply cable from the
module, do not pull on the cable itself.
Before disconnecting the cable from the terminal block, loosen off the screws
of the terminal block.
If you pull the cable connected to the module, the module or cable can be
damaged or misoperation can occur due to cable connection fault.
