Mitsubishi A1SJ71E71N-B2, E71N-U-HW, A1SJ71E71N-B5T Wiring Precautions, Installation Precautions

[INSTALLATION PRECAUTIONS]

CAUTION

!Install so that the tabs at the bottom of the module fit securely into the base unit mounting holes. (The AnS series module shall be fastened by screws in the base unit at the specified torque.)

Not installing the module correctly could result in erroneous operation, damage, or pieces of the product falling.

!Tighten the screw within the range of specified torque.

If the screws are loose, it may result in fallout, short circuits or malfunction. Tightening the screws to far may cause damage to the screw and/or the module, resulting in fallout, short circuits or malfunction.

!Make sure to switch all phases of the external power supply off before mounting or removing the module.

If you do not switch off the external power supply, it will cause electric shock or damage to the product.

!Do not touch the electronic parts or the module conducting area directly.

It may cause erroneous operation or failure.

[WIRING PRECAUTIONS]

CAUTION

!Perform correct pressure-displacement, crimp-contact or soldering for external wire connections using the tools specified by the manufactures. Incorrect connection may cause short circuits, fire or malfunction.

!Attach connector to the module securely.

!Be sure to fix communication cables or power supply 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, alllowing them to be accidentally pulled, which may cause a module malfunction and cable damage.

!Tighten the screw within the range of specified torque.

If the screws are loose, it may result in short circuits or malfunction.

Tightening the screws to far may cause damage to the screw and/or the module, resulting in fallout, short circuits or malfunction.

!Do not grab on the cable when removing the communication cable connected to the module.

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 part that is connected to the terminal block.

Pulling the cable that is still connected to the module may cause a malfunction or damage to the module or cable.

!Solder coaxial cable connectors properly.

Insufficient soldering may cause malfunction.

!Be sure that cuttings, wire chips, or other foreign matter do not enter the module. Foreign matter may start a fire or cause an accident or erroneous operation.
