Before tightening the installation screws, check that the Conversion Adapter has been
securely installed on the MELSEC-L Series module. Tightening the screws in floating-off
state or tilting state will damage the Conversion Adapter installation screws and the
mounting bracket.
Install the MELSEC-L Series system to the base adapter (DIN rail portion) or the DIN rail.
Secure the MELSEC-AnS Series terminal block to the Conversion Adapter with the supplied
MELSEC-AnS Series terminal block installation screw (M4). (2 places, top and bottom.)
Remove the terminal block cover from the MELSEC-AnS Series terminal block and fit the
terminal block cover supplied with the Conversion Adaptor in place.

Mounting and Installation
4.1 Handling Precautions
(1) Before attempting to install the Unit or carry out the necessary wiring, make certain that the
external power supply, used in the system, is shut off on all three phases. Failure to do so may
result in electric shock or damage to the product.
(2) Do not touch live terminals. There is a danger of electric shock or malfunction.
(3) Do not modify the Conversion Adapter or take it apart. Doing so will cause failure, malfunction,
personal injury, or fire.
(4) Do not touch the energized part of the Conversion Adapter directly. Contact will cause
malfunction or failure in the system.
(5) Fasten the Conversion Adapter and the Mounting bracket securely with retaining screws, and
tighten the screws by applying torque within specified limits. Loose screws can lead to the
dropping of the Conversion Adapter, or Mounting bracket, possibly causing breakage thereof.
Excessive tightness of the screws can lead to breakage of the screws, Converter Adaptor,
Mounting bracket, or MELSEC-L Series Module, possibly causing the dropping, shorting, and
malfunction thereof.
(6) Use care to prevent foreign materials including cuttings and wiring debris from entering the
Conversion Adapter or the MELSEC-L Series Module. These will be cause for fire, failure or
malfunction.
(7) Do not drop the Conversion Adapter and Mounting Bracket or do not give a strong impact to it.
This will cause damage.
4.2 Use Precautions

Width dimension
of module
Because the module is reduced in width dimension (34.5mm
→
28.5mm) and
thus in area available for wiring, check dimensional data before installing the
module.
