2.3 Replace AnS/QnAS (Small Type) Series with L Series
2.3 Replace AnS/QnAS (Small Type) Series with L Series
2.3.1 Replace using A (Small Type) upgrade tool
(manufactured by Mitsubishi Electric Engineering Co., Ltd.)
Solution and Benefit
The existing wiring can be used by using the conversion adapter of the upgrade tool
(manufactured by Mitsubishi Electric Engineering Co., Ltd.) for replacing MELSEC-AnS Series with
MELSEC-L Series. It is unnecessary to drill additional holes, and the man-hour for replacement can
be reduced.
■ Conversion adapter
There are available two types of conversion adapters, one for using the existing AnS module
terminal block without making changes to the wiring and the other for type conversion for connector
type input/output modul
■ Space module
If the wires of the existing terminal block are thick and interfere with the adjacent module, the
conversion adapter to be used may not be mounted. In this case, the wiring space can be secured
to eliminate the interference by installing the space module LG69 on the left of the newly mounted
module.

When the space module LG69 is used, the number of modules per block is restricted. For details,
refer to "Transition from MELSEC-AnS/QnAS (Small Type) Series to L Series Handbook
(Fundamentals)."
■ Base adapter
The base adapter integrated with DIN rail is used to mount the L Series base unit using the existing
mounting holes for the AnS/QnAS Series base unit.
When the base adapter is used, it is unnecessary to fit the DIN rail, and the man-hour for
replacement can be reduced.
