Precautions for wiring
External power supply connected to the terminal numbers TB35 and TB36 on the
MEMOCON-SC GL Series (2000 Series I/O)-side terminal block becomes unnecessary.
However, that leaving the terminals connected will not cause a problem because the wire is
not connected inside the Conversion Adapter.

Mounting and Installation
5.1
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 Adaptor 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-Q 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-Q 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.

Installation Method
①
Secure the Conversion Adapter Anchor Base to the Base Adapter or control panel using the
Conversion Adapter Anchor Base installation screws (M4
8) provided as an accessory. (Two
end locations)
②
Remove the terminal block attached with the MELSEC-Q Series Module after loosening the
terminal block installation screws (2 places top and bottom).
Secure the Mounting Bracket to the Q Series Module using the Mounting Bracket fixing screws
[M3.5
6 (Conversion Adapter accessory); four upper/lower locations].
③
Mount the Conversion Adapter onto the Mounting Bracket.
④
Secure the Conversion Adapter using the Conversion Adapter installation screws (M3
30; 4
locations).
Precaution
Before tightening the installation screws, check that the Conversion Adapter has been
securely installed on the MELSEC-Q Series Module. Tightening the screws in floating-off state
or tilting state will damage the Conversion Adapter installation screws and the Mounting
Bracket.
⑤
Secure the Conversion Adapter using the Conversion Adapter bottom installation screw (M3
20; 2 location).
⑥
Secure the terminal block of the MEMOCON-SC GL Series (2000 Series I/O) to the Conversion
Adapter with the terminal block installation screws (M3; two upper/lower locations).
