3．Mounting and Installation
3.1 Handling Precautions
(1) Do not drop or apply heavy impact to the base adapter. Doing so could
result in damage.
(2) Fully secure the MELSEC-Q Series or MELSEC iQ-R Series base unit and
conversion adapter anchor base using the installation screws, and
securely tighten the screws within the specified torque range. Loose
screws could cause a short circuit, fire or malfunction.
Screw Location Tightening Torque
Range
Base unit installation screw (M4 screw) 1.39 to 1.89N･m
Conversion adapter anchor base installation screw (M4 screw)
3.2 Installation Environment
Refer to the manual supplied with the MELSEC-Q Series or MELSEC iQ-R
Series module you use.
