5.4 Procedures for Installing Directly (with M4 Screws)
Installation of extension module
1. Make mounting holes on the mounting surface
according to the external dimensions diagram.
2. Push in the DIN rail mounting hook (A in the right figure)
of the extension module. If the DIN rail mounting hook is
not pushed in, the screw hole is covered, and the
extension module cannot be mounted. (This procedure
may not be required, depending on the model.)
3. Fit the extension module (B in the right figure) to the
holes, and secure it with M4 screws (C in the right
figure).
