14.1 Power supply module (LQV410)

This section explains how to replace the power supply module.
The replacement process involves removing the existing module and installing the new one. For details on these
procedures, see 14.1.1 and 14.1.2 respectively.
● To avoid electric shock, turn off the switch at the AC/DC power source (the MCCB or FFB, for
example) before removing or installing a power supply module.
● To avoid electric shock, do not touch the pins on the power supply input terminal block.
● Take care to tighten the screws securely. Failing to do so can result in the system stopping or
malfunctioning, or cause a module to fall.
● To avoid malfunction, make sure that each module is subjected to a run-in process before installation.
