Ryobi 754P. Machine was turned on after a month. Fault showing 002 error. Battery was on 0 volts too.

Hello everyone. I need some help. The printing press was turned off for a whole month. Upon powering it on, none of the indicator lights on the sections lit up. The battery—which measured 0 volts—was replaced, but this was done while the press was powered off. The client reports that a new error has appeared since the battery replacement: 002. Power is reaching the main contactor for the inverter, but the contactor fails to engage, preventing the inverter (and thus the motor) from starting. It is possible that the system is preventing the startup. Could this be due to the battery—i.e., has all the data been lost?
