Device version with 100V to 240V AC power supply
In the case of the device version with 100V to 240V AC power supply, the internal
AC/DC voltage converter, the power supply or both modules are to be replaced.
Before removal, it must be checked whether the error is related to the internal
AC/DC voltage converter or the power supply.
In the case of this device version, the replacement of the power supply can only be
performed after the housing side wall facing the power supply (together with the
internal AC/DC voltage converter) has been disassembled.
