In setting group 0, the maintenance mode setting (register 403006) can be
divided into two parts. The high byte is read only, and is used for the status
indication of the maintenance mode, the comprehensive results of the
maintenance mode rotary switch, the secondary terminal, and the
communication settings. The low byte can be configured and is used to
indicate the maintenance mode settings via the communication port
(e.g. Modbus, CAM or USB).
The respective protection settings may vary according to the size, type and
rated operational current of the release.
