Maintenance

On the Redundancy box, no special maintenance is required in principle.
The electronic control system itself is built largely maintenance-free. Due to the mechanical stress of the
contactors and relays, these should be checked annually. Whenever possible, malfunctions are displayed
by the display. Defective parts must be replaced by quali ed personnel in compliance with the applicab-
le safety regulations.
CAUTION
All maintenance and inspection work on the Redundancy box may only be carried out by
quali ed and trained personnel in compliance with the statutory safety regulations.
