instructions".
9.1 Safety instructions for maintenance
Danger due to improper maintenance and repairs
Improper repairs can result in death and serious physical injury.
● Only qualified maintenance and installation personnel may perform repairs.
Danger due to defective seals
When working on the device, seals at the doors, roof panels as well as front, rear and side
panels can be damaged. Operation with defective seals can result in death, serious injury or
material damage.
● Replace the defective seals before commissioning. Observe the environmental conditions
stated in the technical data.
Danger as a result of high voltages from external supplies
Magnetizing and demagnetizing equipment that is fed from an external voltage source can
result in high voltages. This voltage can result in death or serious injury.
● Ensure that no voltage from external feeds exists before commencing maintenance and
repair work.
Danger due to high voltages at the anti-condensation heating
The anti-condensation heating system is used when the device is switched off during non-
operational periods or when maintenance work is being carried out. For this reason, the heating
is supplied with voltage from a separate line supply. When the power supply voltage for the anti-
condensation heating is connected – also for an EMERGENCY OFF or when the main switch
is open – a hazardous voltage is still present. This voltage can cause serious injury.
● The five safety rules must be observed.
