Safety instructions for maintenance

Observe Chapter, "Safety instructions" when carrying out any work at the converter.
Improper maintenance and repairs
Improper repairs can result in death and serious physical injury.
Only qualified maintenance and installation personnel may perform repairs.
Danger as a result of defective seals
When working on the device, seals at the doors, roof panels as well as front, rear and side
panels can be damaged. Operating the device 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 specifications.
High voltage when the anti-condensation heating is operational
The anti-condensation heating system is used when the drive is switched off due to production
downtime or maintenance. For this reason, the heating is supplied with voltage from a
separate line supply. When the supply voltage for the anti-condensation heating is connected,
dangerous voltages are present in the cabinet unit, even with EMERGENCY OFF or when
the main switch is open.
This voltage can cause serious injury.
The five safety rules must be observed.
Hot anti-condensation heating surface
When the temperature control limit value is reached the anti-condensation heating is switched
on. Once activated, the anti-condensation heating can generate a great deal of heat. Contact
can result in serious injury, such as skin burns.
Do not touch the anti-condensation heating.
