Maintenance
9.1 Safety instructions for maintenance
Observe the general safety instructions for all work on the drive.
Improper maintenance and repairs
Improper maintenance and repairs can result in death and serious physical injury. Only
qualified maintenance and installation personnel may perform repairs.
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 data.
High voltages from external supplies
Magnetizing and demagnetizing equipment that is fed from an external voltage source can
cause high voltages on the drive. This voltage can result in death or serious injury.
Ensure that no voltage from external feeds exists before commencing maintenance and repair
work.
High voltage when anti-condensating 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. The dangerous voltages are even present
with EMERGENCY OFF or when the main switch is open.
This voltage can cause serious injury.
Observe the five safety rules. (Page 23)
