6 Assembly
6.1 Safety
WARNING!
Risk of Injury due to Unexpected Movement of Components
For vertical or slanted mounting position: when power is off, moving parts can
travel or fall uncontrolled into the lower end position.
• Bring moving parts of the product into a safe end position or secure them
against falling.
6.2 Fasten the central lubrication system supply line
Reducing load on the supply line
Attach the supply line to the lubrication adapter only in combination with a strain
relief
Connect central lubrication system DGC-C, DGC-FA-C, DGCI-C
Restriction of the central lubrication system connections
When using shock absorbers, shock absorber retainers with stops or lateral pro
file mounting the number of permissible connection variants for the central lubric
ation system is reduced.
