Notes on fitting and installation
Warning
Before carrying out assembly, installation and
maintenance work, always switch off the voltage
supplies.
Warning
If an axis is fitted in a sloping or vertical position, the
work load may slide down.
S Check whether external safety measures are necess
ary (e.g. toothed latches or moveable bolts).
You can then avoid the work load sliding down if there
is a sudden power failure.
The tolerances for the power supplies must be observed
directly at the connection:
Power supply
Load supply ( 4 , pins A1, A2)
Nominal current / peak current
Internal fuse
Logic supply ( 4 , pins 1, 2)
Nominal current / peak current
Internal fuse
Only with SFC−DC−...−IO:
I/O supply ( 3 , pins 1, 8)
Nominal current / peak current
