The protection class plug on slot A ensures
the protective grounding of the hand-held nu-
trunner (see Fig. 3).
The plug position may not be
changed! Otherwise this affects
the electrical safety.
5.7 Fuses
The servo amplifier's intermediate circuit is
protected by two fuses. Should the fuses
blow, the BTB LED changes from green to
red. The system is not operable in this condi-
tion. The fuses are located on the back of the
servo amplifier and must be exchanged in the
case described above. (For removal, please
see Fig. 4).
Caution: The safety instructions in
Chapter 3 (see page 11) must be
observed!
