Instructions for Use
Apart from the indicated connections, it is necessary to wire the Bb
contact at the
control section for signaling the readiness for opera-
tion of the drive controller (see
Project Planning Manual "Rexroth

Important Notes
-
!£iiJ;h@[c-
Lethal electric shock by live parts with more
than
50 V!
Exclusively operate the device
• with plugged on connectors (even if there haven't been any lines connec-
ted to the connectors) and
• with connected equipment grounding conductor!
Notes
on
Installation Dimension the required cross section of the connection cables according to the
determined phase current
ILN
and the mains fuse.

Equipment grounding conductor: Material and cross section
For the equipment grounding conductor, use the same metal (e.g.
copper) as for the outer conductors.
For the connections from the equipment grounding conductor con-
nection
of
the device to the equipment grounding conductor system
in
the control cabinet, make sure the cross sections of the lines are
sufficient.
Cross sections of the equipment grounding connections:
• For HCS03.1 E drive controllers, HMV01 and HMV02 supply
units at least
10 mm
2
(AWG 8), but not smaller than the cross
sections
of
the outer conductors of the mains supply feeder
• For HCS02.1 E drive controllers,
at
least 4 mm
2
(AWG 1 0), but
not
smaller than the cross sections of the outer conductors of
the mains supply feeder
Additionally, mount the housing of
HCS02.1 E to a bare metal
mounting plate. Connect the mounting plate, too, with at least
the same cross section to the equipment grounding conductor
system
in
the control cabinet.
For outer conductors with a cross section greater than 16 mm
2
,
you
can reduce the cross section
of
the equipment grounding connec-
tion accordi
ng
to the table "Equipment Grounding Conductor Cross
Section".
