DANGER
Lethal electric shock caused by live parts with more than 50 V!
Connect the drive controller to the equipment grounding system of the control
cabinet.
Supplying device with connection for joint bar:
●
Via the joint bar on the front connect the drive controller to the supplying
device.
Supplying device without connection for joint bar:
●
Via a separate connection line, connect the drive controller to the equip‐
ment grounding system of the control cabinet.
Via the joint bar on the front connect the drive controller to the neighboring drive
controller.
Connect the equipment grounding conductor connection of the supplying de‐
vice to the equipment grounding conductor system of the control cabinet.
Check the continuity of the equipment grounding conductors from the mains
connection to the connected motors.
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 HCS03.1E drive controllers and HMV01 supply units, at
least 10 mm 2 , but not smaller than the cross sections of the
outer conductors of the mains supply feeder
● for HCS02.1E drive controllers, at least 4 mm 2 , but not smaller
than the cross sections of the outer conductors of the mains
supply feeder
Additionally, mount the housing of HCS02.1E 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 mm², you
can reduce the cross section of the equipment grounding connec‐
tion according to the table "Cross section of equipment grounding
conductor, excerpt from EN 61800-5-1:2003".
