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
connection 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 HCS01 drive controllers, at least 10 mm
2
, but not smaller than
the cross sections of the outer conductors of the mains supply
feeder.
Additionally, mount the housing 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 con‐
trol cabinet.
Installation
Connect the equipment grounding conductor of the mains or motor cable via
thread M5 to the housing of the device (identification mark
; tightening tor‐
que: 5 Nm). The screws M5×12 required for this purpose are part of the sup‐
plied accessory
.
