Connection of Equipment Grounding Conductor

WARNING
WARNING
Installation
and Controls
High housing voltage and high leakage current! Danger to life, risk of
injury by electric shock!
● Before switching on and before commissioning, ground or connect the
components of the electric drive and control system to the equipment
grounding conductor at the grounding points.
● Connect the equipment grounding conductor of the components of the
electric drive and control system permanently to the main power supply at
all times. The leakage current is greater than 3.5 mA.
● Establish an equipment grounding connection with a copper wire of a
cross section of at least 10 mm
equipment grounding conductor of the same cross section as the original
equipment grounding conductor.
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!
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 HCS01 drive controllers, at least 10 mm
the cross sections of the outer conductors of the mains supply feed‐
er.
Additionally, mount the housing to a bare metal mounting plate.
Connect the mounting plate, too, with at least the same cross sec‐
tion to the equipment grounding conductor system in the control
cabinet.
Connect the equipment grounding conductor of the mains or motor cable via
thread M5 to the housing of the device (identification mark
M5×12 required for this purpose are part of the supplied accessory HAS09.
