6.8.2 Installing ground connection or equipotential bonding
WARNING
Electric shock due to faulty ground connection or equipotential bonding.
Severe or fatal injuries.
• Make sure to install the ground connection and equipotential bonding correctly.
You have to protect all electrical operating resources, such as the device or the motor,
using ground connection or equipotential bonding.
Required material
• Short low-impedance HF-compatible cables with M5 crimp cable lug
• Grounding kit (included in the delivery):
– 2 pan head screws, 5 × 14 (self-tapping)
– 4 serrated lock washers
– 2 terminal clips
Tools required
Screwdriver with TX25
Leakage currents
Leakage currents ≥ AC 3.5 mA/DC 10 mA may occur during normal operation. To
avoid dangerous shock currents in accordance with EN 61800-5-1, strictly observe the
following:
• The protective earth (PE) connection must meet the requirements for systems with
high earth-leakage currents.
• Note that the required cable cross section of the PE conductor depends on the
cable cross section of the supply cable. Select the cable cross section of the PE
conductor according to the following requirements:
– Supply cable < 10 mm²: Install two PE conductors with a cable cross section
corresponding to the supply cable. Both PE have to be connected to different
connection points and routed in parallel. Alternatively, use a copper PE con-
ductor with a cable cross section of 10 mm².
– Supply cable 10 mm² – 16 mm
2
: Route a copper PE conductor with a cable
cross section corresponding to the supply cable.
