3.2 Earthing
Note
• Connect the earth connection of the MTR-DCI with low
impedance (short cable with large cross-sectional area)
to the earth potential.
This prevents interference from electromagnetic sources
and ensures electromagnetic compatibility in accordance
with EMC directives.
In order to connect the MTR-DCI to the earth potential, use
only the following earth connection:
– Earthing strap on the free end of the power supply cable,
see assembly instructions for cable KPWR-
MC-1-SUB-9HC-... (See chapter 3.3.2)
Caution
Earth or ground loops can make EMC safety measures
ineffective and allow high compensating currents to des-
troy the motor unit.
• Connect only the cable screen of the power supply cable
to the functional earth FE.
• The GND connection must not be made to the housing,
screening or functional earth FE!
• Never connect one of the voltage connections (see
chapter 3.2, A1, A2) to FE or the housing.
This will avoid damaging the device and impairing protec-
tion against electromagnetic interference (EMC).
