3.2 Earthing
Note
• Connect the earth terminal of the MTR-DCI with low im-
pedance (short cable with large cross section) 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
exclusively the following earth terminal:
– Earthing strap on free end of the power supply cable; see
assembly instructions for cable KPWR-MC-1-SUB-9HC-...
Caution
Earth or mass loops can make EMC safety measures inef-
fective and allow high compensating currents to destroy
the motor unit.
• Connect only the cable screening of the power supply
cable to the functional earth FE.
• Do not connect the terminal GND with the housing,
screening, or functional earth FE!
• Never connect one of the power supply connections (see
chapter 3.2, A1, A2) with FE or with the housing.
This will avoid damaging the device and impairing protec-
tion against electromagnetic interference (EMC).
