Electrical connection

Warning
Electrical connections should be established only in the absence of voltage and
by qualified personnel.
Warning
Use only power units which guarantee reliable electrical isolation of the
operating voltage as per IEC/DIN EN 60204−1. Observe also the general
requirements for PELV power circuits as per IEC/DIN EN 60204−1.
Note
Long signal cables reduce the immunity to interference.
S Make sure that the signal cables are not longer than 20 m.
Connect the earth cable
1. Fit the earth cable ( 2 ) and the two
toothed discs to the functional earth
connection using the enclosed screw
( 1 ) (è Fig. 5).
There must be one toothed disc on
each side of the cable lug.
2. Connect the earth connection with
low impedance (short cable with
large cross−sectional area) to the
earth potential.
You can thereby avoid interference
from electromagnetic sources and
ensure electromagnetic compatibility
in accordance with EMC directives.
