EMC-compatible installation
5.3.1
Motor cable
The applicable standard for interference emissions is EN 61000-6-3. Compliance with this standard is
achieved through the use of an unscreened motor feed cable.
5.3.2
Control cables
Pay attention to suf
fi
cient distance from powerlines and motor wires to prevent interferences. The
control cable may not be longer than 30 m. Screened control cables must be used when the cable
length is longer than 20 m. When using a shielded cable connect the shielding to one side only, i.e.
only to the control unit with the protective ground (keep cable short and with as little inductance as
possible!).

Mains connection
5.4.1
Line voltage
Power from the mains is connected to terminals: PE, L1 and N. Here, it must be strictly observed that
the mains voltage lies within the allowable tolerance speci
fi
cations (

xed to the side).
A connection between two phase conductors is possible for 3 ~ 230 V supply networks.
Attention!
To activate the on current limitation, you must wait at least 90 seconds after switching off the line
voltage before switching back on!
5.4.2
Line protection fuse
The mains connection must be fused depending on the used cable, the type of routing, the operating
conditions and according to the standards applicable on site. The speci
fi
cation for the maximum
admissible line fuse of the device must be observed (see technical data).
Possible components for the line protection (recommendation):
•
Safety fuses of operating class
“
gG
”
(whole range fuse cartridges for general applications according
to EN 60269-1).
•
Line protection switch with characteristic
“
C
”
(according to EN 60898-1).
•
Motor protection switch with overload and short-circuit trigger (according to EN 60947-4-1). Setting
overcurrent trigger to maximum permissible current of the line.
