A
Mains connection
The length of the mains supply cable is not limited. However, it
must be installed separate from the control, data and motor
cables.
B
DC-link connection
The frequency inverters are to be connected to the same mains
potential or a common direct voltage source. Cables longer than
300 mm are to be shielded. The shield must be connected to the
mounting panel on both sides.
C
Control connection
Keep control and signal cables physically separate from the
power cables. Analog signal lines are to be connected to the
shield potential on one side. Install sensor cables separate from
motor cables.
D
Motor and braking resistor
The shield of the motor cable is to be connected to ground
potential properly on both sides. On the motor side use a metal
compression gland. On the frequency inverter side an
appropriate shield clamp is to be used. The signal cable used for
monitoring the motor temperature must be kept separate from
the motor cable. Connect the shield of this line on both sides. If
a braking resistor is used, the connection cable must also be
shielded, and the shield is to be connected to earth potential on
both sides.
Relay
The relay enables using high-energy signals.
Line choke
Line chokes reduce mains harmonics and reactive power. In addition, a longer service life of the
frequency inverter is possible. When using a line choke, note that line chokes may reduce the
maximum output voltage of the frequency inverter.
The line choke must be installed between the mains connection and the input filter.
Input filter
Input filters reduce grid-bound, high-frequency radio interference voltage.
Install the input filter on the mains side upstream of the frequency inverter.
CAUTION
The frequency inverters meet the requirements of the low-voltage directive
2006/95/EC and the requirements of the EMC directive 2004/108/EC. The EMC
product standard EN 61800-3 relates to the drive system. The documentation
provides information on how the applicable standards can be complied if the
frequency inverter is a component of the drive system. The declaration of conformity
is to be issued by the supplier of the drive system.
