Proper use
Rapid Link is intended only for switching, protecting and controlling
three-phase motors in machines and installations. Any other or
additional use is considered improper use. The manufacturer or
supplier does not accept liability for damage caused by improper
use.
To ensure proper use of the decentralized power supply systems,
observe the instructions and guidelines for the mechanical and
electrical installation, commissioning and operation.
• Rapid Link must be operated only on 400V-three-phase systems
with earthed star point and separate N and PE conductors (TN-
S network). It must not be operated unearthed.
• All Rapid Link function modules fulfil the safe isolation
requirements of IEC/EN 60947-1, Annex N, between the AS-
Interface
®
voltage and the 24 V
H
and 400 V
h
supplies as
well as to the thermistor circuit in RA-MO and RA-SP-.
• All devices am connected to the power and data bus must also
meet the requirements for safe isolation according to IEC/EN
60947-1 Annex N or IEC/EN 60950. The 24 V DC power supply
unit must be earthed on the secondary side. The 30 V DC PSU
for the AS-Interface
®
power supply (interface control unit head
station) must meet the safe isolation requirements according to
SELV.
• Emergency-Stop devices (according to IEC/EN 60204-1) must
be fitted and their function must not be impaired in any way.
• The plant must contain effective lightning protection measures
to prevent damage to electronic equipment.
Improper use
Engineering
The Rapid Link function modules are installed immediately
adjacent to the drives. They can be connected to the power and
data bus at any point without having to interrupt the bus.
Data bus
The AS-Interface
®
data bus is a system solution for networking
different modules. AS-Interface
®
networks are quick and easy to
implement.
Data cable
AS-Interface
®
uses a geometrically encoded, unscreened flat cable
with a cross-section of 2
x
1.5 mm
2
. It is used to transmit both
power as well as all data traffic between PLC and I/O and – to some
extent – supplies the connected devices with energy. The
installation meets the usual requirements. Engineering is simplified
by full flexibility in system layout and mounting.
When a link is connected to the flat cable, two metal pins pierce
through the cable’s jacket and into the two cores to establish a
contact with the AS-Interface
®
cable. There is no need to cut and
strip cables, apply ferrules or connect individual cores.
Rapid Link function modules can be installed and removed any
number of times in various locations within the system. The
AS-Interface
®
flat cable is self-healing, dust-proof and protected
against spray water. The network can be laid out in a star, linear
or tree structure.

Warning!
Risk of hazard from connected actuators (motors,
hydraulic units, etc.) through incorrect configuration,
installation, maintenance and operation of the complete
plant or machine, non-observation of the instructions in
this manual and handling by insufficiently qualified
personnel.
