1.7.1 Designated power supply systems
Observe the following instructions in this manual regarding mechanical and
electrical layout, and commissioning and operation:
• The system must be connected to a three-phase power supply system
with an earthed star point and separate N and PE conductors (TN-S
grounding system). Unearthed configurations are not permissible.
• All Rapid Link function modules comply with safe isolation
between the AS-Interface voltage and the voltages 24 V  and 400/
480 V  as stipulated in IEC/EN 60947-1, Appendix N.
• The thermistor circuits in RAMO5 and RASP5 units have double insula-
tion.
• 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 power supply unit for the AS-Interface® power supply
(head-end controller, interface control unit) must meet safe isolation
requirements in line with SELV.
• Emergency switching off devices (to IEC/EN 60204-1) must be present.
Their function must not be limited in any way.
• Effective lightning protection measures must be implemented in the
plant to prevent damage to electronic components.
The units must not be connected to IT grounding systems (networks without
a ground potential reference) because the devices’ internal filter capacitors
connect the supply system to ground potential (enclosure).

DANGER
Incorrect engineering, installation, maintenance or operation of
the entire plant or machine, non-observation of the instructions
in this manual and modifications by insufficiently qualified
persons can cause danger from connected actuators such as
motors, hydraulic units etc.
￫
RAMO5 and RASP5 are not devices for household use and are
designed exclusively as components for use in commercial
applications. RAMO5 and RASP5 are pieces of electrical appara-
tus for controlling variable speed drives with three-phase
motors. They are designed for installation in machines or for use
in combination with other components within a machine or
system.
￫
Rapid Link 5 is intended only for switching, protecting, and cont-
rolling three-phase motors in machines and plants. Any other
use is not proper use. The vendor does not accept liability for
damage resulting from use other than the stated proper use.
