Proper Use; Designated Power Supply Systems - Eaton RAMO5 Manual

1.7 Proper use

1.7.1 Designated power supply systems

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 per-
sons 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 for use in commercial applications.
RAMO5 and RASP5 are electrical apparatus for controlling vari-
able 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 is intended only for switching, protecting, and con-
trolling 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.
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 a grounded star point and separate N and PE conductors (TN-S net-
work). An ungrounded layout is not allowed.
• All Rapid Link function modules fulfill the safe isolation requirements of.
• The thermistor circuits in RAMO5 and RASP5 units have double basic
insulation.
• All devices 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 grounded on the secondary
side. The 30 V DC PSU for the AS-Interface power supply (Interface con-
trol unit) must meet safe isolation requirements according to SELV.
• Emergency switching off devices (as per IEC/EN 60204-1, corresponding
to DIN VDE 0113, Part 1) must be present. Their function must not be
impaired in any way.
• Effective lightning protection measures must be implemented in the
plant to prevent damage to electronic components.
Connecting the units to IT grounding systems (networks without a reference
to ground potential) is not permitted, since the devices' internal filter capaci-
tors connect the supply system to ground potential (enclosure).
