1.7 Proper use
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 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).

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.
