Electrical installation
3.4.3
PE conductor components
Connect the PE terminals of all other components, such as mains filters etc.,
in star configu-
ration
to the PE rail (main earth) in the cabinet. See Figure 3.7, p. 30.
Also comply with local and national regulations and conditions.
WARNING!
The chokes have no PE connection. They are intended solely for installation in
a cabinet, as with IP00 protection they offer no protection against direct or
indirect touch contact.
3.5
Electrical isolation method
The control electronics, with its logic (µP), the inputs and outputs, are electrically
isolated from the power section (mains supply/DC link). All control terminals are
designed as safety extra-low voltage/protective extra-low voltage (SELV/PELV) circuits
and must only be operated with voltages from 5 V to 50 V, as per the relevant
specification. This provides reliable protection against electric shock on the control side.
The control electronics therefore need a separate control supply, compliant with the
requirements of a SELV/PELV.
The opposite overview shows the potential supplies for the individual terminals in detail.
This concept also delivers higher operational safety and reliability of the Power Supply
Unit.
SELV = Safety Extra Low Voltage
PELV = Protective Extra Low Voltage
