General
engineering notes The relevant regulations for safety and prevention of
accidents must be observed. Machines and systems
which are fetted with the PS416 are subject to the
relevant EN-, IEC-, VDE regulations.
Emergency OFF devices acc. EN 60204/IEC 204
(VDE 0113) must always be active in all operation
modes of the controller. A deactiviation of the
emergency OFF device must not cause an
uncontrolled or undefinded restart.
Power supply
When using 24 V power supplies, a safe electrical
isolation of the low voltage must be ensured. Only
power supply units designed acc. IEC 364-4-41 or
VDE 0100 Part 410 may be used.
An isolation monitoring device must be implemented
(IEC 364-4-41 or VDE 0100 Part 410) when using an
unearthed power supply.
With a potentially isolated operation the 24-V-DC
power supply must be a protective low voltage acc.
IEC 364-4-41 or VDE 0100 Part 410 or equivalent.
Suppression of interference sources
Connected inductive loads must always be
protected with suppressor circuits. When connecting
loads, the manufacturers specifications must be
adhered to.
