WARNING WARNING installation.
The configurable safety controller samos®PRO COMPACT con-
forms to EMC-regulations according to EN 61000-6-2:2001 for the
industrial environment.
The cabinet respectively the installation housing for the configura-
ble safety controller samos®PRO COMPACT must have a protec-
tion degree of IP 54 or more.
Installation according to EN 50274
Electrical installation according to EN 60204-1
To guarantee the EMC the DIN-rail has to be connected to the
functional earth.
All modules of configurable safety controller samos®PRO COM-
PACT, the external EMC-protection and all power supplies have to
be connected to the same ground potential (GND).
The external voltage supply of the modules has to bridgeover a
short voltage drop of 20 ms according to EN 60204.
The voltage supply has to meet the regulations for safety extra low
voltage (SELV, PELV) according to EN 60664 and DIN 50178.
UL 508: The modules must be supplied by an isolated voltage
source with a maximum secondary voltage of 42.4 VDC and fused
such that the maximum power cannot exceed 100 VA. The fuse
shall be either UL listed or recognized in accordance with UL 248.
All supply inputs shall be connected to the same source.
The wiring (e.g. for the reset) has to be passed in a screened and
sheathed cable.
All switching elements connected to the system samos
all PLC next in line and the wiring have to be implemented in
accordance with the required safety categories or safety levels.
For protection of the safety outputs and in order to increase the
working life of contacts external loads must have protective ele-
ments, such as varistors or RC-elements. The use of these protec-
tive elements can prolong the reaction time of the system depend-
ing on the type of element.
The safety outputs of the system and the external device monitor-
ing (EDM) have to be connected and wired within one cabinet.
When changing a controller module it has to be assured that the
memory plug is connected to the designated controller module,
e.g. by wiring or marking.

configurable safety controller samos®PRO COMPACT is docu-
mented in the system manuals "samos
