Electrical installation

WARNING
 The configurable safety controller MSI 400 conforms to EMC-
regulations according to EN 61000-6-2 for the industrial
environment.
 The cabinet respectively the installation housing for the
configurable safety controller MSI 400 must have a protection
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 MSI 400, 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.
 The wiring (e.g. for the reset) has to be passed in a screened
and sheathed cable.
 All switching elements connected to the system MSI 400 and 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
elements, such as varistors or RC-elements. The use of these
protective elements can prolong the reaction time of the system
depending on the type of element.
 The safety outputs of the system and the external device
monitoring (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.
