Safety Instructions!
Before beginning installation work
 Disconnect the device from the power supply
 Ensure against accidental restart
 Verify isolation from the supply
 Cover or close off neighbouring units that are live.
 The assembly instructions provided for the device are to be
complied with
 Only suitably qualified personnel according to EN 50 110-1/-2
(VDE 0105 part 100) are authorised to carry out work on this
device/system.
 When conducting installation work ensure that you are free of
electrostatic charge before touching the device.
 Connection and signal cables are to be installed so that any
inductive or capacitive interference does not impair the
automation functions.
 The installation of automation devices and their operating
elements is to be carried out in such a way as to prevent
unintentional operation.
 In order to prevent cable or wire breakage on the signal side
generating undefined states in the automation devices,
appropriate safety measures are to be taken for the I/O coupling
on the hardware and software side.
 The functional earth (FE) must be connected to the protective
earth (PE) or the equipotential bonding. The system installer is
responsible for establishing this connection.
 Ensure a reliable isolation of the extra-low voltage for the 24 volt
supply. Only those power supply units that comply with IEC 60
364-4-41, i.e. HD 384.4.41 S2 (VDE 0100 part 410) are to be
deployed.
 Fluctuations or deviations of the mains voltage from the nominal
value should not exceed the tolerance limits specified in the
technical data, otherwise malfunctions and dangerous states
may occur.
