Safety Instructions - IFM Electronic efector 300 VS 0200 Notice D'utilisation

S
AFETY INSTRUCTIONS
F
ollow the operating instructions, as failure to do so may result in
damage to both the unit and persons using the equipment.
E
nsure that the unit is isolated from any supply voltages before
installing or changing the equipment. Installation should only be car-
ried out by qualified personnel (due to the IP20 rating). When altering
the settings of the units please ensure that the unit is not connected to
the monitored plant.
T
he design of the units corresponds to protection class II except for
the terminal blocks where protection against accidental contact
(safety from finger-touch to IP20) for operation by qualified staff is only
guaranteed if the terminal screw has been completely screwed in. This
is why the unit always has to be mounted in a control cabinet of at least
IP54 which can only be opened by means of keys.
I
f the unit has an external 24 V DC supply, this voltage has to be gen-
erated and supplied externally according to the requirements for safe
extra-low voltage (SELV) since without further measures this voltage is
supplied near the operating elements and at the terminals for the sup-
ply of connected pulse pick-ups.
T
he wiring of all signals concerning the SELV circuit of the unit must
also meet the SELV criteria (safe extra-low voltage, safe galvanic
separation from other circuits).
I
f the externally supplied or internally generated SELV voltage has an
external connection to ground (SELV becomes PELV), the responsibility
lies with the user in the framework of the respective applicable nation-
al regulations for installation. All statements in the operating instruc-
tions refer to SELV voltage which is not grounded.
A
ccording to the technical specifications below the unit can be oper-
ated in a wide operating temperature range. Because of the addi-
tional internal heating the operating elements and the housing walls
can have high perceptible temperatures when touched in hot environ-
ments.
I
n case of malfunctioning of the unit or uncertainties please contact the
manufacturer. An unauthorised access of the unit can lead to consid-
erable risks for the safety of persons and plant. It is not permitted and
leads to an exclusion of liability and warranty.
