2. Safety regulations / Installation notes

• When working on the device, observe the national
safety and accident prevention regulations.
• Ignoring the safety regulations can lead to death,
serious injury or cause damage!
• The device may only be started up, assembled,
modified or retrofitted by an authorized
electrician!
• Before starting work, disconnect the device from
the power supply!
• For devices with 230 V AC control, make sure that
the same phase is used for the control supply
voltage as well as the control inputs!
• In emergency stop applications, a higher level
control unit must ensure that the machine cannot
start up again automatically!
• During operation, parts of the electric switchgear
carry high voltages!
• During operation, the protective covers must not
be removed from the electric switchgear!
• Keep the operating instructions!
• The device is associated equipment and may not
be installed in potentially explosive areas. Please
comply with the valid safety regulations for the in-
stallation and operation of associated equipment.
• The safety regulations applicable when motors
are used in the Ex area must be complied with
(ATEX directive 94/9/EC).
• If the "automatic RESET" operating mode is used,
the drive is switched on again after the cooling
time is complete as long as a control signal is pre-
sent. The cooling time is 20 minutes. An automa-
tic restart is not allowed in applications in the Ex-
protection area.
• The equipment may not be exposed to mechani-
cal or thermal influences that exceed the limits as
described in the operating instructions. To protect
against mechanical or electrical damage, the
equipment should, if necessary, be installed in an
adequate housing with a suitable degree of
protection (e.g. IP54) in acc. with IEC 60529/
EN 60529. Where dusts are present, the device
must be installed in a suitable housing (at least
IP64) in acc. with EN 61241.

• Installation must be carried out in accordance with
the instructions as described in the operating ins-
tructions. Access to the circuits within the device
is prohibited during operation.
• The equipment cannot be repaired by the user
and must be replaced by an equivalent. Repairs
can only be carried out by the manufacturer.
• The safety relevant data and features as indicated
in the EC type-examination certificate are listed
here following the technical data.
• The device carries out a diagnostics of the
functions when the drive is being switched on or
when it is switched off. In addition, an (electrically)
skilled person or a skilled worker who is well
acquainted with the relevant standards can
conduct the "Motor overload protection" safety
function test. For this test, the drive must be
operated with right or left rotation, thus
interrupting the current flow in a conductor (e.g. by
removing the fuse in the L1 or L3 phase). The
hybrid motor starter with reversing function then
switches off the drive within 1.5...2 s. The LEDs
for right or left rotation extinguish and the Err-LED
and the reply output are set.
• If the connecting cable for remote reset is longer
than 3 m in 230 V AC devices
(ELR W3-230AC/...), it must be shielded.
• The device must be secured with the help of an
access protection in safety-related applications.
• Only use power supply units with safe isolation
and PELV in accordance with EN 50178/VDE
0160 (PELV). This prevents short circuits be-
tween primary and secondary sides.
Area of application:
• In circuits in potentially dust-explosive areas of
zones 21 and 22, it must be guaranteed that the
equipment connected to this circuit complies with
category 2D or 3D or is certified as such.
• This is a product for environment A (industry). In
environment B (household), this device can
cause undesired wireless problems; in such a
case, the user may be under obligation to
implement appropriate measures.
