5 Safety regulations and installation notes
• When working on the device, observe the national safe-
ty and accident prevention regulations.
• Disregarding these safety regulations may result in
death, serious personal injury or damage to equipment.
• Startup, mounting, modifications, and upgrades should
only be carried out by a skilled electrical engineer!
• Disconnect the power to the module.
• For emergency stop applications, the machine must be
prevented from restarting automatically by a higher-lev-
el control system.
• During operation, parts of electrical switching devices
carry hazardous voltages.
• During operation, the protective covers must not be re-
moved from the electric switchgear.
• Keep the product documentation in a safe place.
• The device is associated equipment and may not be in-
stalled in potentially explosive areas. When installing
and operating associated equipment, the applicable
safety directives must be observed.
• Observe the safety regulations that are applicable when
motors are used in the Ex area (ATEX directive 94/9/
EG).
• If you use the "Automatic RESET" mode, the drive is
switched on again after the cooling time has expired - if
a control signal is still present. The cooling time is 20
minutes. For applications in the Ex-protection area, au-
tomatic restart is not permitted.
• The equipment may not be exposed to mechanical or
thermal influences that exceed the limits as described in
the operating instructions. To protect the device against
mechanical or electrical damage, install it in a suitable
housing with appropriate degree of protection accord-
ing to IEC 60529/EN 60529, if required. Where dust is
present, the device must be installed in suitable housing
(IP64, minimum) according to EN 50281.
• Install the device according to the instructions in the in-
stallation instructions. Access to circuits within the de-
vice is not permitted.
• The operating equipment cannot be repaired by the
user and must be replaced by an equivalent device. Re-
pairs may only be carried out by the manufacturer.
• For safety technical data, please refer to this document
and certificates (EC-type examination certificate and
other approvals if appropriate).
• The device executes a function diagnosis when the
drive is switched on or is in the switched on state. In ad-
dition, an authorized electrician or a skilled worker who
is well acquainted with the relevant standards can con-
duct the "Motor overload protection" safety function
test. For this test, the drive must be activated and the
current flow in a conductor interrupted (e.g. by removing
the fuse in the L1 or L3 phase). The hybrid motor starter
then switches off the drive within 1.5 to 2 s. The LED for
right rotation (forward running) goes out, and the Err-
LED and the reply output are set.
• The device must be secured with the help of an access
protection during safety-related applications.
• Only use power supply units with safe isolation and
PELV according to EN50178 / VDE0160 (PELV). This
prevents short circuits between primary and secondary
sides.
• Observe the minimum permissible load current in safe-
ty-related applications:
ELR H3-...ES.../500AC-0,6: ≥ 75mA
ELR H3-...ES.../500AC-2: ≥ 180mA
ELR H3-...ES.../500AC-9: ≥ 1.5A
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). The de-
vice can cause unwanted radio interference if used in
Class B environments (household). In this case, the
user may be obligated to take the necessary precau-
tionary measures.
