NOTE
• The performance level (PL) and safety category in accor-
dance with EN ISO 13849-1 depend on the external wiring,
the application case, the choice of control device and how
this is physically arranged on the machine.
• The user must carry out a risk assessment in accordance
with ISO 14121-1.
• The entire system/machine must undergo validation in
accordance with the applicable standards on the basis of
this.
• The stated performance level will only be achieved if, taking
into account the prevailing device load (see EN ISO 13849-1
Table C.1) and the application case, an average number of
switching cycles per year is not exceeded (see EN ISO
13849-1, C.2.3 and Table K.1). Assuming that the B10d
value is 400,000 for the maximum load, the maximum cycle
number would be 400,000 / 0.1 x 30 = 133,333 switching
cycles per year.
• The safety-related characteristics only apply when the relays
are switched at least once per year.
• Operating the device other than specified can result in
malfunctions or destruction of the device.
• The device must be checked to ensure it is in perfect
working order before commissioning, after replacement of
modules and/or in the case of changes to an installation that
has already undergone acceptance.
• For operation at 115–230 VAC, the operating equipment of
the control circuits must be designed for a rated voltage of
300 V. Basic isolation between supply and control circuits.
• The specified times must always be adhered to when
operating the device; otherwise, the device may become
locked. Locking may be reversed by opening the safety
NOTE
inputs in the proper manner.
• The expansion units of the SNE series or external contactors
with positively-driven contacts can be used for duplicating
the enabling current paths
• The contacts must be fused with maximum 6 A operating
class gG.
• Control outputs S11 and S21 are equipped with overload
protection (for short circuits). Once the cause of the error
has been rectified, the device is ready for operation again
after approx. 3 s.
• The control inputs and outputs are only used for the con-
nection of control devices and not for the connection of
external consumers such as lamps, relays or contactors.
• External loads must be equipped with a suitable protection
circuit for the load (e.g. RC elements, varistors, suppressors,
etc.) in order to reduce electromagnetic interference and
increase the service life of the output switching elements.
• The application-specific standards must be observed when
installing and operating the device.
• The safety functions have not been checked by UL. The
certification process has been carried out in accordance
with the requirements for general applications as stipulated
by UL508.

Mounting Dismantling
1. Attach the device to the DIN
rail.
2. Snap the device on to the
DIN rail by applying slight
pressure in the direction of
the arrow.
3. Press the device down in
the direction of the arrow.
4. While pressed down,
detach the device from the
latching (in the direction
indicated by the arrow) and
remove it from the DIN rail.
