Safety Instructions

Only trained professional electricians may install,
startup, modify, and retrofit this equipment!
Disconnect the device/system from all power
sources prior to starting any work! If installation
or system errors occur, line voltage may be
present at the control circuit in devices without
DC isolation!
Observe all electrical safety regulations issued by
the appropriate technical authorities or the trade
association. The safety function can be lost if the
device is not used for the intended purpose.
Opening the housing or any other manipulation
will void the warranty.
Caution!
If the device has been subjected to improper or
incorrect use it must no longer be used, and the
guarantee loses its validity. Impermissible
conditions include:
strong mechanical stress, for example through
a fall, or voltages, currents, temperatures or hu-
midity outside of the specifications.
Before starting up your machine/plant for the first
time, please be sure to check all the safety func-
tions according to valid regulations, and observe
the specified test cycles for safety equipment.
Caution!
Perform the following precautionary steps prior to
installation, assembly, or disassembly:
1. Disconnect supply voltage to the equip-
ment/system prior to starting any work!
2. Lockout/tag the equipment/system to
prevent accidental activation!
3. Confirm that no voltage is present!
4. Ground the phases and short to ground!
5. Protect against adjacent live components
using guards and barriers!
6. The devices must be installed in a cabinet
with a protection class of at least IP 54.
Caution!
Limited contact protection! Protection type
according to EN 60529.
Housing/terminals: IP 40 / IP 20.
Finger-proof acc. to EN 50274.

Device and Function Description
MSI-SR-CM43
The supply voltage for the unit is lead by one of the output enabling current paths of the basic unit
connected to it. After the supply voltage is applied, the relays K1 and K2 switch into their operating
position. After this switch - on phase the four safety output contacts 13/14, 23/24, 33/34, 43/44
(MSI-SR-CM43) or 17/18, 27/28, 37/38, 47/48 (MSI-SR-CM43DT03) close and the feedback contact
Y1/Y2 opens. The status of relays K1 and K2 is indicated by two LEDs. If the E-Stop button is pressed
the enabling current paths of the basic unit open and the relays K1 and K2 of the MSI-SR-CM43
are de-energized. The safety output contacts open and the feedback contact closes. The feedback
contact Y1/Y2 prevents the re-activation of the basic unit in case the relay K1 or K2 should not be
de-energized.
MSI-SR-CM43DT03
The function corresponds to the one of the MSI-SR-CM43. The MSI-SR-CM43DT03 is supplied with a
fixed OFF-delay time t of 3 s. The item has a time back-up, so that in case of failure of the external
R1
power supply the internal relays K1 and K2 stay energized until the OFF-delay time t
Upon timing-out the relays K1 and K2 go back into their off-position. The OFF-delay times > 0 s
correspond to Stop Category 1.
Proper Use
The device is only to be used as an expansion device for safety switching devices.
Notes
• The MSI-SR-CM43 device's desired stop category and Performance Level (PL) in accordance with
EN ISO 13849-1 or SILCL in accordance with BS EN 62061 always depends on the relevant data
for the basic device (e.g. can the expansion device achieve the Performance Level (PL) of the
base device as a maximum).
• As a safety switching device in stand-alone operation, it corresponds to Performance Level (PL) d
respectively Category 3 according to EN ISO 13849-1 and SILCL 2 acc. EN 62061
• The expansion units can be connected to one or two safety contacts of the basic unit according to
the safety level requested.
• The unit can be combined with all basic safety switching devices. The feedback circuit Y1/Y2 has
to be connected to the RESET or to the feedback circuit of the basic unit.
• External fuse protection for the relay and the contacts should not exceed 6 A type gG.
• If sensors with reed contacts or semiconductor outputs used pay attention to the peak current
(see technical data section control circuits).
• The safety functions are not evaluated by UL. The approval is accomplished according to UL 508,
general use applications.
Please observe instructions from safety authorities.
