Safety notices on the use of the device
WARNING
Safety extra low voltage
There is an additional requirement if devices are operated with a redundant power supply:
External power supply
NOTICE
Power supply
The following safety notices must be adhered to when setting up and operating the device
and during all associated work such as installation, connecting up or replacing devices.
The equipment is designed for operation with Safety Extra-Low Voltage (SELV) by a
Limited Power Source (LPS). (This does not apply to 100 V...240 V devices.)
This means that only SELV / LPS complying with IEC 60950-1 / EN 60950-1 / VDE 0805-1
must be connected to the power supply terminals. The power supply unit for the equipment
power supply must comply with NEC Class 2, as described by the National Electrical Code
(r) (ANSI / NFPA 70).
If the equipment is connected to a redundant power supply (two separate power supplies),
both must meet these requirements.
● Use only an external power supply that complies with EN 60950.
● The output voltage of the external power supply must not exceed 30 VDC.
● The output of the external power supply must be short-circuit proof.
The power supply unit to supply the CMR must comply with the requirements for a limited
power source according to IEC/EN 60950-1, section 2.5.
The external power supply for the CMR must meet the requirements for NEC class 2
circuits as specified in the National Electrical Code ® (ANSI/NFPA 70).
Note the information in this section and in the installation and operating instructions from the
manufacturer of the power supply.

Note
Power supply unit of the CMR is not electrically isolated
No electrical isolation means that the input and output circuits are not galvanically is
4.1 Power supply
If power is supplied to the module or station over longer power cables or networks, the
coupling in of strong electromagnetic pulses onto the power supply cables is possible. This
can be caused, for example by lightning strikes or switching of higher loads.
The connector of the external power supply is not protected from strong electromagnetic
pulses. To protect it, an external overvoltage protection module is necessary. The
requirements of EN 61000-4-5, surge immunity tests on power supply lines, are met only
when a suitable protective element is used. A suitable device is, for example, the Dehn
Blitzductor BVT AVD 24, article number 918 422 or a comparable protective element.

NOTICE
Avoidance of sudden disconnection of the power supply
4.1 Power supply
The CMR operates with a DC voltage of 12 to 24 VDC, nominally 24 VDC. The nominal
current consumption is a maximum of 250 mA at 12 V.
● Connect a suitable power supply to the screw terminals.
● Use copper wires only.
Avoid abrupt, uncontrolled disconnection of the CMR from the power supply: There is a risk
of damaging the CMR!
1. Hold down the SET button for 5 to 10 seconds.
2. Disconnect the CMR from the power supply.
The CMR can no longer be woken out of the shutdown status. Power cycling necessary.
The CMR shuts down to the safe status: All LED indicators are off.

4.3 SMA antenna sockets
If you install an antenna outside, you need to ground the antenna to protect it from lightning
strikes. This work must only be carried out by qualified personnel.
Select the antenna suitable for your frequency band from the accessories. Other antennas
could interfere with product characteristics or lead to defects.
The CMR has two antenna sockets of the type SMA for connecting the antennas. The
antennas must have an impedance of approx. 50 Ω.
Follow the operating instructions of the antennas used. See also section Antenna and
cabling technology for LOGO! CMR (Page 137).
Depending on the frequency bands your mobile wireless provider uses:
● Select the antenna suitable for your frequency band from the accessories (Page 137).
During installation make sure that there is a good signal strength:
● If the "R" LED is lit green or flashes green, the signal strength is very good.
● Lit yellow or flashing yellow signals medium quality.
● If the "R" LED is not lit, this indicates an inadequate signal strength, refer also to the
section LEDs to display operation (Page 19).
Large metallic objects in the vicinity of the antennas, for example reinforced concrete, impair
the signal strength.
