Safety precautions
General: The product SINAUT MD740-1 complies with European standard EN60950, 05.2003,
Safety of Information Technology Equipment.
Read the installation instructions carefully before using the device.
Keep the device away from children, especially small children.
The device must not be installed or operated outdoors or at damp locations.
Do not operate the device if the connecting leads or the device itself are damaged.
External power supply: Use only an external power supply which complies with IEC/EN60950
chapter 2.5 "Limited power sources" and UL1310 / NEC Class 2 respectively. The output voltage of
the external power supply must not exceed 30VDC. The output of the external power supply must
be short-circuit proof.
Warning
The power supply unit to supply the SINAUT MD740-1 must comply with NEC Class 2 circuits as
outlined in the National Electrical Code (ANSI/NFPA 70) only
When connecting to a battery or accumulator, make sure that an all-pole circuit-breaker (main
battery switch) with sufficient selectivity and a fuse with sufficient selectivity are provided between
the device and the battery or accumulator.
Please pay regard to section Technical Data of the installation manual, as well as the installation
and utilisation regulations of the respective manufacturers of the power supply, the battery or the
accumulator.
Digital gate input: Make sure that the specified input voltage range is observed. Please pay regard
to sections Connecting the device and Technical Data of this documentation.
Digital gate output: Switching voltage and switching current must not exceed the specified
maximum values. Please pay regard to sections Connecting the device and Technical Data of this
documentation.
SIM card: To install the SIM card the device must be opened. Before opening the device,
disconnect it from the supply voltage. Static charges can damage the device when it is open.
Discharge the electric static of your body before opening the device. To do so, touch an earthed
surface, e.g. the metal casing of the switch cabinet. Please pay regard to section Inserting or
changing the SIM card of the installation manual.
Handling cables: Never pull a cable connector out of a socket by its cable, but pull on the
connector itself. Cable connectors with screw fasteners (D-Sub) must always be screwed on tightly.
Do not lay the cable over sharp corners and edges without edge protection. If necessary, provide
sufficient strain relief for the cables.
For safety reasons, make sure that the bending radius of the cables is observed.
Failure to observe the bending radius of the antenna cable results in the deterioration of the
system's transmission and reception properties. The minimum bending radius static must not fall
below 5 times the cable diameter and dynamic below 15 times the cable diameter.
Radio device: Never use the device in places where the operation of radio devices is prohibited.
The device contains a radio transmitter which could in certain circumstances impair the functionality
of electronic medical devices such as hearing aids or pacemakers. You can obtain advice from your
physician or the manufacturer of such devices. To prevent data carriers from being demagnetised,
do not keep disks, credit cards or other magnetic data carriers near the device.
