External power supply
Use only an external power supply which also complies with EN60950. The output
voltage of the external power supply must not exceed 30V DC. The output of the
external power supply must be short-circuit proof.
Warning
!
The power supply unit to supply the SINAUT MD741-1 must comply with the
requirements for a Limited Power Source according to IEC/EN 60950-1
The power supply unit to supply the SINAUT MD741-1 must comply with NEC Class 2
circuits as outlined in the National Electrical Code ® (ANSI/NFPA 70) only.
Please pay regard to section 2.7 of the system manual, as well as the installation
and utilisation regulations of the respective manufacturers of the power supply, the
battery or the accumulator.
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 2.7 of this system 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.
