Power Supply - RACOM RipEX User Manual

Installation

6.6. Power supply

We do not recommend switching on the RipEX's power supply before connecting the antenna and
other devices. Connecting the RTU and other devices to RipEX while powered increases the likelihood
of damage due to the discharge of difference in electric potentials.
RipEX may be
10 to 30 VDC power source. The supply must be capable
of providing the required input for the projected RF output.
The power supply must be sufficiently stable so that
voltage doesn't drop when switching from receiving to
transmission, which takes less than 1.5 ms. To avoid radio
channel interference, the power supply must meet all
relevant EMC standards. Never install a power supply
close to the antenna. Maximal supply cable length is 3 m.
Warning – hazardous locations
The unit must be powered with an intrinsic save power source for use in hazardous locations.
