For every connection via a cable it is
strongly recommended that a Wurth Elektronik
no.742 712 11 ferrite be fitted with a double loop.
The connected circuit in RS485 must not exit the
building in which the Smart Dosing device device
is installed (the circuit is not considered TRT1)
**Group 1 definition
Devices of group 1: group 1 combines all the devices that
are not classed as being in the group 2 devices.
Devices of group 2: group 2 combines all the radioelectric
frequency ISM (industrial, scientific and medical) devices
in which radioelectric frequency energy in the 9 kHz to
400 GHz frequency range is produced and used intentio-
nally or only used in the form of electromagnetic radiation,
inductive and/or conductive coupling for the purposes of
examination or analysis or for the treatment of matter.
*Class A definition
The class A devices are the devices intended for use in all
establishments other than residential premises and other
than those connected directly to a low voltage electricity
distribution network supplying residential buildings. The
class A devices must comply with the class A limits.
Warning: The class A devices are intended to be used
in an industrial environment. In the user documentation
an indication must be included drawing attention to the
fact that there may be potential difficulties in ensuring
electromagnetic compatibility in other environments due to
conducted and radiated disturbances.
USB socket
The USB outlet is accessible from the outside by
opening the cover marked with the USB symbol.
The female USB (type A) outlet works only with
a USB stick for the transfer of data/ /firmware
updating as described in the paragraph "USB

RECOMMENDATIONS

- When the DOSATRON SMART DOSING
SD25AL5 system is connected, either to the
public water supply or to its own water point,
it is imperative that back-flow protection and
disconnection standards are complied with.
DOSATRON recommends a disconnector using
a back-flow preventor to avoid contamination
of the water supply.
- When connecting the system to the water supply,
ensure that the water flows in the direction of the
arrows indicated on the water meter AND the
hydraulic doser.
- All electrical connections must be done by
qualified personnel in compliance with local
regulations.
- Install the SD system in a by-pass with shutoff
valves and non-return valves downstream of the
system.
- Ensure that the connection to the system's
electrical supply is protected against water
projections.
- In installations where a siphoning risk exists, it
is recommended that an anti-siphon valve is fitted
downstream of the system.
- Use a chemical container with a lid to limit fumes
of aggressive or hazardous products in order to
secure equipment located above and to protect
personnel.
- Keep the DOSATRON SD25AL5 system away
from significant heat sources and protect it from
freezing in winter.
- Do not install the DOSATRON SD25AL5 system
on the motor pump suction circuit (siphoning).
- To ensure the accuracy of dosing, the annual
replacement of the seals in the dosing assembly
remains the user's sole responsibility. (Dosing seal
preventive maintenance alarm)
