Riello RS 300/EV BLU Installation, Use And Maintenance Instructions page 17

Mechanical structure
– The control box manages up to 4 adjustment components
based on a command variable, according to freely program-
mable curves.
– The control box has 4 three-point control outputs.
– The control box has 3 three-point control outputs and one 4-
20 mA output.
– The control box has a Sub-D 25-pole connector with serial in-
terface for the remote control and display via PC (Windows
software provided separately).
– Connections for Interbus-S, Profibus-DP CANopen, TCP/IP
(Modbus TCP) and Modbus available as an optional.
– Other BUS systems on request.
– The connection of other system components, e.g.. Fault alert
system, O adjustment, takes place via LAMTEC Bus system
interface with a Sub-D 9 pole connector.
– The control box continuously monitors its operations and
those of the adjustment components connected.

Installation notes
– Check the electric wiring inside the boiler complies with the
national and local safety regulations.
– Phase and neutral must not be swapped.
– Make certain that strain relief of the connected cables is in
compliance with the relevant standards (e.g. as per DIN EN
60730 and DIN EN 60335).
– Ensure that spliced wires cannot get into contact with neigh-
bouring terminals. Use adequate ferrules.
– Arrange the HV ignition cables separately, as far as possible
from the control box and the other cables.
– The burner manufacturer must protect unused AC 230V ter-
minals with dummy plugs (refer to sections Suppliers of other
accessory items).
– When wiring the unit, make sure that AC 230V mains voltage
cables are run strictly separate from extra low-voltage cables
to avoid risks of electrical shock hazard.
