ELECTRICAL CONNECTIONS
Disconnect the electrical supply before any operations and ensure that the DXA Unit
cannot be started accidentally.
Only cables provided by Aereco must be used to carry on the DXA Unit installation. If using
different cables, Aereco won’t be able to guarantee the good functioning of the appliance.
The installation must be carried out by a professional
in compliance with applicable
regulations in force in the country of installation. Each product or component used in the
installation must also comply with standards in force in the country.
ModBus components (2I2O module or
smart interface) may be connected on
one of the 2 RJ45 ModBus socket (the one
you want, it doesn't matter) for a parallel
wiring. But the ModBus components may
also be connected one after the other for a
serial wiring, up to you.
Each modbus line must be ended with a
ModBus cap. So, 2 ModBus caps must be
connected on the ModBus network (because 2
RJ45 ModBus sockets on the main electronic
board).
