8 - ELECTRICAL CONNECTION
In this case, it´s posible to install the TCO terminal on the electrical cabinet.
It’s necessary that the terminal uses the same power supply that the
control board.
Up to four RS485 ambient sensors can be connected in series on the
fi eld-bus of the control board.
8.5 Electric panel
All units include a fully wired electrical panel, with forced
ventilation.
The access door is insulated to prevent condensation. This door
has quarter-turn latches.
Note:
all models have a plug of 230 Vac in the main electric
panel.
These latches of stainless steel have triangular
insert 8 mm (supplied wrench). The closing is
done by rotating 90º (anti-clockwise): it brings
the latch to the locked position.
