Note:
• a maximum of one terminal (pCOT, pCOI, pGD0, pGD1) can be connected, or two terminals but without using
use the backlighting on display. One version of the pCO
network.
• the graphic terminal and aria terminal should be always powered with a separate power supply.
• the 21 Vdc present at +Vterm (J24) can be used to power an external terminal with a maximum input of 2
W. Only one terminal can be connected (for example PLD terminal or ARIA terminal) in addition to the one
connected to terminal J10.

• If the product is installed in industrial environments (application of the EN 61000-6-2 standard) the length of
the output connections must be less than 30 m.
• installation must be performed according to the standards and legislation in force in the country where the
appliance is used;
• for safety reasons the appliance must be housed inside an electrical panel, so that the only accessible part is the
display and the control keypad;
• all the very low voltage connections (analogue and digital inputs at 24 Vac/Vdc, analogue outputs, serial bus
connections, power) must have reinforced or double insulation from the mains;
• in the event of malfunctions do not attempt to repair the appliance, but rather contact the REHAU service
centre;
