The maximum distance between two pCO
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
• 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.

WARNING
• for applications subject to strong vibrations (1.5 mm pk-pk 10/55 Hz), secure the cables connected to the µ pCO
placed around 3 cm from the connectors
• 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 CAREL service centre;
• in domestic environments, the connection cable between the pCO
