E 2 V valve output
type 1 for stepper motor, 4 wires, 450 mA max (terminals SH, 4, 2, 3, 1)
protection male/female plug-in connectors, 5 mm pitch
terminal block min. 0.5 mm
cable cross-section the special CAREL cables/connectors can be used, code E2VCAB****
Note:
• Use the SHIELD terminal to connect the shield and the earth (Fig. 4.b).
• Pass the cable to the E 2 V valve inside an MSFC ferrite cable shield (code. CAREL 0907858AXX), near the connector on the MasterCase2
(Fig 4.b)
• For the correct connection of the valve, the cable and the ferrite cable shield, see Fig. 4.b.
• Maximum length of the cable: 6 m.

E2VCON* not suitable for refrigeration application
pLAN network / user terminal connection
type RS-485 asynchronous half duplex
terminal connector 6 pin telephone jack
pLAN connector 3 pin plug-in connector, pitch 3.81 mm
cable special CAREL connection cables can be used, code S90CONN00*
Note:
• The maximum distance allowed varies depending on whether the terminal used has the power supply taken from the control device or
supplied externally, or alternatively if two controllers are connected in a pLAN local network:
- maximum terminal distance with telephone cable and power supply taken from the device: 30 m;
- maximum distance for communication without shielded cable on pLAN connector: 30 m;
- maximum terminal distance with AWG24 shielded cable and power supply taken from the device: 200 m;
- maximum terminal distance with AWG20/22 shielded cable and separate power supply: 500 m;
- maximum distance between two devices with AWG20/22 shielded cable: 500 m;
• A maximum of one terminal (PCOT, I, PGD0, PGD1), or two terminals without using the backlighting on the display, is allowed;
• If using a telephone cable for the creation of a pLAN local network (Master-Slave confi guration), use the branch connector code
TCONN6J000 to avoid damaging the boards due to the presence of the power supply for connecting the terminal.
