Important:
• To connect the valve, use a CAREL shielded cable code E2VCABS*00
(AWG22) or an alternative suitably sized 4-wire shielded cable:
- reverse valve or valve size > = E3V45 -> solenoid required with
AWG22 shielded cable
- direct valve and valve size < E3V45 -> if the solenoid is installed
AWG22 shielded cable, if the solenoid is not installed, for the size of
the cables see the table to the side.
• the input of the 0 to 10 Vdc modulating actuator load must have
reinforced insulation, based on its internal power supply.
