  • Page 5 • If there is a danger of a serious accident resulting from a failure or a defect in this unit, provide the unit with an appropriate external protective circuit to prevent an accident. • The unit is normally supplied without a power switch and fuses. Make wiring so that the fuse is placed between the main power supply switch and this controller.
  • Page 6 Caution 2.1 Cautions on installation Avoid the following places for installation. • a place where the ambient temperature may reach beyond the range of from 0 to 50°C while in operation. • a place where the ambient humidity may reach beyond the range of from 45 to 85% RH while in operation.
  • Page 7 Standard : Vertical mounting, flush on the panel. (The controller is horizontal.) When mounting the controller on tilted surface, the maximum tilt angle is 30° (degree) from virtical. (Caution) • Don’t block the openings around the controller, or radiation effect will be re- duced.
  • Page 8 • If inductive load such as magnetic switches connected as a relay output load, it is recommended to use Z-Trap manufactured by Fuji Electric to protect a contact from switching serge and keep a longer life. Model : ENC241D-05A (power supply voltage: 100 V) ENC471D-05A (power supply voltage: 200 V) Where to install : Connect it between contacts of the relay control output.
