3.1 Mounting

The mounting of the switch is done by two col- lars, which are supplied together with the switch, as shown in Fig. 4. The cable gland is directed downwards in any case. The switching point is situated nearby the middle of the box. The heat protection is optional for high temperature appli- cations and is situated between the switch box and the mounting bracket.

3.2 Electrical connections

3.2.1 Power switch

In AC applications the function is comparable to a mechanically operating switch and can be used in con- junction with load relays, gate switches, solenoid valves etc. Because of the wiring (fig. 1) of the solid state switch (Triac) a small permanent current will pass through C1 (47nF).

3.2.2 Miniswitch

For this type of operation, the PHÖNIX type 740.0060 level switch is used as a normal mechanical (REED) switch for low AC/DC-currents. The usual safety precautions for Reed switch contacts must be observed (s. fig. 6b).
