Thrust actuator ARI-PREMIO-Plus
5.7.3 Heating
A heating resistor should be fitted as a means of protection against the formation of
condensation water in cases involving widely varying ambient temperatures, high
atmospheric humidity (outdoor use) and temperatures below the freezing point. The heating
resistor is self-regulating so that a continuous supply of current merely needs to be
connected up.
5.7.3.1 Installation of heating
On principle, the heating can be combined with all options. It is completely mounted on a
holding bracket.
To install the heating proceed as follows:
- Switch-off mains voltage and safeguard to prevent it from being switched back on again
accidentally.
- Loosen hexagon screw on the hood, carefully remove hood.
- Using the supplied screws, mount complete heating (on holding bracket) at the point on
the gearbox cover plate provided for the purpose. (Fig. 25).
- Lead continuous-current cable (mains voltage = rated voltage of heating) through cable
inlet into thrust actuator and fix in place with inlet.
- Strip continuous-current cable approx. 1-1,5 cm above cable inlet.
- Strip individual conductors approx. 5mm away from the end and provide with conductor
end sleeves.
- Lay the individual conductors in such a way that they do not come into contact with
moving parts.
- Connect the individual conductors up to the connection terminal block in accordance with
the wiring diagram.
