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, remove carefully 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.
