4 Installation Electrical connection ✱ Open the case. ➪ Section 3.2 "Opening the case", page 10. ✱ Pass the connection cable (cable diameter 10 — 16,5 mm) through the screw connection (3). Fitting type"X" (no special tools), screw connection up to 2.5 mm conductor cross-section. -
Page 16: Closing The Case
4 Installation 4.2.1 Closing the case ✱ Make sure that the plastic gasket in the lower part of the case ( 2 ) is seated correctly. On thermostats with code -70, the external reset button ( 3 ) must be located precisely on top of the internal reset button ( 4 ) for the microswitch, since this is the only way the reset button ( 3 ) can be operated from the outside. - Page 17 4 Installation ✱ Turn the screw connection ( 1 ) clockwise until the cable inlet is sealed and Cable relief the cable is secured against pulling out. The cable has to be protected against vibration overload by leaving sufficient extra cable length ( 2 ). ✱...
