3. For the Electrician
All electrical components (sensors, etc.) on the terminal blocks (screwless spring-type terminals) should be
connected with fine-wire PVC sheathed cables and be fixed at the rear with strain reliefs – Fig. 46, 47.
Two separate cables are required for connecting the boiler to the suction turbine or changeover unit – this is a
requirement of the guarantee conditions!
Recommended accessories: Ribbon cable FIRE 042 or FIRE 043; 5 x 2.5 mm

and 8 x 1 mm

Guide the ribbon cable through the rectangular openings and secure with cable ties as strain relief – Fig. 48.
