7 Connections and wiring
7.1 Required tools
The following tools are required for the electrical installation:
● Flathead screwdriver for supply terminals (blade width 5.5 mm)
● Flathead screwdriver for terminals X2.1 and X2.2 (blade width 3.0 mm)
● Flathead screwdriver for housing screws (blade width 5.5 mm)
● Mounting tools for M20 (width across flats 22 mm) and M32 cable glands
(width across flats 36 mm)
7.2 Power supply
The power supply (supply line) must be hardwired to an existing domestic in-
stallation and comply with the applicable national regulations.
Main switch
The device does not have its own power switch. The circuit breaker of the
supply line serves as a main switch.
7.2.1 Cable installation
Note the following points during cable installation:
● The supply line must be guided far enough into the cable gland that the
cable sheath is visible in the connection area. An appropriate diameter
of cable gland for the cable diameter must be observed in order ensure
leak tightness.
● Make sure that the connection cables are inserted through the opening
centered, straight and without pressure to ensure tightness.
● The installation pipe or cable conduit with the supply line may not be
screwed into or run through the opening.
● The supply line must be routed straight through the opening in compli-
ance with the bending radii (approx. 10x cable diameter).
7.2.2 Connection example
The device is connected using the three phases L1, L2 and L3, the neutral
conductor N and the protective conductor PE.
