7.2.1 Single phase mains connection 1~230 V (L, N, PE)
Power supply connection:
• Terminals L, N and PE
Connect the phase connection to terminal L and the protective
earth conductor to terminal PE of the terminal block (Fig. 4).
To provide the timer with 230 V of electricity, connect the neu-
tral conductor to N on the terminal block (Fig. 4).
Pump connection:
• Terminals 2, N and PE
The pump is connected directly to terminal 2 of the time switch
and N, PE on the terminal block (Fig. 4).
7.2.2 Two-phase mains connection 3~230 V (L1, L2, PE) /
(L2, L3, PE) / (L3, L1, PE) for AC pumps, 230 V
CAUTION! Risk of damage to property!
An incorrect electrical connection can cause damage to
property.
• If the wrong voltage is applied, the motor or switchgear can
be damaged!
• This connection to two phases is only permissible for these
switchboxes and for AC pumps when the delta voltage in the
supply system is 230 V.
Power supply connection:
• Terminals L, N and PE
When the delta voltage in the system is 230 V
Connect the connection of one of the phases L1, L2 or L3 to the
terminal L and one of the other phases L1, L2 or L3 to terminal
N of the terminal block. PE is connected to the terminal PE of
the terminal block (Fig.4).
Pump connection:
• Terminals 2, N and PE
The pump is connected directly to terminal 2 of the time switch
and N, PE on the terminal block (Fig. 4).
