CAUTION! Risk of damage to property!
An incorrect electrical connection can cause damage to property.
• If the wrong voltage is applied, the motor can be damaged!
• Control via triacs/semi-conductor relays must be checked on a case-by-base basis,
since the electronics can be damaged or the EMC (electromagnetic compatibility)
might be negatively affected.
• When the pump is switched on/off by external control devices, the mains voltage pulsing
(e.g. by a pulse packet control) must be deactivated to prevent damage to the electronics.
• The current type and voltage of the mains connection must correspond to the specifica-
tions on the rating plate.
• The electrical connection must be established via a fixed power cable (3 x 1.5 mm
mum cross-section), equipped with a plug and socket connector or an all-pole switch
with a minimum contact opening width of 3 mm.
• The following minimum requirements are to be met if shutdown takes place by means of
an on-site network relay: Rated current ≥ 10 A, rated voltage 250 VAC
• Fuse protection: 10/16 A, slow-blow or automatic fuse with C characteristic
• A motor protection switch supplied by the customer is not required. Nevertheless, if such
a protection switch is available in the installation, it must be bypassed or set to the highest
possible current.
• Leakage current per pump I
• It is recommended to safeguard the pump with a residual-current-operated protection
switch. Labelling: FI –
When dimensioning the residual-current-operated protection switch, take the number of
pumps connected and their nominal motor currents into account.
• A heat-resistant connecting cable must be used when using the pump in systems with
water temperatures of above 90°C.
• Under no circumstances may any connecting cables touch the pipeline or the pump or
motor housing.
• In order to ensure drip protection, including strain relief, cables with a sufficient outer
diameter (see Table 7.2) must be used and the threaded cable connection must be
screwed sufficiently tightly. In addition, the cables near the screwed connection are to be
bent to form a drainage loop, to drain any accumulated drips.
• Earth the pump/unit according to regulations.
• L, N, : mains connection voltage: 1~230 V
the mains connection between the 2 phases of a three-phase network grounded at the
star point is possible with a delta voltage of 3~230 V
• SSM: An integrated collective fault signal is applied at the SSM terminals as potential-free
normally closed contact. Contact load:
• Minimum permissible: 12 V DC, 10 mA
• Maximum permissible: 250 V AC, 1 A
DANGER! Risk of fatal accident!
Improper connection of the collective fault signal (SSM) contact poses a risk of fatal
injury due to electric shock.
When connecting the collective fault signal (SSM) to the mains potential, the phase to
be connected and phase L1 on the mains connection cable of the pump must be identical.
• Switching frequency:
• On/off switching operations via mains voltage ≤ 100/24 h
• ≤ 20/h for a switching frequency of 1 min. between switching on/off via mains voltage.
