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 pre-
vent damage to the electronics.
• The current type and voltage of the mains connection must correspond to the
specifications on the name plate.
• The electrical connection must be established via a fixed power cable
(3 x 1.5 mm
tor 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 onsite network relay:
nominal current ≥ 10 A, nominal voltage250 VAC
• Fuse protection: 10/16 A, slow-blow or automatic fuse with C characteristic
• Double pumps: provide a separate mains connection cable and a separate
fuse on the mains side for both motors of the double pump.
• A motor protection switch supplied by the customer is not required. Neverthe-
less, 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. Labeling: FI -
When dimensioning the residual-current-operated protection switch, take the
number of pumps connected and their nominal motor currents into account.
• When pumps are used in systems with water temperatures above 90°C, a suit-
able heat-resistant supply cable must be used.
• All connection cables must be installed so that they do not touch the pipe and/
or the pumps or motor housing.
• In order to ensure drip protection and strain relief on the threaded cable con-
nection, cables with a sufficient outer diameter (see Table 7.2) must be used
and 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 accu-
mulated drips. Unused threaded cable connections should be blanked off with
the sealing plates provided, and screwed tight.
DANGER! Risk of fatal electrical shock!
There may be dangerous contact voltage at the contacts of the IF Module
interface.
If no IF Module (accessory) is plugged into the module compartment, the
stopper (Fig. 7, item 1) must cover the IF Module interface so that it cannot
be touched. Make sure that it is seated correctly.
