7.2 Electrical connection

DANGER! Risk of fatal injury!
Improper electrical connections pose a risk of fatal injury due to electric
shock.
• Only allow the electrical connection to be made by an electrician approved
by the local power supply company and in accordance with the local regula-
tions in force.
• Before working on the pump, all poles of the power supply must be discon-
nected. Work on the module may only be started once 5 minutes have
passed, due to the dangerous residual contact voltage.
• Check to ensure that all connections (including potential-free contacts) are
voltage-free.
• If the control module is damaged, the pump must not be put into operation.
• If setting and operating elements are improperly removed, there is a danger
of electric shock if interior electrical components are touched.
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.
• 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.
