If pulsed residual currents occur as a result of transient (short-term) mains overvoltages and uneven
phase loading when starting up, an all-current sensitive residual current circuit breaker in line with
DIN VDE 0160 and EN 50178 must be used.
The circuit breakers must be marked with the two symbols shown. A conventional type A residual
current circuit breaker, also called RCD (residual current-operated protective device) is not permit-
ted.

Note
When selecting the residual current circuit breaker, the total leakage current of all
electrical equipment in the installation must be taken into account.
5.3
Overvoltage protection
The pump is protected against overvoltages by means of varistors installed between the phases
and between the phases and earth.
5.4
Supply voltage
3 × 400 V, +/-10% 50/60 Hz
5.5
Leakage currents
With VivarA, leakage currents (touch currents) of up to 3.5 mA can occur. The pump is protected
against higher leakage currents by a protective earth conductor ex works.

The pump must be safeguarded by the customer and connected to an external mains switch. All
cables used must be heat-resistant up to 85 °C. They must not touch the piping, pump and motor

Ensure that the electrical data specified on the nameplate corresponds to the power supply availa-
ble. The cables must be kept as short as possible, except for the protective conductor cable. This
must be selected so that it is the last conductor to be torn off if the cables are inadvertently torn
out of the gland.
