3.8 Electrical installation
Carry out the electrical connection and protection according to
local regulations.
Check that the supply voltage and frequency correspond to the
values stated on the nameplate.
Make sure that the pump is connected to an external main
switch.
The pump requires no external motor protection.
The motor incorporates thermal protection against slow
overloading and blocking (IEC 34-11: TP 211).
When switched on via the power supply, the pump starts after
approximately 5 seconds.
3.8.1 Supply voltage
1 x 230 V ± 10 %, 50/60 Hz, PE.
The voltage tolerances are intended for mains-voltage variations.
Do not use the voltage tolerances for running pumps at other
voltages than those stated on the nameplate.
Do not insulate the control box or cover the control
panel.

WARNING
Electric shock
Death or serious personal injury
- Before starting any work on the product, make
sure that the power supply has been switched off.
Lock the main switch in position 0. Type and
requirements as specified in EN 60204-1, 5.3.2.
WARNING
Electric shock
Death or serious personal injury
- Connect the pump to an external main switch
with a minimum contact gap of 3 mm in all poles.
- Use earthing or neutralisation for protection
against indirect contact.
- If the pump is connected to an electric
installation where an electrical circuit breaker
(voltage sensing ELCB, residual-current device
RCD or residual-current circuit device RCCB) is
used as an additional protection, this circuit
breaker must be marked with the first or both of
the symbols shown below:
