5. 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.
• If rigid conduit is to be used, the hub must be connected to the
conduit system before it is connected to the terminal box of the
pump.
• The pump must be connected to an external mains switch.
• The pump requires no external motor protection.
• The motor incorporates thermal protection against slow
overloading and blocking.
• When switched on via the power supply, the pump will start
pumping after approx. 5 seconds.
5.1 Supply voltage
1 x 115 V ± 10 %, 50/60 Hz, PE.
1 x 208-230 V ± 10 %, 50/60 Hz, PE.
See Pump Nameplate for rated supply voltage
The voltage tolerances are intended for mains voltage variations.
They should not be used for running pumps at other voltages than
those stated on the nameplate.
5.2 Connection to the power supply
Warning
Never make any connections in the pump control
box unless the electricity supply has been
switched off for at least 5 minutes.
Warning
The pump must be connected to an external
mains switch with a contact separation of at least
1/8 inch (3 mm) in each pole.
The ground terminal of the pump must be earth
ground. Grounding or neutralization can be used
for protection against indirect contact.
If the pump is connected to an electric
installation where a Ground Fault Circuit
Interrupt (GFCI) is used as additional protection,
this circuit breaker must trip out when ground
fault currents with DC content (pulsating DC)
occur.
Note
Note
The number of starts and stops via the power
supply must not exceed four times per hour.
