6.2 Motor protection
The motor incorporates thermal overload protection
and requires no additional motor protection.
6.3 Connection of motor
The motor incorporates a starter device and can
therefore be connected directly to the mains.
Start/stop of the pump will typically be done via a
pressure switch. See fig. Connection of motor.
The pressure switch must be rated for the
maximum amps of the specific pump size.
