Should the pump be connected to a standard wall socket, it must be checked
that a building protection rated 16 A is installed (fuse or breaker) to protect the
power cable. Even if the pump is not operating, live voltage is present in the
connection box ! Voltage and frequency mentioned on the pump nameplate
must agree with the supply voltage. The control cable must be at least distant
by 10 cm to the mains cable and crossings shall be at 90°. The power socket
and cord are disconnection elements which must remain accessible to the
users.
The motor integrates a motor over-load protection device (red knob on motor
connection box) to be manually reset after an overload trip.
Frequency converter
Should the pump be connected to a standard wall socket, it must be checked
that a building protection rated 16 A is installed (fuse or breaker) to protect the
power cable. The frequency converter itself is self-protecting. Voltage and
frequency mentioned on the pump nameplate must agree with the supply
voltage. Even if the pump is not operating, live voltage is present in the
frequency converter ! The control cable must be at least distant by 10 cm to the
mains cable and crossings shall be at 90°. The power socket and cord are
disconnection elements which must remain accessible to the users.
The pump is protected against over-currents by two 5X20 mm internal fuses
rated 250 V, 12.5 A Time lag T. The fuse is mounted in a separate housing and
can be exchanged from outside using a screwdriver to open the fuse holder
cap. See drawing below.
Exchange fuse only with electrically unplugged pump.
