Electrical Connection - Grundfos JPA Series Installation And Operating Instructions Manual

2.4 Electrical connection

Carry out the electrical connection according to local
regulations.
Check that the supply voltage and frequency
correspond to the values stated on the nameplate
and that it is possible to make a good earth
connection.
Single-phase motors incorporate a thermal switch
and require no additional motor protection.
DANGER
Electric shock
Death or serious personal injury
- Before starting any work on the product,
make sure that the power supply has
been switched off and that it cannot be
accidentally switched on.
DANGER
Electric shock
Death or serious personal injury
- The protective earth of the socket outlet
must be connected to the protective
earth of the pump. The plug must
therefore have the same PE connection
system as that of the socket outlet. If
not, use a suitable adapter.
We recommend that you fit the permanent
installation with a residual-current circuit
breaker (RCCB) with a tripping current
less than 30 mA.
DANGER
Electric shock
Death or serious personal injury
- If the pump is used for cleaning or
maintenance of swimming pools,
garden ponds or similar places, make
sure that the pump is supplied through a
residual-current circuit breaker, RCCB,
with a rated residual operating current
of 30 mA.
DANGER
Electric shock
Death or serious personal injury
- Power supply cables without a plug
must be connected to a supply
disconnecting device incorporated in
the fixed wiring according to the local
wiring rules.
DANGER
