Carry out the electrical connection
according to local regulations.
Check that the supply voltage and
frequency correspond to the values stated
on the nameplate.
DANGER
Electric shock
Death or serious personal injury
- Switch off the power supply before
starting any work on the product. Make
sure that the power supply cannot be
accidentally switched on.
DANGER
Electric shock
Death or serious personal injury
- The pump must be earthed.
- The pump is supplied with a grounding
conductor and grounding-type
attachment plug. To reduce the risk of
electric shock, be certain that the pump
is connected only to a properly
grounded, grounding type receptacle
(protective earthing).
- If national legislation requires a
Residual Current Device (RCD), a
Ground Fault Circuit Interrupter (GFCI),
or equivalent in the electrical
installation, this must be type B
(according to UL/IEC 61800-5-1) or
better, due to the nature of the constant
DC leakage current.
If the power supply cable is damaged, it
must be replaced by the manufacturer, his
service agent or similarly qualified persons
in order to avoid hazard.
We recommend that you fit the permanent
installation with a residual-current circuit
breaker (RCCB) with a tripping current
less than 30 mA.
