3.4 Pump specifications

Refer to the user and maintenance manual of the
electric pump. It is essential to consider the limita-
tions of use of the converter together with those of
the electric pump. See Technical
is responsible for checking the limitations of the
electric pump if they are not specified in this manual.

WARNING:
• Observe accident prevention regula-
tions in force.
• Use suitable equipment and protec-
tion.
• Always refer to the local and/or na-
tional regulations, legislation, and co-
des in force regarding the selection of
the installation site, plumbing, and
power connections.

4.1 Electrical requirements

• The local regulations in force overrule specified
requirements listed below.
Electrical connection checklist
Check that the following requirements are met:
• The electrical leads are protected from high tem-
perature, vibrations, and collisions.
• The current type and voltage of mains connec-
tion must correspond to the specifications on the
data plate on the pump.
• It is suggested to supply power to the converter
with a dedicated power line and it is provided
with:
• A high-sensitivity differential switch (30 mA)
[residual current device RCD] suitable for
earth fault currents with pulsating content. In-
terrupter must be marked with the following
symbol:
ELCB
(GFCI)
Refer to Figure 11
andFigure 12 for models MMA, MTA.
• A mains isolator switch with a contact gap of
at least 3 mm
The electrical control panel checklist
NOTICE:
The electrical panel must be compatible with the da-
ta of the electric pump powered by the converter. In-
appropriate combinations do not guarantee the pro-
tection of the unit.
Check that the following requirements are met:
• The control panel must protect the converter and
the pump against short circuit. A time lag fuse or
a circuit breaker (Type C model is suggested)
can be used to protect the pump.
• The converter must be programmed correctly to
protect the pump from overloading. Refer to
Start-up and programming
• A time lag fuse which is inside the converter pro-
tects the pump against short circuits. Refer to
Figure 12 and Figure 14
The motor checklist
Use cable according to rules with 3 leads (2 + earth/
ground) or 4 leads (3 + earth/ground). All cable must
be heat-resistant up to a minimum of +85°C (185°F).
