Control panel checklist
NOTICE:
The control panel must be compatible with the
data of the electric pump powered by the same
panel. It is essential to consider the limitations of
use of the control panel together with those of the
electric pump. Inappropriate combinations do not
guarantee the functionality and protection of the
electric pump and control panel.
Check that the following requirements are met:
•
The control panel must protect the pumps
against short circuits. A time lag fuse or a cir-
cuit breaker (Type C model is suggested) can
be used to protect the control panel.
•
A time lag fuse which is inside the control
panel protects the pump against short circuits.
A 12A gG fuse for the pumps is provided (F1,
F2). Refer to Figure 7.
•
The control panel must be programmed cor-
rectly. Refer to the
ming" section (sections 5.4.3, 5.4.4)
Motor checklist
Use a 3-wire power cable (2 + earth/ground). All
cables must be heat-resistant up to a minimum of
+70°C (158 °F).
Mechanical installation
4.2
NOTICE:
•
Incorrect mechanical installation can cause
the control panel to malfunction and break.
•
Read this manual and the manual for the
electric pump before installation.
Ensure that the following conditions are met:
•
Refer to figure
4
for proper mounting of the
control panel.
•
Do not install the control panel in an area ex-
posed to direct sunlight and/or near heat
sources. Refer to the ambient temperature
range in the
•
Technical
data section.
•
Install the control panel and the electric pump
in a dry, frost-free site, observing the limita-
tions of use and ensuring the motor is suffi-
ciently cooled.
•
Do not use the product in explosive atmos-
pheres or in the presence of corrosive
and/or flammable dust, acid, or gas.
Electrical installation
4.3
Precaution
"Start-up and program-
WARNING:
•
Make sure that all connections are
executed by a qualified installer and
in compliance with the regulations
in force.
•
Before running the unit (control
panel and electric pump), make
sure that the unit and the control
panel are isolated from the power
supply and cannot be energised.
Grounding (earthing)
Electrical hazard
•
Always connect the external protec-
tion conductor to the ground (earth)
terminal before making other elec-
trical connections.
NOTICE:
Make sure that there are no bits of wire or
sheathing or other foreign materials in the control
panel when making the electrical connections.
Take all due care to avoid damaging the internal
parts when removing anything inside.
