SAFETY STANDARDS
Safety important instructions.
This symbol warns that failure to comply with the prescription leads to a risk of electric
shocks.
This symbol warns that failure to comply with the prescription leads to a risk of injury/damage
to persons/objects.
Before installation and use of the product:
-
read this manual completely and thoroughly
-
Check that the
nameplate data
are those desired and appropriate to the system, and in particular that
the
rated current of the motor
is compatible with the
rated current of the inverter
-
Installation and maintenance must be carried out by qualified staff, responsible for performing the
hydraulic and electric connections according to the applicable Standards in force
-
The manufacturer declines all responsibility for damage deriving from improper use of the product and
is not liable for damage caused by maintenance or repairs that are carried out by unqualified staff
and/or using non-original spare parts
-
The use of non-original spare parts, tampering or improper use, make the product warranty null and
void.
During first installation or when carrying out maintenance make sure that:
-
the electric power supply network is not live
-
The power supply network is equipped with protections and in particular of
high-sensitivity
differential switch
(30 mA in class A for domestic application, class B for industrial applications) and
grounding comply with the
Standards.
-
Before removing the inverter cover
or starting interventions on it, the system must be disconnected
from the mains electricity and you must wait for 5 mins until the intermediate circuit condensers, have
the time to discharge via the built-in discharge resistors.
-
do not disconnect the pumps if DGFIT is in operation; before you disconnect the pumps, stop
the control and disconnect the power supply.
-
WARNING: out of service (flashing red LED) DGFIT remains in tension; prior to any work on the
pump or inverter is required, cut off power from the group.
Emergency stop
An emergency stop can be performed while the inverter is running, by pressing the START/STOP key.
In parallel inverters installations, only the MASTER inverter stops the whole system.
PRELIMINARY CHECKS
to ACCESS THE DRIVE WIRING
, open the front cover as shown on p. 5
DO NOT OPEN INVERTER COVERS
, except for the connector cover
DGFIT has not the power switch; the inverter supply line must be protected in
accordance with the regulations
-
Install the inverter in a place:
o
protected from the elements
o
ventilated, free from excessive humidity or excessive dust
o
leave a space for ventilation and cover opening, as shown in the section
"DIMENSIONS"
o
vertical, as close as possible to the pump
o
make sure that does not receive harmful vibrations or mechanical stress from
connected pipelines
-
in case of
long cables
between Inverter and pump motor, evaluate the application of inverter
output sinusoidal filter. It aids smooth running of motors eliminating negative effect of voltage
peaks
