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 STEADYPRES is in operation; before you
disconnect the pumps, stop the control and disconnect the power supply.
-

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.
