LEASE REFER TO THE ELECTRICAL DIAGRAM AND TO THE USING MANUAL
.
-
The installer must supply the required equipment for the connections (cable, cable channels, cable glands, copper
terminals for main switch …)
-
The installer must check that the main power supply protection is correctly adapted to :
-
Neutral mode
-
Short circuit current of the installation ICC3
-
The main power supply connection is defined for copper cables.
-
Unless otherwise stated, the main power supply cable arrival must be done from the bottom of the control panel (for the
cable entrance in the enclosure) and must be connected above the main switch.
-
If main supply terminals are present, the main supply cable will have to be connected at the lower part of it.
-
If the main supply cable arrival is done at the top of the control panel, the installer will install the necessary cable glands.
-
Warning: The neutral position is normally located on the left of the main switch (blue wire)
-
On page OP10 of the electrical diagram, information such as Voltage level, Short circuit current, neutral mode is available.
-
The main supply cable size, defined by the installer, must take into account the maximum current, the simultaneous
working equipments, the line protection, the length, the voltage dropout, the tracking mode of the cables …
-
In case of neutral mode = Earth Neutral Common, a copper part connecting PE and N will allow to separate those signals for
measurements if needed.
-
The earth connection needs to be connected to the earth terminal or copper bar mounted for this in the control panel.
-
In standard, control panels are planned to be connected with copper cables only.
-
Any work at the electrical equipment must be done by having previously powered OFF the
main supply or the main supplies, by authorized people.
-
The control panels are delivered with their protecting devices against direct contacts,
generally mounted on site (on the main switch, repartitors, copper bars…) or supplied in the
enclosure. The installer must mount back those devices after its work and before to start
the machine.
