Diagrams with grounding on a vertex are not
permitted.
MANDATORY.
Only qualified personnel who know and understand the
contents of this manual and all the other documentation
related to this product and have been properly trained on
this safety subject to recognize and prevent existing
risks, are authorized to work with this QUERCUS system.
Only qualified personnel may install, set up, repair and
maintain this equipment.
MANDATORY.
The installation must be fully compliant with all the
requirements of the local and national electrical
regulations and all other applicable regulations.
MANDATORY.
As for possible high leak currents (3.5 mA AC or 10 mA
DC), use a protection ground wire with a cross section of
at least S/2, where S (mm²) is the cross section of the
conductor wires connected to the power supply terminals.
Comply with local regulations on grounding.
WARNING.
The system must always be installed before applying
voltage according to the EN 60204-1 standard. Ignoring it
may cause serious injuries, even death.
WARNING.
Always disconnect all power supplies, including the
external power that feeds the control board that could
be present.
Wait at least 10 minutes · MAX DISCHARGE TIME:
10 min · until the capacitors of the DC bus are fully
discharged. This precaution is indicated on the cover
of the DC bus.
There is no assurance that there is no voltage in the
DC bus when the D7 indicator light is turned off.
Accordingly, never handle the DC bus even when the
D7 led is turned off.
Make sure that the DC BUS voltage is lower than 60
V DC. This precaution is indicated on the front of the
equipment near the cover of the DC bus with the
legend · DANGER, RISK OF ELECTRIC SHOCK ·.
Assemble and close all covers and connect the
QUERCUS system to the ground before supplying
voltage.
Eliminate the mains voltage using an appropriate
switch to obtain a condition without voltage.
MANDATORY.
T h e g r o u n d i n g c a b l e s h o u l d c o m p l y w i t h t h e
corresponding (applicable) standards. Always connect
the ground to the cable shields at both ends, knowing that
the shields are not protection ground conductors.
MANDATORY.
The electrical installation my comply with standard EN
60204-1.

MANDATORY.
The EMC directive defines equipment as any device or
fixed installation. This device is identified as a fixed
installation and is meant to work inside an electrical
cabinet according to category C3 and meeting the EN
61800-3 standard.
* note)
MANDATORY.
The installation that includes this product may need a
harmonic suppressing filter to comply with the EN 61800-
3 standard which is harmonized with the EMC Directive.
Otherwise, when applying solutions to limit the harmonics
in each QUERCUS system included in the installation
could be an expensive solution and/or would not make any
technical sense. It is better to apply a global solution.
