Fagor DDS Series Hardware Manual page 271

INFORMATION. Remember that FAGOR provides all the cables needed for
i
the installation. If the user chooses to make his own cable, - see chapter
CABLES - that indicates the pinout of the connectors at both ends, mechanical
characteristics and other considerations.
 Adjust the modules through the RS-232 serial line using the application
for PC (WinDDSSetup).
INFORMATION. In order for the FAGOR DDS system to meet the European
Directive on Electromagnetic Compatibility 2014/30/EU, the modules
i
installation rules must be strictly followed regarding:
Installation of the mains filter ·MAIN FILTER·.
Electrical installation of the power stage: wiring to mains and motor-drive
power connection.
Electrical precautions
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 10 mm² (Cu) or
16 mm² (Al) or two protection ground wires with the same cross section as
that of the wires connected to the power supply terminals. Comply with local
regulations on grounding. Note the symbol indicating this precaution .
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.
Once the installation is completed and before doing anything with the DDS
system:
WARNING.
Always disconnect all power supplies, including the external power that feeds
the control board that could be present..
Wait at least 4 minutes ·DISCHARGE TIME > 4 min· until the capacitors of
the DC bus are fully discharged. This precaution is indicated on the cover of
the DC bus.
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, HIGH VOLTAGE ·.
Install and close all covers and ground the DDS system before applying
voltage.
Turn off the mains voltage using an appropriate switch to achieve a voltage-
free condition.
MANDATORY. The cross section of the protective ground conductor must
comply with the applicable standards. Ground the cable shields at both ends;
however, the shields are not protective ground conductors.
