WARNING
The user is responsible for the physical protection of the BUSBARs and other safety devices intended to prevent harm
to persons: For this purpose, the front cover or two side covers provided with the drive must be used (on the two
modules at each side of the system). Connect the power supplies of the DR2020 with a cable terminated with
eyelet "terminals"
4.3.5.5. Auxiliary voltage and signal connection
The 24 V DC auxiliary voltage must be provided from an external source to the +24 V and 0 V terminals on the front panel.
4.3.5.6. Power supply signal connection
The power supply has a CAN connector (X10) that feeds the CAN line of the drives directly; the pinout is the same as the
Axis modules. See paragraph "2.2.2. Connectors and LEDs ". Do not use in case of Ethercat.
4.3.6.
Axis module cabling
Connect the DR2020 to the DM2020 power supply using shielded cables with a cross section that ensures a negligible
voltage drop towards the connected modules (2.5 mm
2
minimum recommended section for power supply and auxiliary
power supply).
4.3.6.1.
Earthing
Connect the module housing to the structure of the board, making sure the contact surface is adequate and the connection
has low resistance and low inductance. Avoid fitting the module housing on painted or insulated surfaces.
FINISH THE NON-INSULATED TERMINAL (5 mm TOWARDS THE INSIDE
OF THE TERMINAL BLOCK) WITH THERMO-SHRINKABLE TUBE OR
INSULATING CAP ACCORDING TO THE FOLLOWING TABLE

4.3.5.4. BUSBAR connection
The +DC bus and -DC bus terminals of the power supply and axis modules must be connected in parallel. In this way, the power from
the power supply and power from regeneration are divided between all axis modules. Only the BUSBARs provided with the drive must
be used for connections.
