CABLE SECTIONS
It determines ·for B2 installation method· the minimum section of the
cable through which the maximum current allowed in continuous duty
can circulate on three-phase wires in PVC hoses or installed on the
machine through conduits or channels according to UNE-EN 60204-
1:2007. The ambient temperature considered is 40°C/104°F.
JOINING THE CHASSIS BETWEEN MODULES
The chassis of each module must be connected to the machine
ground point. Use the washers and nuts supplied with each module to
make the ground connection. The tightening torque must be between
2.3 and 2.8 N·m. Connecting these terminals by means of metal
plates offers mechanical ridigity; but it does ot guarantee proper
ground connection of each module
.
PROTECTIVE EARTH CONNECTIONS
The chassis of each modules must be connected to a single point
and from there to the ground terminal of the electrical cabinet. When
applying a 10 A current between this ground point and any of these
points, the voltage drop must not exceed 1 V. Use the nuts supplied
with each module to make the ground connection.
When not having a separate ground point, join the plates to the
terminal of the power supply module which, in turn, will be connected
to mains ground
ELECTRICAL DRAWING
The schematics of the following pages are only an orientation to
design the machine and may be expanded or reduced at wil.
The first one shows a set of modular drives powered by a non-
regenerative PS power supply.
The second one is a set of modular drives powered by a regenerative
XPS power supply.
The third one ilustrates the connection of a SERCOS-II interface.
The fourth one shows the connection of a CAN interface.

MANDATORY. The dielectric insulation of the cable must
be enough to withstand the test voltage at a minimum of 2
000 Vac for 5 minutes for cables supporting voltages over
50 Vac (alternating current) or 120 Vdc (direct current).
Refer to the recommendations of the cable manufacturer
before doing the installation.
WARNING. Before handling the power leads: Always
disconnect the three-phase voltage at the electrical
cabinet. Wait, before handling these leads (about 4 min.).
MANDATORY. Take a protective earth cable (as short as
possible) from each module to each main machine ground
point. The cable section must be the same as that of the
cables connected to the largest servomotor (at least 6
mm²).
MANDATORY. It is up to the system integrator to meet all
the requirements of local and national electrical codes as
well as all the regulations applicable regarding the
grounding of the whole unit.
