ATTENTION!
In order to avoid accidents, it is mandatory to connect the neutral wire with the neutral of the
electrical network. Also, the ground wire for all types of voltage, according to current
regulations.
Never connect the ground wire to the neutral wire of the mains, water pipes, gas pipes, etc.
For a correct grounding, consider the instructions of standard NBR 5410
– ABNT.
Also included with the equipment is an equipotential grounding terminal (post), located on the
lower rear base of the structure.
The terminal identified in the figure aside is an additional protection to the
grounding that is provided for in the electrical network, it must be connected
to a grounding terminals, regardless of the connection to the electrical
network, and the other products that have accessible metallic parts, and that are stationary,
must also be connected to this bus as well as the service bench itself, if it is made of metallic
material. In this way, all these products will be under the same electrical potential, avoiding
undesirable leakage currents
.
The equipment described in this manual are single voltage, 220 V or 380 V. If you need to
change the voltage of your equipment, please contact the manufacturer or authorized dealer.
ATTENTION!
Before turning on your equipment, always check that the mains supply voltage is the same as
the equipment's voltage. If it is not the same and it is necessary to change the voltage of your
equipment, contact the manufacturer or authorized dealer.
The supply voltage of the equipment is 220 V or 380 V three-phase, as can be seen on the
voltage label affixed to the power cable or as indicated on the nameplate data label located on
the back of the equipment (see figure of this label in item 2.2 of this manual).
Make sure that the voltage of the electrical network where the equipment will be installed is
compatible with the voltage indicated on these labels.
