6. Use and Safety
ATTENTION: Concerning protection against indirect contact (depending on the type of power supply provided
and connection of the exposed conductive parts to the equipotential protection circuit), refer to point 6.3.3 of
EN 60204-1 (IEC 60204-1) with the use of protection devices for automatic shut-off of power in the event of
an insulation fault with a TN or TT, system, or for the IT system, with the use of a permanent insulation or
differentials controller for automatic shut-off. The requirements of IEC 60364-4-41, 413.1 must apply for this
protection.
ATTENTION: Failure to comply with these instructions means the customer runs the risk of machine failure
and/or accidents due to direct or indirect contacts.
5.1 Grounding
Check the efficiency of grounding on the installation itself. The grounding cable must not be with the gas or water
pipes or with telephone cables. Connect the plug and the respective grounding cables in accordance with the
local electrical standards.
5.2 Warnings
Any operation that requires access to the parts under voltage must be done by a qualified ELECTRICAL
TECHNICIAN, and the following procedure must be carried out.
•
Switch of the machine.
•
Disconnect the electricity at the mains switch.
•
Remove the plug from the socket.
•
Carry out the maintenance or repair work.
•
Connect the machine to the mains supply.
ATTENTION!
Connection to the electrical power supply must be done according to proper professional practice by a
qualified and authorized person (see current standards and legislation in the country of installation). If an
adapter is used on the socket, a check must be made that the electrical characteristics of this adapter are not
lower than those of the machine.
Do not use multiple plugs.
The AC power supply to the machine must comply with the following conditions.
- Maximum voltage variation: ±5%
- Maximum frequency variation: ±1% on a continuous basis, ± 2% over short periods
ATTENTION: the electrical installation must comply (for design, creation, and maintenance) with the legal
and standard requirements in the country where used.
Check that the electric mains voltage, the value shown on the specification plate and the label on the power
cable are the same.
- The machine’s electrical power supply must be protected against voltage surges (short-circuits and excess
voltages) by using fuses or thermal relays of the appropriate gauge relative to the place of installation and
machine specifications.
