•
Refer to the wiring diagram, the machine data plate and technical specifications
for service size requirements.
•
Check that the mains voltage corresponds to that indicated on the nameplate.
•
The power-supply cord shall be Type S, SE, SO, SOO, ST, STO, or STOO (with
or without W at the end).
•
The power supply cord wire size must be suitable for the rated current of the
machine (amperage load). Use copper conductors only.
•
The appliance must be grounded using the ground connection of the terminal
block of the appliance.
•
An all phase Circuit Breaker must be installed near to the appliance between the
power supply and the appliance in accordance to required consumption
guidelines. Switch the circuit breaker to “OFF” when servicing the appliance. It is
recommended that it has lockout-tagout capabilities. The manufacturer will not be
held liable for damage originated by failure to observe this requirement.
•
A suitable safety switch / Residual current device must be installed near the
appliance between the power supply and the appliance. The manufacturer will not
be held liable for damage originated by failure to observe this requirement.
•
If any faults are observed during the installation, the supplier should be notified
immediately.
When a number of appliances are installed in line, they should all be ground bonded at the point
provided for that purpose.
To access the connection strip when a permanent connection needs to be made, release the cover of
the machine’s front (see chapter 2. General measurements and connections). The power cable is
connected to the connection strip. It is also possible to change the machine configuration here.
The manufacturer will not be held liable for any personal or material damage to the
machine resulting from incorrect installation or failure to comply with the
manufacturer’s specifications.
It is the personal responsibility and obligation of the customer to contact a
qualified electrician to assure that the electrical installation is adequate.
