Circuit breakers (required)
The circuit breakers must meet the requirements of the printer and should be in accordance with the Electrical
Code requirements of the local jurisdiction of the country where the equipment is installed.
The printer requires one or two branch circuit breakers, depending on the installation.
NOTE:
The printer has built-in Residual-Current Circuit Breakers (RCCB), also known as Ground Fault Circuit
Interrupters (GFCI), with 30 mA sensitivity. If local laws require an external RCCB or GFCI for earth fault protection,
install a device with sensitivity of 100 mA or higher, with appropriate rated current for the supply configuration,
and ensure that other protective devices for earth fault protection upstream from the one supplying the printer
are always greater than the one selected for the printer.
WARNING!
The rated short-circuit breaking capacity of the circuit breakers in the printer is 6 kA. This shall be
coordinated with the branch circuit breaker in PDU (Power Distribution Unit) if so required by the Electrical Code
of the local jurisdiction.
WARNING!
Ensure that the printer's built-in Residual-Current Circuit Breakers (RCCB) or Ground Fault Circuit
Interrupters (GFCI) operate in the case of a current leakage fault to the product chassis, even when an isolation
device (such as an isolating transformer) will be used to supply power to the printer.
Power cables
No power cable is provided with the printer. The cables that you use must meet the minimum specifications for
the chosen configuration explained for each configuration.
PE connections for mains power should be made through an M8 stub.
The power cable for PC power can be routed from above the right of the top cover; it can be routed from the
ceiling.
Powerline disturbances
Reliable operation of your printer depends on the availability of relatively noise-free AC power.

In order to ensure optimum performance and reliability, your printer should be protected from variations in
line voltage, which are common to production printing environments. Lighting, line faults, or the power
switching commonly found in machinery in factory environments can generate line transients that far
