The power supply can also be used on two-phases of a three-phase-system.
Such a phase-to-phase connection is allowed as long as the supplying
voltage is below 240V+10%. Use a fuse or a circuit breaker to protect the
N input. The N input is internally not protected and is in this case
connected to a hot wire. Appropriate fuses or circuit breakers are specified
in section 22.4 “External Input Protection”.

From a safety standpoint, the unit is internally designed according to the requirements for Protection Class 1 and 2.
Please contact PULS if you do not plan to use the PE terminal. A different marking of the front foil is then required. In
such cases the PE terminal will change to an EMI ground terminal. Be aware that a connection to ground or earth of
this terminal must be done in the same manner as it would be a “real” PE terminal. (wire size, isolation, …)

Connecting this terminal can be beneficial to gain a high EMI immunity.
Symmetrical spikes or fast transients on the input side can be conducted directly to earth by the built-in filter
capacitors. The magnitude of such spikes or fast transients on the output side caused by the input is much smaller
compared to not connecting this terminal to ground.
