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

. 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
21.3 “External Input Protection”.
21.9. USE WITHOUT PE ON THE INPUT
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.
Grounding of the input is beneficial for 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.
