The power supply can also be used on two-phases of a three-phase-system. 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 not internally protected and is in this case connected to a hot wire. 
Appropriate fuses or circuit breakers are specified in section 23.4.

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.
