2.1.1 Function of warnings
Warnings warn users about hazards when handling the product. The hazards are classified,
specified, described and supplemented with information about how to avoid them.
If there is a warning before a list of instructions, the hazard is present throughout the en-
tire activity.
If there is a warning immediately before an instruction, the hazard is present during the
next step.
2.1.2 Design of warnings
All warnings are indicated by a signal word and a warning symbol. The different combinations of
the signal word and warning symbol indicate the degree of danger.
DANGER
For an immediate hazard that will result in severe injuries or death.
WARNING
For an immediate hazard that could result in severe injuries or death.
CAUTION
For a potentially hazardous situation that could result in injuries.
CAUTION
For a potentially harmful situation in which the product or an item near it could be
damaged.
CAUTION
For a hazard that could cause environmental damage.

4 Product description
The SAFEONE DN3PW1 measures the phase voltage at the measurement inputs L1, L2, L3.
If one or 3 phases are missing during the operation, the outputs switch off.
The reaction time and the measurement voltage tolerance are adjustable in the device.
The readiness for operation and the switching status of the contact outputs are displayed
via LEDs.
The device is intended for mounting on a 35mm standard rail.
Phase monitoring can be deselected by wiring input I1.
4.1 Function description
The SAFEONE DN3PW1 measures the phase voltage at the measurement inputs L1, L2, L3
and impresses them. This process is repeated every 60 s.
If the measuring voltage of all three phases is within the tolerance range, the contact outputs
13/14, 23/24 and output O3 switch on after 3s. Otherwise the outputs remain switched off.
As soon as a voltage outside the tolerance limit is measured on one or more phases, the out-
puts switch off after the reaction time.
The outputs remain switched off for at least 1.5s, even if the measuring voltage returns to the
tolerance range within this time. The interruption is indicated by the LED K2. This remains off
and can be switched on again by switching off the operating voltage for 1s or by a falling signal
level at input I1.
4.1.1 Reaction time
The reaction time is adjustable in the device from 10 to 100ms.
