The I
OUT
output current path supplies the output circuit of
the output modules with power, as well as the I
L
connected
actuators. The current must be refreshed with the UR20-PF-
O (power feed-out), as required. These UR20-PF-O modules
isolate the output current path to the left (towards the cou-
pler), and as a result start a new electricity segment to the
right.
The design of the power supply being used
must take start-up peaks into account.

The power supply is restricted according to the temperature.
The following values apply for the horizontal and vertical po-
sitioning of the u-remote station:
Horizontal Vertical

Temperature-dependent values for the power supply
ATTENTION
Equipment may become damaged if improperly
rated circuit protection is used!
▶ A UL-approved Type-B automatic circuit breaker must be
used.
▶ Use a fuse with a maximum of 10A protection, which is
matched to the rated current (example: fuse rated at
≤5A for a 5A power supply).
