Wiring the power inputs
The
six
-
contact terminal block connector on the top panel of
industrial
PoE+ switch
is used for two DC redundant
power
inputs. F
ollow
the steps below to insert the power wire.
Caution:
When performing procedures like inserting the wires
or tightening the wire-
clamp screws, ensure that
the power is
OFF to prevent
electrical shock.
1.
Insert positive
and negative DC power wires into contacts
1 and 2 for Power 1 or 5, and 6 for Power 2.
2. Tighten the wire-
clamp screws for preventing the
