Power connection
This unit provides a 6 pin terminal block. PoE functions can be operated from 48-56VDC
power input. Always make sure your input voltage is within this supported voltage range
for each model.
WARNING – Any exceeded input voltage will not make this unit function and may
damage this unit.
This unit comes with 3 power input sources. P1, P2, and P3.
To connect power
: Follow the printed polarity for P1+, P1-, P2+, P2-, and ground. Connect
positive wires to P1+ and/or P2+, connect negative wires to P1- and/or P2-, and connect the
neutral wire to the ground screw as shown.
Power DIN
: This unit contains an extra P3 port for power DIN. This power DIN can power
the unit via external power adapter.
Relay
: This unit includes an additional 24V@1A relay circuit for special purpose. When 2
powers are connected, the relay is in OPEN mode. If only one of the power sources is
connected, the relay changes to SHORT mode. This relay will only work with P1 and P2. It is
independent from P3.
Power connecting procedure:
STEP 1 – Pull out 6 pin terminal block
STEP 2 – Connect wire to P1+, P1-, P2+, P2-, and the neutral wire to the ground screw.
STEP 3 – Plug connected 6 pin terminal block back into place. Or, Connect the P3 power DIN
from external power adapter.
WARNING – Always SHUT OFF power source to connect power wire.
WARNING – Always ground the power source to maintain a clean power input. Cheaply
made power supplies create too much noise and will cause the power input to fluctuate
when connected to this unit. To avoid this, always ground the power source to maintain a
clean power input.
