•
Ensure that the polarity of the DC input wiring is correct. Under certain conditions,
connections with reversed polarity might trip the primary circuit breaker or damage
the equipment.
•
For personal safety, connect the green and yellow wire to safety (earth) ground at both
the router and the supply side of the DC wiring.
•
Because the router is a positive ground system, you must connect the positive lead to
the terminal labeled
RTN
, the negative lead to the terminal labeled
–48V
, and the earth
ground to the chassis grounding points.
