1-24
When connecting NetEnforcer to 120 / 240 VAC supply, plug into 10 A service
receptacles, type N5/10 or NEMA 5-10R. Ensure that each site has a suitable ground.
Ground all metal racks, enclosures, boxes and raceways. The NetEnforcer equipment
should be reliably grounded through the power supply cord.
Connection to DC Power
CAUTION
Use a UL listed 10A circuit breaker between a centralized DC power
system and the NetEnforcer power entry module
.
Before performing the following procedure, ensure that power is removed from DC
circuit.
1.
Verify that power is off to the DC-input circuit.
2.
Wire the DC-input power supply to the terminal block, ensuring that all
wire connections are secure (suggested DC-input wires are 14-AWG
copper UL listed conductors):
•
Ground wire to the ground connector (you should always connect the ground
wire first and disconnect it last).
•
-48V wire to the - connector.
•
+48V return to the + connector.
3.
Restore power to the DC circuit by turning the circuit breaker on (|). Do
not restore power until you are ready to boot the NetEnforcer system.
This unit is intended for RESTRICTED ACCESS LOCATIONS in accordance with
NEC (National Electric Code) or the authority having jurisdiction. Power supply cable
comprises two sets of 2x14 AWG copper wires; use UL-listed cable only.
When connecting NetEnforcer to 48/60 V , use a UL-listed 10A circuit breaker between
the centralized DC power system and NetEnforcer power entry module as the
disconnect device incorporated in the fixed wiring. The circuit breaker must be close to
the NetEnforcer and easily accessible.
