CAUTION: To maintain all compliance ratings, keep AC input voltage between 100 V to 120 V
or 220 V to 240 V.

The Neutrik PowerCon AC mains inlet on the rear panel accepts the
detachable power cords supplied with the unit.
120 V AC mains:
Use the 3-wire grounded AC cord with the NEMA
5-15 plug.
230 V AC mains: Use the 3-wire grounded AC cord with the
Schuko plug.
CAUTION: It is the user’s responsibility to provide a proper AC
mains plug for any AC mains outlet configuration that differs from
those supplied with the product.

The chassis of this product is grounded through the grounding conductor of the power cord. To avoid
electric shock, plug the power cord into a properly wired and grounded receptacle before making any
connections to or operating the product.
DANGER: This equipment must be operated with the power cord grounding conductor
connected to a properly grounded AC outlet. Do not disconnect, “lift,” or otherwise remove this
ground connection. Without this connection, accessible parts, including knobs and controls that
may appear to be insulated, can render an electric shock that can cause injury or death to
operating personnel.
Connect the supplied AC mains cord to the PowerCon jack on the rear of the loudspeaker. The
PowerCon system uses a locking connector. To lock, twist 1/4 turn clockwise after fully inserting it into
the receptacle. Then, connect the other end of the cable to the AC mains supply receptacle. This will
energize the loudspeaker.

The Neutrik PowerCon AC mains and AC loop connectors are wired in parallel to provide an AC mains
inlet and outlet on each NTL720.
The blue AC mains inlet mates with a Neutrik PowerCon NACFC3A (supplied). The
white AC mains outlet mates with a Neutrik PowerCon NACFC3B (also supplied).
Therefore, to loop the AC mains from enclosure to enclosure, connect the AC mains
jumper cable as shown. Up to four NTL720s can be looped in this fashion.
Use the AC loop connector to daisy-chain AC mains power from one enclosure to
another. The maximum, continuous load must not exceed 12 A for the 115 V
version and 6 A for the 230 V version.
NOTE:
The circuit breaker only protects the AC Loop outlet, not the AC
Mains connector. If the continuous load connected to the AC Loop outlet
exceeds the rated load, the circuit breaker will trip. For this situation, reduce
the connected load and then manually reset the circuit breaker.
