Pour réduire le risque de choc électrique lors de l'entretien/révision, coupez totalement le courant à
la pompe/distributeur. Dans les applications de pompe immersible, coupez totalement le courant à
la pompe immersible et tous autres distributeurs qui utilisent la pompe immersible. Le courant
alternatif peut alimenter de nouveau un distributeur à l'arrêt quand les distributeurs partagent une
pompe immersible commune ou un relais de démarrage.
AVERTISSEMENT

Note: Refer to the appropriate Site Controller Installation Manual for additional wiring
considerations.
Power Requirements
System/Peripheral Equipment
AC power for CFN system components, data terminal, and external modem must be supplied
from a separate, dedicated circuit breaker. No other equipment, including the system's pumps
or remote dispensers may be powered from this breaker. Whenever possible, one breaker
should be used to supply power to the CFN system components, data terminal, and modem.
However, it is acceptable to supply power to different CFN system components and
accessories from multiple breakers within the same breaker panel and same phase of power.
When necessary, power for the data terminal or modem may be supplied from a separate,
dedicated breaker located in a different breaker panel.
The system requires 120 VAC + 10% 47-63 Hz for power. A Profit Point PLUS console and its
attached components (receipt printer, RS-485 to RS-232 converter, POS D-Box, and possibly
a scanner) must draw power from an AC Surge Protector Outlet Strip that cannot be plugged
into an optional power conditioner. Whenever possible, the AC Surge Protector Outlet Strip
and optional power conditioner must draw their power from the same source.
Proper system grounding is an important aspect of system installation. As with the AC power,
the grounds for all CFN system components should return to the same breaker panel. This
helps in assuring a common ground throughout the system, that is necessary for protection of
the RS-485 data loop circuitry. Grounds for all system devices should be wired to the breaker
panel ground bus bar, which in turn should be grounded to a ground rod. A conduit ground
does not provide a sufficient ground. It is recommended that neutral and ground bus bars be
bonded together when it is not prohibited by local codes.
