Electrical Requirements
• Sites must be prepared according to NFPA 30A, NFPA 70, and applicable national, state
and local codes/regulations.
• All circuit breaker panels and relay boxes must be mounted securely to the wall.
• Only UL recognized/approved components and/or systems may be used.
• Licensed electricians experienced with pump and dispenser installations must be used to
make all electrical connections.
• Installation requires a dedicated circuit phase system. All electronic units must be wired to
the same power leg.
• An earth ground is required for all circuits.
Emergency Power Cutoff Switch
• NFPA 30A and Gilbarco require installation of one or more emergency power
cutoff switches.
• An emergency power cutoff switch is a single control that removes AC power to all island
equipment (pumps/dispensers, STPs, canopies, lights, and so on.). See Figure 4-1 on page
70 .
• The emergency power cutoff switch must be accessible, labeled clearly and installed away
from any hazard that may occur at the pumps/dispensers. Cutoff switches must not be
located more than 100 feet away from the pumps/dispensers.
Electronic
cabinet The Encore Series electronics cabinet has two field conduit inlets. Facing side 1, the ones to the
center left are for power wiring while the ones to the center right are for intercom/Ethernet/call
button/ speaker wiring. In The Advantage Series, the power goes into the junction box and
intercoms, and so on, usually in a special conduit up a side column. Ethernet will be an option on
future Encores with installation of an optional board in the electronics cabinet. All Encores have
knockouts for Ethernet wiring although the option board is not currently available. Ethernet wiring
can share conduit with a speaker/intercom/call button.
Wiring in
electronics
cabinet The Encore Series units use wiring terminal blocks as appropriate for field wiring where The
Advantage Series uses wire nut connections.
Mandatory
conduit
potting
requirements The installer must pot each conduit entering the electronics cabinet in two locations as specified in
this manual. One is at entry into the electronics cabinet and the other is in the pit box. The
Advantage Series units only require potting below the unit.
Calibration All Encore meters are electronically calibrated. Advantage meters are mechanically calibrated.
