SYSTEM LAYOUT
1.
Verify that the system is installed with a minimum clearance of 18 inches between the post
and any of the pumps or dispensers. This clearance meets the NFPA 30A and NFPA 70
requirements and allows room for wiring and maintenance of the system. Adequate
clearance around the head of the unit is important to provide room for maintenance of the
system. A minimum of 14 inches of clearance from the rear of the unit must be provided to
allow the rear door to open.
2.
Remove the 10 screws from the upper side pedestal cover. Unlock and remove the cover.
Remove the 10 screws from the lower side pedestal cover and remove the cover (same side
of post as the upper pedestal cover).
3.
Verify that the conduit is installed according to the following specifications:
All wiring (AC and DC) connecting the different components of the Series 1000 System must
be installed in metal conduit. PVC IS NOT ACCEPTABLE. Components of the system
include pumps, dispensers, submersible pumps, submersible starter relays, Series 1000
System, and circuit breaker panels. Communications equipment signal wires should also be
run in metal conduit, (except for RS-422 wiring as noted below).
High voltage AC power wires must be installed in separate conduit from the low voltage DC
signal wires. The AC power wires and DC signal wires must not be run in any sort of
common conduit or trough (except for RS-422 wiring as noted below). All conduits should be
connected to the Series 1000 pedestal through the holes and knockouts provided by the
factory. No other holes should be made in either of these units unless previously approved
by GASBOY.
All wiring and conduit runs must conform with the National Electrical Code (NFPA 70), the
Automotive and Marine Service Stations Code (NFPA 30A), and State and Local Electrical
Codes.
Conduits for the system port wiring must be as follows:
RS-232 wires must be installed in a metal conduit separate from any AC wires.
RS-422 wires should be installed in a metal conduit separate from any AC wires. The use of
shielded two twisted pair cable (Belden 8102 or equivalent - GASBOY P/N C08728) allows
for the following exceptions:
•
The cable can be run with AC wires in metal conduit. The shield drain wire must be
connected to the system AC ground.
•
The cable can be run indoors without the use of metal conduit. The shield drain wire
must be connected to the system AC ground. In no case should the cable be run
outdoors without the use of metal conduit. Whenever possible the conduit should be
run underground and not overhead.
•
A short haul modem (SHM) must be used for RS-422 communications.
