STP Isolation Relays for Electronic Dispensers
STP isolation relays provide electrical isolation between dispensers and prevent damage from
cross phasing. Refer to MDE-2755 Gilbarco STP Control and Dispenser Isolation Relay Box
PA0287 and FE-321 Gilbarco STP Isolation Relay Box PA0287.
Note: For 3-phase STP, use isolation relay at the input of the 3-phase STP control box.
• Gilbarco requires installation of STP
isolation relays in addition to STP control relays.
Combined STP Control Relay/Isolation Relay boxes are recommended.
• Isolation relays must be installed f
or each STP control line at each dispenser or dispenser
grouping on a single circuit breaker.
• Neutral wire must be routed to the control relays from the disp
enser circuit breaker (For
more information, see “Appendix: Wiring Diagrams” on
page A-1).
Wiring
For high speed communications information, refer to “Twisted-pair Conduit” on page 9-4.
• All circuits must be class 1 N.E.C
wired except the speaker (intercom) circuit, which must
be class 2 N.E.C. The speaker (intercom) circuit requires a separate 1-inch conduit.
• Only stranded gas and oil-resistant copper wire rated for 300 V
olts (up to 240 VAC source)
and 176°F (80 °C) may be used.
• In the main conduit, for communications, only twisted-pair
, Two-wire data pairs may be
used.
• All dispensers must be wired on the same phase.
Note: If the Gilbarco isolation relay box is installed
, dispensers are not required to be on
the same phase.
• Only listed wire nuts may be used for connections. Tape is not permitted.
• Seal-off Y fitting(s) must be potted after all wires are run and tested to t
ermination points.

Note: When installing new two-wire communication wiring, use unshielded twisted-pair data
wires. Do not use shielded wires. Wiring specifications: two-wire twisted-pair (UTP)
with 10 to 12 twists per foot, stranded annealed copper tinned with 18 AWG minimum
required for runs up to 1000 feet or 14 AWG minimum for runs up to 2600 feet. Do not
use daisy chain communications wiring. Insulation specifications: Polyvinyl chloride
(PVC) insulation of type TFFN or MTW, UL-approved gasoline and oil-resistant. Refer
C&M Corporation Part #27525 (18 AWG) or equivalent. Gilbarco part number for the
wire is Q13221-02.
