WARNING
Electric Shock Hazard! No connections (including neutral) may be shared between groups of dispensers.
A separate Control Power Circuit Breaker must be provided for each group. Failure to do so may result in
serious injury.
2.6.3 Field Wiring for Dispensers Without a Junction Box
All field wiring must enter the Electronic Head via potted conduit/conduit fittings . When a dispenser
does not contain a junction box, the conduits must be potted in the field during dispenser installation.
Note: This also applies to the secondary conduit containing the Ethernet cable and the intercom call button/
speaker wires even if the dispenser does have a junction box since these wires do not connect in the junction
box.
1. Install (2) 3/4” field conduits from the UL approved seal-offs at the base of the dispenser to the conduit at
the vapor barrier as identified in Figure 2-5. One conduit will contain, as applicable, the Ethernet cable
and the intercom (call button and speaker) wires (low voltage - Class 2 circuits). The other conduit will
contain the pump power, relay selects, valance lighting and data wires (Power - Class 1 circuits).
2. Clean conduit threads before connecting.
3. Pull continuous uninterrupted lengths of wires from the station electrical panels and control boxes to the
dispenser electronic head. Allow an extra 18” lengths past the vapor barrier fitting for terminating,
separating, potting and connecting to the terminal block. If installing iX CAT or IDPOS dispensers, allow
an extra 3 ft. of Ethernet cable past the top of the conduit in the vapor barrier.
4. From each conduit, separate the wires using 3-201623 Wire Separator Gasket. See Photo 1.
5. Roll separator gasket and wires into a cylinder and secure with electrical tape. Photo 2 and Photo 3.
6. Pull separator gasket and wires back through the conduit fitting (Photo 4) forming a dam in the conduit,
with the top of the separator down in the conduit past the dimple in the conduit.
