Installing the PA0338X00X D-Box
PA0338X00X D-Box Installation
Basic Site Criteria
D-Box installation must be in accordance with NEC NFPA 70, Automotive and Marine
Service Station Code NFPA 30A, and state/local electrical requirements. For Canadian
installations, use Canadian Electrical Code CSA 22.1. The site must be equipped with electric
service allowing compliance with all installation requirements of a complete fueling system
and with MDE-3620 POS Site Preparation Manual.
Physical Placement
Install the D-Box in an area not subjected to extreme temperate variations. The ambient
temperature must remain relatively constant. Do not install the D-Box in a position subjected
to direct sunlight. If a stable temperature environment is unavoidable, provide a suitable
sunscreen.
Electrical Wiring Requirements
The receptacle that provides power to the D-Box must be a properly installed isolated ground
receptacle (Hubbell
®
#IG5261 or equivalent). This type of receptacle is easily identified by its
bright orange color and by the triangle embossed into the face of the outlet. The green
grounding screw must be attached to the grounding conductor.
Ensure the following:
• All electrical wiring must conform to the NEC and local wiring codes, as well as the
criteria provided in this manual (refer to
on
• One conduit from the breaker panel to the D-Box location is required. The conduit must
contain a dedicated/isolated circuit with three 14 AWG wires: 115 VAC hot, neutral, and
ground or 230 VAC L1, L2, and ground. Do not use the electrical conduit to provide an
earth ground. It is necessary to have the D-Box on the same phase as the CATs.
• The circuit powering D-Box must not power other devices. The circuit must not share a
conduit with wiring for devices drawing high amperage (for example, compressor,
freezer, and so on) or devices that are sources of Radio Frequency Interference (for
example, TV, microwave, intercom, and so on).
• An AC outlet must be located within 6 feet of the D-Box. Do not use extension cords.
Note: For 230 VAC operation, a nine-foot detachable line cord is provided. It is the
customer’s responsibility to supply a plug for the cord that meets local electrical
codes and UL requirements.
