Installation

Junction Box Specifications

Encore units are provided without junction box unless the junction box option is specified at
time of order. If replacing and existing unit, installing contractor may connect and extend
existing wires that are too short for Encore by providing and utilizing a Class 1 Division 1
explosion-proof junction box sized to conform to or exceed the requirements of both UL87
and the National Electrical Code NFPA 70.

Note: These specifications may have requirements which are not identical.

Note: Gilbarco does supply junction box kits. Refer to MDE-4084 Junction Box Retrofit Kit

M01483K006 Installation Manual for additional information.

Wiring Dispenser (STP-Supplied Unit)

Depending on the installation the electrician will be routing conduit directly to the electronics
cabinet, to a factory installed junction box or to an installer supplied junction box and then to
the electronics cabinet.

For Pump Wiring see

Wiring Pump (Self-Contained Unit) on page 34

Preparing Field Wiring

Open Side 1 CIM door. Refer to MDE-3804 Encore and Eclipse Service/Start-Up Manual for
instructions.

Note: Side 1 has electronics module access to field connections, boards and wiring. Main

junction box is installed on side 1 for units with factory installed junction box.

For units with junction box installed, remove box cover and save for reassembly.

Note: For Encore units replacing older units, if existing wire is too short to reach cabinet

connections and a splice must be made, contractor must provide and use a Class 1

Division 1 explosion proof junction box in which to make connections according to

code. Refer to section

Before Placing Unit on Fuel Island on page 14

Verify that a Seal-Off Y fitting has been installed and sealed as a first connection where
conduit leaves ground. This fitting must be in place and sealed before proceeding further.
Refer to MDE-3802 Encore and Eclipse Site Preparation Manual.

In all cases where junction box is used, whether factory or contractor supplied, the following
are mandatory requirements:

Connection of conduit to junction box must be made with a clearance of at least 9 inches

from pump/dispenser base to the bottom of the junction box connection stub. To
accomplish this, conduit can be routed so as to enter junction box from side or top.

Junction box must be securely fastened in unit by means of a bracket or brace, and cannot

be held in place by only conduit. Factory supplied boxes are so fastened.

Installation of junction box and all fittings must be done so as to allow installer to turn any

and all threaded fittings a minimum of 45 degrees in a single movement using appropriate
tool, for example; pipe wrench.

Wiring must be gas and oil resistant, color coded or tagged for identification purposes, and

rated for 300 Volts or higher. Data wires for new installations must be twisted-pair
(unshielded) with 10 to 12 twists per foot.
