used, be sure a dedicated, grounded outlet is used. Conduit must enter controller where t prepunched conduit holes are provided. C. Dig trenches as necessary, and install conduit from the controller to each probe location. Probe wire must enter controller through the proper prepunched conduit holes. D. The conduit can enter the probe manhole through the bottom or side. The end of the conduit should be as high as possible to reduce the chance of water covering the junc- tion box during heavy rain. E. Lay 3/4" rigid metal conduit from each probe to a junction box or wiring trough. located in- side the building. Conduit must enter control- ler where prepunched conduit holes are provided. No other conduit entry is permitted. WARNING: Explosion may occur if other wires share the X76 ETM's probe wire con- duit. Conduit from probes to controller must not contain any other wires. ' WARNING: Explosion and equipment damage may occur if conduits do not enter the con- troller through their designated prepunched conduit holes. ' Failure to comply with these warnings could result in serious personal injury, property loss and equipment damage. ' Wiring between the probes and the controller is designed with limited electrical power to probe wires so there is insufficient energy to ignite fuel. To maintain this safety feature, probe wires must be installed in a separate conduit from all other wiring. Probe wires MUST NOT be run in same conduit as power wires. ' 3.4 Probe Junction Box And Vapor Seal Installation ' Install a vapor seal at both ends of the conduit. One end must be at the probe end of the conduit and the other end before the the conduit enters the building. Install a weatherproof electrical junc- tion box with a gasketed cover at the end of each conduit at the probe location. ' 3.5 Probe Wiring Pull the twisted pair shielded cable. #22 AWG or heavier, between the controller and each probe location. The wires must be designed for use in the presence of gasoline and/or oil, and the con- duit must be sealed in accordance with the Na- tional Electrical Code, (NFPA 70), and meet the specification pertaining to the product being monitored as defined by Flammable and Com- bustible Liquids Code, (NFPA 30), and other local codes, since they pass from a Class I, Division 1 area into a non -hazardous area. WARNING: Explosion may occur if other wires share the X76 ETM's probe wire con- duit. Conduit from probes to controller must not contain any other wires. 4.0 COMPONENT INSTALLATION WARNING: The installation and use of this product must comply with the National Electrical Code, federal, state and local codes, and any other applicable safety codes. In addition, take the necessary precautions during installation, ser- vice and repair to prevent personal injury, proper- ty loss and equipment damage. WARNING: Turn off power to the system before opening the front panels to avoid shock from the power supply. In addition, power to the system must be turned off before opening or securing the barrier cover. If high voltage is shorted across any barrier probe terminal, explosion or fire could result. 4.1 Controller Installation Mounting: Select a mounting location on the in- side wall of an enclosed building, protected from severe vibration and extreme temperature. The monitor should be mounted with the LCD at eye level. Wiring: A. Open controller cover, remove the screws holding the barrier plate and remove the plate. B. Locate the input power terminal on the left edge of the board between the top and bottom edge of the board. See controller wiring con- nection diagram on page 16. Connect the wires from the breaker box to the controller, in- cluding the earth ground. Figure 47: A 1 t j m n5lan>uui I.
