E. PROBE SENSOR CONDUIT INSTALLATION. To the installer: Read and carefully adhere to the instructions in the following warnings during conduit installation! 9 WARNING: EXPLOSION COULD OCCUR IF OTHER WIRES SHARE CONDUITS OR TROUGHS WITH PROBE OR SENSOR WIRING. CONDUITS AND WIRING TROUGHS FROM EMC PROBES AND SEN- SORS MUST NOT CONTAIN ANY OTHER WIRES. .111 WARNING: EXPLOSION AND/OR EQUIPMENT SO 12. IV DAMAGE COULD OCCUR IF CONDUITS DO NOT ENTER THE EMC MONITOR THROUGH THEIR DESIGNATED PREFORMED KNOCKOUTS. FAILURE TO COMPLY WITH THESE WARNINGS COULD RESULT IN DEATH, SERIOUS PERSONAL INJURY, PROPERTY LOSS AND EQUIPMENT DAMAGE. 1. Wiring between the EMC monitor, probes, and sensors limits the electrical power to the probes and sensors so that there is insufficient energy to ignite fuel. To maintain this safety feature, install EMC probe and sensor wires in separate conduits from all other wiring. ,' NOTE: Wiring from separate EMC probes and EMC "® sensors may be run in the same conduits or troughs providing they are powered by the same monitor. CAUTION: IMPROPER SYSTEM OPERATION WILL RESULT IF PROBE AND SENSOR WIRING FROM SE- PARATE EMC MONITORS SHARE THE SAME CON- DUIT. DO NOT RUN PROBE AND SENSOR WIRING FROM SEPARATE EMC SYSTEMS IN THE SAME CONDUIT. Never run any probe and/or sensor wires in the same conduit or trough as power wires! 2. Run conduit from all probe and sensor locations to the EMC monitor location. The conduit layout should be de- signed to best suit the requirements of the site, and must conform to Federal, state and local codes. Knockouts for 3/a", 1" or 1'/a" I.P.S. conduit are provided in the intrinsically -safe area of the monitor . You must conform to the National Electrical Code and state and local codes and consider the number of wires entering the monitor when deciding on the size and number of conduits required for probe and sensor wiring. 3. The conduit must be properly sealed in accordance with the National Electrical Code (NFPA 70) and the Auto- motive and Marine Service Station Code (NFPA 30A) since they pass from a Class I, Division I or Division II area into a nonhazardous area. Site Preparatt n and Installation Instructions EMC UST Monitoring System F. •e AND SENSOR JUNCTION `r INSTALLATION. Install a weatherproof electrical junction box with gasketed cover on the end of each probe and sensor conduit run at the manhole or monitoring well location. Gasketing or sealing compound must be used at each entry to the junction box to ensure a waterproof junction. The interior of each junction box must be a minimum of 16 cubic inches. Use one of the approved units shown in the following listing or an equivalent unit. Typical Sensor and Probe Junction Boxes: Manufacturer: Appleton Electric Co. 1701 W. Wellington Avenue Chicago, IL 60657 Tel: (312) 327-7200 Description Catalog Number Quantity Junction Box JBDX-75 1 Cover, Junction Box JBK-B 1 Gasket, -Junction Box JB -GK -V 1 Manufacturer: Crouse -Hinds Co.

At each probe and sensor location, install a 14 -inch minimum diameter approved manhole according to the manufac- turer's instructions. Offset the probe or sensor riser pipes within the manholes for ease of junction box installation and wiring. Leave enough space between the junction box and manhole liner so that the junction box can be removed if necessary.
