Page 55 SmartFOAMMOTOR GROUND / PRIMARY POWERCAUTION!CONNECT THE PRIMARY POSITIVE LEAD FROMTHE TERMINAL BLOCK TO THE MASTER SWITCHTERMINAL OR RELAY TERMINAL USING MINIMUM 8AWG TYPE SGX (SAE J1127), CHEMICALRESISTANT, BATTERY CABLE AND PROTECT WITHWIRE LOOM.PREVENT CORROSION OF POWER AND GROUNDCONNECTIONS BY SEALING THESE CONNECTIONSWITH THE SILICONE SEALANT PROVIDED.GROUND CONNECTIONBe sure the Hale SmartFOAM system is grounded to thechassis. Use a short length of wide flat ground strap atleast 1-1/4” (32 mm) wide and less than 18” (457 mm)long to reduce the potential of RFI emitted by thisconnection.A stud is located on the mounting base to attach thechassis ground strap to the Hale SmartFOAM system.(See Figure 37: SmartFOAM Power and GroundConnections (1.7, 2.1)).When making the ground strap connections make surelugs are soldered to the strap ends for trouble freeconnections. Seal all connection against corrosion.When the length of the ground strap exceeds 18” (457mm) use a wider strap or a double thick strap.CAUTION!DO NOT CONNECT THE MAIN POWER LEAD TOSMALL LEADS THAT ARE SUPPLYING SOME OTHERDEVICE, SUCH AS A LIGHT BAR OR SIREN. THEHALE SMARTFOAM MODELS 2.1A AND 1.7AHPREQUIRE 40 AMP MINIMUM CURRENT.PRIMARY POWER SUPPLY CONNECTIONMake sure adequate switched electrical power from thebattery positive (+) terminal to the “IN” connection studon the motor controller is provided. (See Table 6:“Recommended Primary Power Cable Sizes”.)Use 8 AWG minimum type SGX (SAE J1127) batterycable directly to the battery, battery switch or solenoidsfor cable runs up to 6’ (1.8 meters) long. Longer wireruns may require larger battery cable for properoperation. DO NOT connect power to the sameconnection as the pump primer.RFI / EMIProper installation of system components and cablesalong with proper grounding will limit radio interferencecaused by the Hale SmartFOAM system. Additionally,make sure radio cables and hardware are not located inthe immediate area where Hale SmartFOAM equipmentis mounted.Making round coils of extra control and flow sensorcables in the pump compartment can act as an antenna.While the control and flow sensor cables cannot beshortened, various lengths of cable are available tominimize the “extra” cable in the truck.When routing control and flow sensor cables take care toavoid routing them next to antenna wires, radio powerlines and radio components. When there is extra cable,double the cable back on itself and secure with plasticwire ties in a flat bundle instead of making a round coil.(See Figure 38: Extra Cable Storage).Figure 38: Extra Cable Storage |
