10083-0016 <br />CITY OF SOUTH BEND <br />capability. The circuits shall then be oversized as much as space permits for <br />maximum cooling of the board. All holes shall be plated through. The ten-ninal <br />strips shall be mounted on the board for connection of the above mentioned <br />wiring harness. Automotive transient suppressers must be incorporated into circuit <br />board at the point of cable entry to the board. All relays must include built in <br />noise suppression. The suppression must be accomplished with a IN4001 parallel <br />with the coil. The relay must have a 40 ampere continuous contact rating with one <br />form C contact arrangement. Normally open contact must have a maximum initial <br />voltage drop of 200 millivolts at 40 ampere contact load. The relays must <br />withstand 24 VDC for five minutes conducting rated contact current in case of <br />accidental 24 volt jump start condition. Circuit board options must be <br />programmable via jumpers to facilitate addition of options. The color of wire and <br />circuit number must be screened printed at the terminal block connections on the <br />board for rapid identification and relation to schematics. <br />Documentation that the above requirements are met must be included with the bid <br />document. <br />The printed circuit board shall incorporate red LED indicators for on board <br />diagnostics for input, output, and switching circuits for troubleshooting at a <br />glance. <br />CIRCUIT BOARD CERTIFICATION <br />The printed circuit board must meet the following specifications: <br />1. Packaging and Interconnecting Acceptability Standard number IPC 600 <br />2. UL-796 <br />3. Solder mask, IPC number SM-840 <br />4. Solder in conformance with MIL SPEC QS-571 <br />5. Laminate in conformance with IPC number 4101 <br />Certification must be included with this bid, <br />A service loop of wire or harness, per KKK -Al 822-F specification, shall be <br />provided at all electrical components, terminals, and connection points. All relays <br />shall be mounted for ease of serviceability. All high current diodes greater than 5 <br />amperes shall be heat sink mounted. provide the optimum circuit "overload" <br />protection, the electrical system's main circuit board shall allow for the use of stud <br />type automatic reset pole breakers. One spare 15 ampere circuit breaker shall be <br />provided for future use. A solid state electronic flasher shall be heat sink mounted <br />to the panel for control of the flashing warning light system. All wiring between <br />the cab and module shall be connected to a terminal strip(s) or block(s) or use <br />multi pin connectors on the electrical component panel and shall provide for <br />08/27/18 <br />30 <br />
