(6) 严禁电缆平行敷设在油管路的正上方或燃气管路的正上方，以及在油管路接口的下方通过。
(7) 计算机的输入输出信号电缆应敷设在带盖的电缆槽中，电缆槽道及盖板应保证良好接地。单根信号电缆应穿在钢制电缆管中敷设，电缆管要保证良好接地。电缆屏蔽层宜选用铜带屏蔽或铝箔屏蔽。
3、现场接地常用注意事项
DCS系统对接地要求比较严格，在现场接地时一定要严格按照DCS厂商的接地规范严格接地，否则会影响DCS系统的可靠性。对DCS系统现场接地时应注意以下几点：
(1) I/O柜的电源地与UPS的电源地必须接至同一个地，保证等电位。
(2) 接地电缆必须符合DCS厂商的要求，并要接到机柜内专用的接地螺丝上。
(3) 系统接地与屏蔽接地不能在机柜汇合，必须单独接入到接地网。
(4) 柜间接地不能用机柜并接螺栓代替，必须用接地线严格连接。
(5) 接地要牢固可靠，汇流连接板并要涂防腐漆。
(6) 接地电阻符合DCS系统要求，并要进行严格的测定。
(7) 接地严格按照DCS厂商接地要求接地，不能为了省事走捷径或不按照接地线线径要求进行接地。
