NFS2-3030/E Installation Manual — P/N 52544:N1 07/18/2014 35UL Power-limited Wiring Requirements Installation3.10.4 Auxiliary Power Supply ConnectionsIf an optional auxiliary power supply is installed in the cabinet, connect it at this time. Follow theconnection procedures specified in your auxiliary power supply manual.3.11 UL Power-limited Wiring RequirementsPower-limited and non-power-limited circuit wiring must remain separated in the cabinet. Allpower-limited circuit wiring must remain at least 0.25 inches (6.35 mm) from any non-power-limited circuit wiring. All power-limited and non-power-limited circuit wiring must enter and exitthe cabinet through different knockout and or conduits. To maintain separations easily, it isrecommended that non-power-limited modules are grouped together. For example, use a separaterow or designated side of the enclosure so that power-limited and non-power-limited wiring do notcross. Install tie wraps and adhesive squares to secure the wiring.For a quick reference to control panel circuits, refer to Figure 2.1 at the start of this manual. Thepower-limiting label inside your cabinet door identifies which compatible modules have power-limited or non-power-limited wiring.Figure 3.19 Typical Wiring in a Four-Row BackboxComponent StatusCPU The green Power indicator will come on when power is coming from the mainpower supply.
