1.5.1 Grounding the KSUEnsure all Main and Expansion KSU(s) are powered off and unplug the ACcord.In each KSU, connect the ETH lug to the verified grounding point using a minimum cable size of14AWG (Φ2.0 mm) wire.ETH Lug To EarthScrewFigure 2-18 ETH Lug• The grounding cable is supplier-provided.(not attached to the system)1. Loosen the screw.2. Insert a grounding wire (user supplied).3. Tighten the screw.4. Connect the grounding wire to earth ground.Proper grounding is very important to protect the system from externalnoise and to reduce the risk of electrocution in the event of a lightningstrike.1.5.2 AC Power RequirementA dedicated 100V-120V/220V/230V/240V 50/60Hz circuit located within two meters of the KSU isrequired. A separate dedicated AC outlet is necessary for each KSU.Double Pole/Neutral Fusing(Power supply fuses are located at both the L and N side.)Table 2-5 Power Requirement110 VAC 220 VAC 230 VAC 240 VACPower Require-ments110 VAC@15 A 220 VAC@15 A 230 VAC@15 A 240 VAC@15 APower Con-sumptionMain KSU = 144 VA4 KSU Total = 576 VAMain KSU = 172 VA4 KSU Total = 688 VAMain KSU = 175 VA4 KSU Total = 700 VAMain KSU = 175 VA4 KSU Total = 700 VAInput Voltage(Rated Voltage) 90 VAC to 264 VAC (100VAC/120VAC/220VAC/230VAC/240VAC)Frequency 47 Hz - 63 Hz (Rated Frequency:50/60 Hz)Phase and Wire Single Phase, 2 Line + PE TypeGrounding Re-quirement No.14 AWG Copper WireISSUE 3.0 SL1000Hardware Manual 2-13
