Referto the ac connection diagrams in Step 6.Access Power Solutions dc power systems can only be connected to one of thefollowing:AC source Voltage (nominal)* AC MCB(if fitted)1-phase, neutral and Protective Earth (PE) 220-240V phase-neutral 1-pole2-phase and PE 208V phase-phase 2-pole (linked)3-phase, neutral and PE 220-240V phase-neutral 3-pole3-phase and PE 208V phase-phase 3-pole (linked) *See Specifications on page 69 for the ac voltage range.Step 4 - Prepare the ac supply cable1 Select ac supply cable to suit the ac supplysource, the maximum ac current (seeSpecifications on page 69) and in accordancewith the local wiring regulations.2 Route the ac supply cable from the ac supplypoint into the rack. Then bring the cable throughthe front of the rack to the APS.Do not terminate at the ac supply point at thisstage.3 At the APS end, cut the conductors to suit thepositions of the terminals (and ac MCB(s) iffitted). Ensure the earth conductor is 30-50mm (1¼ - 2inches) longer than the longest phase or neutralconductor. Rack cabinet Proposed position of APS AC cable from supply point(top or bottom entry intorack as required).Step 5 - Terminate the earth conductor at APS1 Position the APS in front of the rack.2 Terminate the earth conductor with an M6 crimp lug. Ensure the ferrule of the crimp lug covers all strands of wire.3 Connect the earth conductor to the earth termination point next to the acterminals (see the diagram on page 3).
