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 4 - Terminate the earth conductor at APS1 Position the APS in front of the rack.2 Pass the ac supply cable through the ac cable entry gland.3 Terminate the earth conductor with an M6 crimp lug. Ensure the ferrule of the crimp lug covers all strands of wire.4 Connect the earth conductor to the earth termination point next to the ac cableentry gland (see the diagram on page 3 or diagram).Step 5 - Terminate the conductor(s) at MCBs (if fitted)Ignore this Step if ac MCB(s) are not fitted.Connect the phase conductor(s) to the MCB(s) and the neutral conductor (if fitted) tothe adjacent terminal block. Connect according to the labels fitted to the MCBs and neutral terminal block.Step 6 - Terminate the conductor(s) at terminal blocks (no MCBs fitted)Ignore this Step if ac MCB(s) are fitted.1 If the ac supply is 1-phase or 2-phase (L1/L2) then loop together the three live (L)terminal blocks.2 Connect the phase conductor(s) and the neutral conductor (if fitted) to theterminal block. Connect according to the labels fitted to the terminal blocks.
