All Rights Reserved.10640205 February 2009Low Voltage Disconnect (if applicable)APS3-059, APS3-061 and APS6-059 dc power systems are equipped with a Low VoltageDisconnect (LVD) module. The LVD disconnects the batteries at the LVD disconnect voltageto prevent damage to the batteries due to excessive deep discharge. After the batteries aredisconnected, they recover to their open-circuit voltage. The LVD reconnects the batteriesautomatically after the ac supply is restored. After the batteries are reconnected, the APS dcpower system recharges the batteries and powers the loads.Both the LVD disconnect and reconnect voltages are configurable. The default LVDdisconnect voltage is set to 44V and the reconnect voltage to 48V. This hysteresis bandensures that the open-circuit recovery of the discharged batteries does not rise above the LVDreconnect voltage.Pre-InstallationWarningsThis section contains important warnings relating to:• Inputs• Equipment Classification• Outputs• Batteries (if applicable)• Rectifiers• Location and Environment• Servicing• EMC ComplianceInputs• Desktop Versions:Pluggable Type A: Except for 120V input, if APS3-06X power systems are fitted with three rectifiers, then onlytwo ac power cords may be connected to one building branch circuit. The third ac power cord must beconnected to a separate building branch circuit. Failure to do so voids all safety approvals.• The maximum earth leakage current of each Access Power Rectifier is 1.5 mA. Ensure that any upstreamResidual Current Devices (RCDs) are appropriately rated.• The ac power cords (supplying the power system) must be suitably rated for the environment and ac powerdistribution system. In addition, these ac power cords must be approved and installed to comply with localwiring regulations.• The earth conductor of each ac power cord must have a minimum cross sectional area of 1 mm2 (0.00155 in2).• The maximum length of each ac power cord should not exceed 3m (10 feet), unless local wiring regulationspermit otherwise.• Ensure that the ac supply is disconnected from those fused ac power sockets before checking or replacingtheir respective fuses.• Each socket, K1 to K3 (APS3), and K1 to K6 (APS6), contain two fuses, FS1 and FS2.CAUTION: DOUBLE-POLE / NEUTRAL FUSING• Use only 15 A, 250 VAC, 6.3 x 32 mm, fast-acting fuses of the same type (Bussman ABC-15 or Littelfuse 314-015 Type 3AB) for continued protection against risk of fire.
