OfficeServ 7400 INSTALLATIONTECHNICAL MANUAL PART 5 MAY 20105.1PART 5. CONNECTING POWERThis section describes how to connect power to the OfficeServ 7400 system.5.1 BEFORE CONNECTING POWERWhen input power is normally supplied, the AC power is supplied to the Power Supply Unit(PSU), which charges the external battery. If the input power is interrupted, the system can beoperated using the charged power of the external battery. Verify that the AC voltage at the dedicated electrical outlet is in the range of 88-132 VAC(USA ONLY). A single AC outlet should be used solely for the system’s AC power. Sharing the AC powerwith other devices can cause noise or a voltage drop, resulting in a system malfunction orfire. Use a stable power source that can always supply AC power since instantaneous powerfailures can cause malfunctions or battery failures. System should be grounded as described in Part 1.2 and Part 2.5.5.2 PROCEDURE FOR CONNECTING POWERSINGLE CABINET CONFIGURATIONUse the AC power cable provided with the OfficeServ 7400 system to connect the inputpower terminal on the rear panel of the cabinet to a grounded outlet.Figure 5.1 Connecting Power (for Single Cabinet)
