Page 4: Introduction
Introduction This Central Inverter System integrates the latest power electronics and microprocessor technology which produces a pure sine wave power output intended for use in Emergency Lighting. The system is very efficient on-line and typically has a standby power loss of only 2 percent of the systems total capacity which means it is 98% efficient. - Page 5 The Inverter utilizes a bi-directional converter that is either MOSFET or IGBT technology based on the DC voltage of the system. The system does not require installers to go through a manual pre-charge and dis- charge procedure to start the system up because these components are built into the Inverter Modules. The overload capabilities of the system defined by its crest factor (minimum of 4.0) which means that universal ballasts and drivers present no issue starting up on Inverter Power and it can sustain a minimum of 400 percent for about a half second.

Page 6: Receiving And Storage
Receiving and Storage Inspection The Cabinets and Batteries may be shipped on the same pallet or may be shipped separately. Upon arrival please inspect the contents to ensure that no shipping damage has occurred. This is especially important with the batteries – ensure that there are no cracks or leaks. If any damage has occurred notify the shipping carrier immediately and submit a damage claim. -
Page 7: Installation
Installation Location NEC article 700 EMERGENCY CIRCUITS should be referenced for proper installation of a Central Inverter System. Article 700 dictates that unit must be mounted in a permanent location. Choose a cool dry place with normal ventilation and one which will allow easy access for testing and maintenance. Avoid a location which could allow vandalism and tampering with. - Page 8 Figure 1 – Overall Dimensions Diagram shows both side by side and top and bottom mounting configuration. Top and Bottom mounting configuration is factory preferred for control panel access. Battery Cables from Factory are sized for top and bottom mounting configurations.

Page 9: Knockout Locations
3.4.3 Knockout Locations EKO’s (Electrical Knock Outs) are provided on the Left side, Right side and also the Top side surfaces. Ensure all metal conduit is secured and tightened creating a good connection to earth ground. Use an Ohm-Meter to check that continuity between conduit and protective earth ground has been established. -
Page 10: Ac Connections
AC Connections WARNING – Only qualified personnel that are familiar with AC and DC installation techniques and codes (such as an electrician) should perform the Installation. WARNING – This system contains lethal AC Voltages. Because of these hazards of high voltage electrocution, always shut down all sources of power before you install, maintain, or service the unit. -
Page 11: Removing The Ac Breaker Cover
Removing the AC Breaker cover To access wiring to the breakers, remove the two ¼-20 screws from the plastic breaker cover with a 3/8 socket or nut driver and the circuit breakers cover will easily remove. This cover conceals the wiring area and also provides a safety barrier so that fingers cannot inadvertently touch live parts after installation. -
Page 12: Installing The Output Wires
Installing the Output Wires Connect the load wires to the provided terminal block labeled N. On. If switched loads were installed from the factory, connect the switched loads to the breakers to the right of the input breaker. There are dedicated neutral and ground blocks which should be shared for the AC input and AC output. -

Page 26: Battery Charging Mode
INCORRECT AC – The wrong voltage is being applied to the system After all the Start-Up diagnostics are performed, the system is OK to proceed to the Battery Charging mode. Battery Charging Mode The Battery Charging mode is where the system will remain for 99.9+ percent of its life. In this mode, AC power is being passed through to the units output and subsequently its loads and the batteries are keeping a float charge. -
Page 27: Inverter Power Mode
The Switched output can be energized while in the Battery Charging mode of operation by applying 120 or 277 VAC to the Switched Enable Input. When this system changes mode of operation to the Battery Power mode, the Switched Output will automatically energize. -
Page 28: Warranty
10.0 Warranty There are two separate warranty periods for this Central Inverter System. The Electronics/Cabinet warranty period is for 3 years from the date of shipment. It is warranted against defects in workmanship and materials under normal and proper use. The batteries are covered under a separate warranty and these durations may change dependent on battery type. -
Page 29: Maintenance And Service
11.0 Maintenance and Service CAUTION – Whenever maintenance and service is to be performed, it may be desirable to shut unit down. Please refer to Start up and Shut Down procedures for details. CAUTION – Always assume AC and DC Voltages are present at the output terminals because the system is capable of providing output voltage from the batteries when there is no AC input. -
