- Page 12 AO Option Operation The AO Option is designed for use with the VST Series of inverter power systems. The option will bypass one 0 to 10 volt local dimmer switch as well as allow user-programmable setting of emergency output lighting levels. Two load terminals as well as two dip-switch sets for independent output settings are provided to allow 25%, 50%, 75% or 100% of nominal illumination output during power outages.
- Page 13 4C OPTION OPERATION The inverter power system’s 4C option allows lighting fixtures or other load types on circuits controlled by local switching devices to be easily connected to and powered by the VST system during utility power outages. The 4C option provides four local switching device override circuits which, under emergency mode operating conditions, automatically disconnect the load side of the local control device(s) and connect the selected loads to the inverter output assuring normal operation of connected loads...

106.3 Battery Connection Voltage Check Using a digital volt-ohm meter, check for correct nominal battery voltage between DC Input NEG and POS wires. Refer to table in Section 106.2 for proper system DC voltage. Voltage reading should be ±10% of system DC voltage. 107. -
Page 17: 200.1 Safe Shut Down Procedure
200. Maintenance 200.1 Safe Shut Down Procedure CAUTION: To avoid possible equipment damage or personal injury, assume that there is AC voltage present inside the VST inverter system unit any time AC input power or DC battery voltage is applied. The inverter is capable of providing output voltage from the batteries even when there is no AC input line voltage. -
Page 18: 200.4 Routine Battery Inspection And Maintenance
200.4 Routine Battery Inspection and Maintenance Sealed Lead-Calcium Batteries Lead-Calcium cells are the most common type of battery used today in standby equipment. By design it is as maintenance free as a battery can be. It is recommended, however, that some simple steps be taken to increase system life and maximize reliability: A) A quarterly visual check of the batteries should be conducted to look for deformities in the cases and terminal corrosion.
